        Safety Information
        Passage making under autopilot control is an enjoyable experience
        that can, if you are not careful, lead to the relaxation of the
        permanent watch. A permanent watch MUST be maintained no
        matter how clear the sea may appear to be.
        Remember, a large ship can travel two miles in five minutes ­ just
        the time it takes to make a cup of coffee.
        The following rules should always be observed:
     · Maintain a permanent watch and regularly check all around for
       other vessels and obstacles to navigation ­ no matter how clear the
       sea may appear a dangerous situation can develop rapidly.
     · Maintain an accurate record of the vessel's position either by use of
       a radio navigation receiver or visual bearings.
     · Maintain a continuous plot of position on a current chart. Ensure the
       locked autopilot heading steers you clear of all obstacles. Make
       proper allowance for Tidal Set ­ the autopilot cannot!
     · Even when your autopilot is locked onto the desired Track using a
       radio navigation receiver, always maintain a log and make regular
       positional plots. Radio navigation signals can produce significant
       errors under some circumstances and the autopilot cannot detect this
       situation.
     · Make sure that all members of crew are familiar with the procedures
       to disengage the autopilot.
        Your Raymarine autopilot will add a new dimension to your boating
        enjoyment. However, it is the responsibility of the skipper to ensure
        the safety of the vessel at all times by careful observance of these
        basic rules.

        EMC Conformance
        All Raymarine equipment and accessories are designed to the best
        industry standards for use in the leisure marine environment.
        Their design and manufacture conforms to the appropriate
        Electromagnetic Compatibility (EMC) standards, but good
        installation is required to ensure that performance is not
        compromised.

Chapter 1: Introduction
                             1.1 Overview
                             The ST600R is a SeaTalk® compatible autopilot control unit. It is
                             designed for use as a repeater in an autopilot system, allowing

      Changing Course in Auto Mode
    · The +1 and +10 (starboard) and ­1 and ­10 (port) keys are used to
      change the locked heading, in increments of 1° and 10°, when the
      autopilot has control.
      Example: a 30° course change to port = press ­10 three times.




      Dodging Obstacles in Auto Mode
      Select a course change in the appropriate direction, for example,
      port 30° = -10 three times.




    · When safely clear of the obstacle, you can reverse the previous
      course change (for example, press +10 three times), or return to the
      previous locked heading (LAST HDG).

                         example, executing a dodge manoeuvre or selecting Standby) you
                         can return to the previous locked heading as follows:
                    1. Press AUTO for 1 second. The previous locked heading (LAST
                       HDG) is displayed for 7 seconds and the display flashes.
               Note: A direction-to-steer indicator is displayed to show you the direction
                     the vessel will turn.
                    2. To accept this heading, and resume the original course, press AUTO
                       once within this 7 second period.




                         If you do not press AUTO while the display is flashing, the current
                         heading will be maintained.

       Automatic Tack (AutoTack)
       The autopilot has a built in automatic tack facility that turns the
       vessel through a predetermined angle (the factory default, set in
       Dealer calibration, is 100°) in the required direction.

                         Off Course Alarm
                         The off course alarm sounds if the locked autopilot heading and the
                         vessel's current heading differ for more than 20 seconds, and by
                         more than the alarm angle set in calibration (the factory default
                         is 20°).




                    1. To cancel the off course alarm, press STANDBY to return to hand
                       steering.
                    2. Make sure your vessel is not carrying too much sail or the sails are
                       badly balanced. Significant improvements in course keeping can
                       usually be obtained by improving sail balance.

                         Making Major Course Changes
                     · It is sound seamanship to make major course changes only when
                       steering manually.
                     · Manual course changes ensure that obstructions or other vessels are
                       cleared properly, and due account taken of the changed wind and sea
                       conditions on the new heading prior to engaging the autopilot.
                         Course Changes Under Autopilot Control
                         It is important to understand the effect of sudden trim changes on
                         steering performance. When a sudden trim change occurs, due, for
                         example, to weather helm or sail imbalance, there will be a delay
                         before the automatic trim applies rudder to restore the locked
                         heading. This correction can take up to one minute.
                         Large course changes, which change the apparent wind direction,
                         can produce large trim changes. In these situations, the autopilot will
                         not immediately assume the new automatic heading, and will only
                         settle onto course when the automatic trim has been fully
                         established.

         for large course changes:
     1. Note the required new heading.
     2. Select STANDBY and steer manually.
     3. Bring the vessel onto the new heading.
     4. Select AUTO and let the vessel settle onto course.
     5. Bring the vessel to the final course with 1° increments.

         Gusty Conditions
         In gusty conditions, the course may tend to wander slightly,
         particularly if the sails are badly balanced. Significant
         improvements in course keeping can always be obtained by
         improving sail balance. Bear in mind the following important
         points:
      · Do not allow the yacht to heel over excessively
      · Ease the mainsheet traveller to leeward to reduce heeling and
        weather helm
      · If necessary, reef the mainsail a little early
         It is also advisable, whenever possible, to avoid sailing with the
         wind dead astern in very strong winds and large seas.
         Ideally, the wind should be brought at least 30° away from a dead
         run and, in severe conditions, it may be advisable to remove the
         mainsail altogether and sail under headsail only.
         Provided these simple precautions are taken, the autopilot will be
         able to maintain competent control in gale force conditions.

         2.4 Manual Mode
         If your system is fitted with a joystick, the ST600R will enter
         Manual mode when the joystick is in use.
         The ST600R will return to Standby mode when the joystick button
         is released, or if you press the STANDBY key on the ST600R.

Chapter 3: Advanced Operation
             This chapter provides information on:
          · Operation in Track mode
          · Operation in Vane mode (WindTrim)
          · Adjusting response and rudder gain
          · Alarms

             3.1 Operation in Track Mode
             Track mode is used to maintain a track between two waypoints
             created on a GPS, Decca, or Loran navigation system. The autopilot
             will then compute any course changes to keep your boat on track,
             automatically compensating for tidal streams and leeway.
             The autopilot can receive cross track error (the distance your vessel
             is from a planned track) from a SeaTalk navigation instrument or
             chartplotter
             Track mode is selected by pressing the TRACK key, but can only be
             selected in Auto mode. You can return to either Auto or Standby
             from Track as follows:
          · Press AUTO to leave Track mode and return to Auto mode.
          · Press STANDBY to leave Track mode and return to manual
            steering.

             Initiating Track Mode
             When initiating Track mode, the track can be acquired in one of two
             ways:
          · Automatic acquisition ­ when cross track error and bearing to
            waypoint data are available
          · Manual acquisition ­ when cross track error is the only available
            data
Chapter 3: Advanced Operation                                                              15




                        Automatic Acquisition
                        Automatic acquisition can only be achieved if the pilot is receiving
                        cross track error and bearing to waypoint information (via SeaTalk
                        or NMEA 0183). It is initiated as follows:
                   1. Bring the vessel to within 0.1nm of track
                   2. Press AUTO.
                   3. Press TRACK to enter Track mode, with the current locked heading
                      displayed.
                        After a short delay for data acquisition, the Waypoint Advance
                        alarm will sound, and the display will show the planned bearing to
                        waypoint alternating with the direction in which the boat will turn.



                                                                  STBD




                                                                        track




              Note: If the vessel is further than 0.3nm from the track, the Large Cross
                    Track Error alarm will sound. Press STANDBY to cancel the alarm,
                    hand steer closer to the track, and press AUTO and TRACK again.
                   4. Check that it is safe to turn onto the new course.
                   5. Press the TRACK key. The boat will turn on to the new course and
                      the alarm will be cancelled.

           · The display shows the new bearing to waypoint.

              Manual Acquisition
              For manual track acquisition when cross track error is the only data
              available:
          1. Steer the vessel to within 0.1nm of track.
          2. Bring the heading to within 5° of the bearing to the next waypoint.
          3. Press AUTO.
          4. Press TRACK to enter Track mode.
           · The display shows the cross track error and the locked pilot heading.
     Note: At low speeds, the effect of tidal streams is far more significant than it
           is at higher speeds. Providing the tidal flow is less than 35% of the
           vessel's speed, no noticeable difference should occur in the
           performance of Track mode. However, extra care should be taken
           during manual acquisition, as follows:
           · Ensure that the vessel is as close as possible to track, and the
             direction made good over the ground is as close as possible to the
             direction of the next waypoint, before selecting Track mode.
           · Make positive positional checks at regular intervals, especially if
             navigational hazards are close by.

                        Cross Track Error
                        Cross track error (XTE) is the distance between the current position
                        and a planned route. This is displayed in nautical miles (nm), statute
                        miles (SM) or kilometres, and is taken directly from your navigator.




                        The Large Cross Track Error alarm sounds if the cross track exceeds
                        0.3nm.

                    · The direction of the error is identified as "Pt" port or "Stb"
                      starboard.
                    · To cancel the alarm, press STANDBY to return to hand steering, or
                      AUTO to return to Auto mode.
              Note: If the Large Cross Track Error alarm sounds, it is usually an indication
                    that the cross tide is too great for the vessel's current speed.

     Tidal Stream Compensation
     Under most conditions, Track mode will hold the selected track to
     within ±0.05nm (300ft) or better.
     The autopilot takes account of vessel speed when computing course
     changes to ensure optimum performance over a wide range of vessel
     speeds. If speed data is available, the autopilot uses the measured
     vessel speed. Otherwise, the Speed Over Ground (SOG) or specified
     cruise speed is used, depending on the calibration setting (see
     "Dealer Setup" in Chapter 5).

     Waypoint Arrival and Advance
     If your navigation receiver transmits valid NMEA waypoint number
     and bearing to waypoint data, it is possible to advance from one
     waypoint to the next by simply pressing TRACK.

     Arrival
     As the vessel passes the target waypoint, the navigation receiver
     should select (manually or automatically) the next target waypoint.
     The autopilot detects the new target waypoint number, sounds the
     Waypoint Advance alarm and displays the Waypoint Advance
     information. This display shows the new bearing to waypoint and
     the direction the boat will turn to acquire the new track.
     To accept the new target waypoint, press TRACK.

                        Skipping a Waypoint ­ SeaTalk Navigators Only
                        If you wish to advance to the next waypoint before you have arrived
                        at the target waypoint, press TRACK for 1 second. The Waypoint
                        Advance information for the next waypoint is displayed.

                        Advance
                        While the waypoint advance alarm is sounding, Track mode is
                        suspended and the autopilot maintains the current boat heading.
                   1. Check that it is safe to turn onto the new track.
                   2. Press the TRACK key. This will cancel the waypoint arrival alarm
                      and turn the boat towards the next waypoint.
                        Unless the Waypoint Advance is accepted in the above manner, the
                        alarm will continue to sound and the current heading will be
                        maintained.

                        Dodges
                        Full control is still available from the keypad when the autopilot is in
                        Track mode.

                        Initiating a Dodge Manoeuvre
                        In track mode, dodge manoeuvres are accomplished by simply
                        selecting the desired course change using the course change keys
                        (-1, +1, -10 or +10).

                        Cancelling a Dodge Manoeuvre
                        Once the hazard has been avoided, the course change selected for
                        the dodge manoeuvre should be cancelled by selecting an equal
                        course change in the opposite direction.
              Note: Provided the vessel remains within 0.1nm of track, there is no need to
                    steer back towards the track.

                        Safety
                        Passage making in Track mode removes the chores of compensating
                        for wind and tidal drift, and will aid precise navigation. However, it
                        is important to maintain an accurate log with regular plots.

                        Position Confirmation at the Start of a Passage
                        At the start of a passage you must always confirm the fix given by
                        the position transducer, using an easily identifiable fixed object.
                        Check for fixed positional errors and compensate for them.

        Verifying Computed Positions
     · Verify the computed position with a dead reckoned position,
       calculated from the average course steered and the distance logged.

        Plot Frequency
     · In open water, plots should be at least hourly.
     · In confined waters, or when potential hazards are near, plots should
       be more frequent.
     · Local variations in radio signal quality, and changes in the tidal
       stream, will produce deviations from the desired track.

        Setting Waypoints
     · When setting waypoints, remember that deviations will occur.
     · Thoroughly check along each track.
     · Check up to 0.5nm each side of the track to ensure that there are no
       hazards within the zone.

        General
        The use of track mode will enable accurate track keeping even in
        complex navigational situations. However, it cannot remove the
        responsibility of the skipper to ensure the safety of his vessel at all
        times by careful navigation and frequent position checks.

        3.2 Operation in Vane Mode (WindTrim)
        Vane mode, also known as WindTrim, allows the autopilot to
        maintain a course relative to an apparent wind angle. It uses wind
        trim to eliminate the effects of turbulence and short term wind
        variations, and provides smooth precise performance under Vane
        mode operation with minimal power consumption.
        Vane mode uses the fluxgate compass as the primary heading
        reference and, as changes in the apparent wind angle occur, the
        locked compass heading is adjusted to maintain the original
        apparent wind angle.
        To use Vane mode, the autopilot must receive wind information
        from one of the following sources:
     · SeaTalk Wind instrument, connected to the autopilot via SeaTalk
     · NMEA wind information
     · Raymarine wind vane connected to a SeaTalk interface box
Chapter 3: Advanced Operation                                                               21




                        Selecting Vane Mode
                        Vane mode can be selected from either Standby or Auto modes, as
                        follows:
                   1. Steady the vessel onto a heading at which the apparent wind angle is
                      close to angle you require.
                   2. Press STANDBY and AUTO together to select Vane mode and
                      lock the current apparent wind angle.

                    · The locked heading is displayed in large characters. The locked
                      apparent wind angle is displayed above the heading, with an P (port)
                      or S (starboard) direction indicator.
                    · The boat heading is adjusted by the autopilot to maintain the locked
                      apparent wind angle.

                        Adjusting the Locked Wind Angle
                        The locked wind angle can be adjusted by changing course using the
                        -1, +1, -10 and +10 keys.
                        For example, to bear away by 10° when the vessel is on starboard
                        tack, press -10 to turn the vessel 10° to port. The locked apparent
                        wind angle and locked heading both change by 10°. The new
                        apparent wind angle is maintained, and the locked heading adjusted
                        by the autopilot as required.
              Note: This method does not apply to systems using the Type 100/300
                    Course Computer. Also, this method should only be used for minor
                    adjustments to the apparent wind angle, since turning the boat
                    affects the relationship between the true and apparent wind angles.
                    For major changes, return to Standby mode, steer onto the new
                    heading, and reselect Vane mode.

         Returning to the Previous Apparent Wind Angle
         (LAST WND)
         If for any reason the vessel is steered away from the selected
         apparent wind angle (for example, a dodge manoeuvre or selecting
         Standby) you can return to the previous locked wind angle:
     1. Press STANDBY and AUTO together for 1 second to display the
        previous apparent wind angle (LAST WND).

                                                                        DXXXX-1


         The LAST WND? text alternates with the previous wind angle and
         direction. The previous locked heading is displayed, with an
         indicator to show you the direction in which the vessel will turn.
     2. Check that it is safe to turn on to this course.
     3. To accept this apparent wind angle, press STANDBY and AUTO
        together within 7 seconds.
         If you do not accept the previous wind within this time, the autopilot
         will lock on to the current apparent wind angle.

         Dodges
         Full control is still available from the keypad when the autopilot is in
         Vane mode.
      · Dodge manoeuvres are accomplished by simply selecting the
        desired course change using the course change keys
        (-1, +1, -10 or +10). Both the locked heading and locked apparent
        wind angle are adjusted.
      · Once the hazard has been avoided, you can reverse the previous
        course change, or return to the previous apparent wind angle
        (LAST WND).

                        Wind Shift Alarm
                        The wind shift alarm sounds, and the text "WINDSHIFT" is
                        displayed, if a wind shift of more than 15° is detected.
                    1. Press STANDBY to cancel the alarm and return to hand steering,
                       and steer onto the required heading.
                    2. Press STANDBY and AUTO together to return to Vane mode with
                       the new apparent wind angle.

                        Using AutoTack in Vane Mode
                        The automatic tack function, when used in Vane mode, turns the
                        vessel so that the locked apparent wind angle is changed to an equal
                        angle on the opposite bow.
                        Initially, the autopilot turns the vessel through the specified tack
                        angle (the factory default is 100°). Then the locked heading is
                        adjusted until the required apparent wind angle is achieved.
                    · To tack to starboard, press the +1 and +10 keys together.
                    · To tack to port, press the -1 and -10 keys together.
              Note: If you use the Autotack function in Vane mode, it is important to check
                    that the wind vane has been centred accurately when it was installed.
                    Also, the AutoTack feature cannot be adjusted if you are using a
                    Type 100/300 Course Computer.

        Operating Hints
     · Major changes to the selected apparent wind angle should be made
       by returning to Standby mode, changing course manually, then
       reselecting Vane Mode.
     · Vane mode filters the windvane output. This provides the optimum
       response for off-shore conditions where genuine shifts in wind
       direction occur gradually.
     · In gusty and unsteady inshore conditions, it is best to sail a few
       degrees further off the wind so that changes in apparent wind
       direction can be tolerated.
     · It is important to ensure that the amount of standing helm is
       minimised by careful sail trimming and positioning of the mainsheet
       traveller.
     · The headsail and mainsail should be reefed a little early rather than
       too late.

                        3.3 Adjusting Autopilot Performance
                        The response level and rudder gain can be adjusted during normal
                        operation using a combined key-press.
                        The default calibration settings for response and rudder gain (refer to
                        Dealer Setup) are restored when the system is powered on.

                        Changing the Response Level (Auto Seastate)
                        The response level controls the relationship between the autopilot's
                        course keeping accuracy and the amount of helm/drive activity.
                    · Response Level 1, Auto Seastate (Automatic Deadband), causes the
                      autopilot to gradually ignore repetitive movements of the vessel and
                      only react to true variations in course. This provides the best
                      compromise between power consumption and course keeping
                      accuracy, and is the default calibration setting.
                    · Response Level 2 (Minimum Deadband) provides the tightest
                      course keeping possible. However, tighter course keeping results in
                      increased power consumption and drive unit activity.
                    · Response Level 3 (also Minimum Deadband) provides the tightest
                      course keeping possible by introducing yaw damping (requires a
                      rate gyro and is only available with course computer systems).
                        The response can be changed at any time. To do so:
                   1. Press the +1 and -1 keys together momentarily to display the
                      Response screen.
                   2. Press +1 or -1 to change the response level.
                   3. Wait for 5 seconds, or press      , to return to the previous display.

                Changing the Rudder Gain
                Press the +1 and -1 keys together for 1 second to display the Rudder
                Gain screen, and adjust the setting in the same way as for the
                response level. Refer to Chapter 7, "Post Installation Procedures",
                for instructions on how to check that the rudder gain is set correctly.
     Warning:   It is important that the rudder gain is correctly set on planing
                craft. Incorrect adjustment will lead to poor steering
                performance and is dangerous at high speeds.

                        SeaTalk Failure
                        This silent alarm indicates that there is a wiring fault in the SeaTalk
                        connection.

                        No Link
                        This silent alarm indicates that there is no link between the ST600R
                        and the course computer.

                        Auto Release
                        The Auto Release alarm is activated when an Raymarine stern drive
                        actuator is returned to manual steering.

                        Off Course
                        This alarm is activated when the vessel has been off course from the
                        locked heading by more than the specified angle for more than 20
                        seconds (see Section 2.3, "Using Auto Mode").
                        The alarm is cleared if the heading recovers or the course is
                        changed, or if the operating mode is changed.

                        Wind Shift
                        This alarm is activated when the apparent wind angle requires an
                        adjustment of the locked heading by more than 15° (see Section 3.2,
                        "Operation in Vane Mode").

                        Large Cross Track Error
                        This alarm is activated when the cross track error exceeds 0.3nm
                        (see Section 3.1, "Operation in Track Mode").
                        The autopilot stops controlling the locked heading as soon as this
                        condition occurs.
                        The alarm is cleared if the heading recovers or the course is
                        changed, or if the operating mode is changed.

             Drive Stopped
             This alarm is activated if the autopilot is unable to turn the rudder.
             This occurs if the weather load on helm is too high, or if the
             requested rudder position is past the preset rudder limits or the
             rudder end-stops.

             Data Not Received
             This alarm is displayed in the following circumstances:
          · Track mode is engaged and the autopilot is not receiving SeaTalk
            navigation data.
          · Track mode is engaged and the position transducer (GPS, Loran,
            Decca) is receiving a low strength signal ­ this will clear as soon as
            the signal strength improves.
          · Vane mode is engaged and the autopilot has not received wind angle
            data for 30 seconds.
             The autopilot stops adjusting the locked heading as soon as data is
             lost.

             Waypoint Advance
             The waypoint advance alarm sounds whenever the target waypoint
             number changes, which occurs in the following circumstances:
          · Automatic acquisition is selected by pressing TRACK from Auto
            mode
          · Waypoint advance is requested by pressing TRACK for 1 second in
            Track mode (SeaTalk Navigators only).
             When the alarm sounds, the pilot continues on its current heading,
             but displays the bearing to the next waypoint and the direction in
             which the boat will turn to take up that bearing.
             Check that it is safe to turn onto the new track, and press TRACK to
             accept the waypoint advance.
             To cancel the alarm without accepting the waypoint advance, press
             STANDBY to return to hand steering, or AUTO to return to Auto.
     Note: The waypoint advance will only operate on pilots receiving valid
           bearing to waypoint and waypoint number information.

Chapter 4: CodeLock
                         CodeLock is a personal four-digit security feature designed to
                         protect your valuable instruments against theft. You don't have to
                         activate the system, but it's there if you need to. You can activate it
                         using any CodeLock-compatible control unit on your SeaTalk
                         system.
                         When you first enter a code and activate CodeLock, the code is sent
                         to all the CodeLock-compatible units on the system. After this,
                         whenever you power on the system, the units will only start up if
                         they receive the correct code.
                         Remember to fix a CodeLock sticker by each instrument, to deter
                         potential thieves.

                         4.1 CodeLock Modes
                         When you set up CodeLock, you can choose whether the code will
                         be sent automatically or must be entered manually at power on, as
                         follows:
                      · Auto mode is used when there is a display unit situated in a secure
                        location, ideally below deck, or one which can be unplugged and
                        removed to a secure location. You enter your chosen code on this
                        "master" unit when you first activate CodeLock. This code is then
                        automatically sent to all CodeLock-compatible display heads on
                        SeaTalk, without further intervention, every time the system is

                      · Manual mode is used to provide a higher degree of security,
                        perhaps when all your instruments are mounted in exposed
                        locations. In this case, you must enter your personal code every time
                        the system is switched on. The code can be entered into any
                        convenient CodeLock-compatible control unit, and is then sent to all
                        the other compatible units via SeaTalk.

                         4.2 Setting Up CodeLock
                         CodeLock is set on the ST600R using the Intermediate Setup
                         options.

                         when a new code has been entered.

                          Changing the Code or Master Unit
                          You can change the code from any CodeLock compatible control
                          unit on your SeaTalk system, provided you know the current code.
             Note: If you set up CodeLock in Auto mode, the unit on which you enter the
                   new code becomes the new master unit.
                          To change the code:
                      1. Display the CodeLock entry screen and enter your current code, as
                         shown in the flowchart.
                          The code is checked. If it is incorrect, the four dashes are redisplayed
                          and you must enter the code again. If it is correct, the CodeLock
                          status screen is displayed, with the status set to OFF.
                      2. Press      to display the CodeLock entry screen again.
                      3. Enter the new code (as described in Initial Setup) and move on to the

                      4. Set the mode to Auto or Manual, as required.
                      5. Press and hold STANDBY for 2 seconds to exit Intermediate Setup
                         and save the new settings.

                          4.3 Entering Your Code (Manual Mode Only)
                          If CodeLock has been set up in Manual mode, the correct code must
                          be entered on one of the control units every time the system is
                          switched on. The code number created on the master is entered via
                          the keypad from any CodeLock-compatible instrument, and this
                          code is then sent to all compatible instruments on the same SeaTalk
                          bus. Once this code has been received the instruments operate in the
                          normal way.

Chapter 5: Customising the System
                       The ST600R provides setup and configuration options that are used
                       to adjust the settings for the ST600R itself, the compass, and the
                       autopilot.
              Note:    You should perform the post installation procedures described in
                       Chapter 7 before adjusting any other calibration features.
                       There are three setup levels:
                    · User Setup, which controls compass setup, rudder calibration and the
                      ST600R display features
                    · Intermediate Setup, which controls the CodeLock security feature
                      and displays status and version number information (see Chapter 4)
                    · Dealer Setup, which controls the autopilot settings, and also the
                      calibration lock which can be used to prevent accidental access to
                      User and Intermediate Setup
                       The Dealer Setup options described in this chapter only apply if you
                       have installed the ST600R as the control unit for a Type 100/300
                       course computer. If you have installed the ST600R as a repeater unit
                       on an autopilot system, please refer to the Dealer Setup instructions
                       in the handbook for the main control unit.

                       5.1 User Setup
                       The flow chart on the following page shows the User Setup control
                       procedure, and the setup screens with their default settings.
                       Information on the functions of the different settings is given in the
                       remainder of this section.
                       The following points should be considered:
                    · Make sure that the autopilot is in Standby mode before you access
                      User Setup
                    · If the CAL LOCK screen is displayed instead of the initial page, you
                      need to turn off the lock feature in Dealer Setup
                    · Setup options are always saved on exit

                       Compass Deviation Correction (SWING COMPASS)
                       The compass deviation correction option allows you to correct the
                       compass for deviating magnetic fields. The procedure must be
                       performed as the first item in your initial sea trial, and is described in
                       detail in Chapter 7, "Post Installation Procedures".

                       Deviation Display (DEVIATION)
                       This screen shows the current deviation value, calculated from the
                       correction procedure (Swing Compass). You cannot edit this value.

                       Heading Alignment (ALIGN HDG)
                       The heading alignment screen shows the current reported heading.
              Note:    You should always check the compass alignment after performing a
                       compass deviation correction (see "Post Installation Procedures").
                       However, once the initial correction procedure has been performed,
                       you can make adjustments to the alignment as often as you wish,
                       without re-correcting your compass.
                    · Steer onto a known heading, and check the heading displayed.
                    · If required, adjust the heading value to match the known value, using
                      the +1, -1, +10 and -10 keys.

                       Pilot Type*
                       Displays the Pilot Type: sterndrive, displacement, semi-
                       displacement or planing.

                       Heading Mode (HDG)
                       Select either magnetic or true heading mode, using the +1 or -1 key.
                       When heading data is displayed in normal operation, the screen
                       indicates whether true or magnetic mode has been selected.

                Rudder Calibration (DOCKSIDE RUDD CAL)*
                Dockside Rudder Calibration is used to automatically calibrate the
                rudder range (for systems with a rudder reference unit) and optimise
                autopilot performance by matching the autopilot to its installation.
     Warning:   This procedure moves the helm, and should only be used when
                the vessel is at the dockside. For sterndrive systems, the
                engines must be running before you start the procedure.
            · The auto dockside procedure is not available if the ST600R is used
              with a Type 100/300 Course Computer.
            · The Dock Side calibration feature is started using the +1 or -1 key.
            · If you start the procedure by mistake, press any key to cancel it.
            · If the autopilot does not respond, the display shows "AUTO N/A".
            · Activation and completion of Auto Dockside are displayed as:
              "AUTO WAIT" and "AUTO END" respectively.
            · The "ALIGN RUD" screen follows "AUTO END" if you have a
              rudder feedback transducer. The helm should be centred by hand and
              the rudder bar adjusted to zero using the -1 and +1 keys.

                       settings will provide safe performance for the initial sea trial, and fine
                       tuning is not normally required.
                       The flow chart on below shows you how to enter Dealer Setup, scroll
                       through the setup displays, adjust the values and exit.

                       Recommended Settings
                       The following pages list the default calibration settings for sailing/
                       power displacement and planing power vessels. Once you have set
                       the Pilot Type, these will provide good performance for initial sea
                       trials and can be fine tuned later to optimise performance.
                       After initial calibration has been carried out, further adjustment can
                       be made at any time.
                       The features that can be adjusted are listed in the table at the end of
                       this chapter, where you can record your settings for future reference.
                       Information on the functions of the different settings is given in the
                       remainder of this section.
                       The following points should be noted:
                    · Make sure that the autopilot is in Standby mode before you access
                      Dealer Setup
                    · Setup options are always saved on exit

                       Rudder Gain
                       This must be set while under way, as described in Chapter 7, "Post
                       Installation Procedures".
                        Range:                     1 to 9
                        Default:                   5   (Displacement)

                       Rate Level
                       Rate Level monitors the speed at which rudder is applied when
                       changing course. Rate level will, if the rate at which the vessel is
                       turning is too fast, counter this turn with opposite rudder.
                       The settings available are as follows:
                        Range:                     1 to 9
                        Defaults:                  7    Displacement

                       Rudder Offset
                       You only need to set this option if your system includes a rudder
                       reference unit.
                    · Manually place the helm in a central position. The reported rudder
                      angle is indicated on the rudder bar graphic at the bottom of the
                      screen.
                    · Adjust the offset value, using the +1 and -1 keys, until the rudder
                      position is shown as central on the rudder bar. The offset must be
                      within the range -7° to +7°.
                        Range:                     ­7° to +7°
                        Default:                   0

             Rudder Limit
             Rudder Limit restricts autopilot rudder movement to just less than
             the steering systems mechanical stops. This avoids putting the
             steering system under unnecessary load.
             The range available is as follows:
             Range:                     15° to 40°
             Defaults:                  30° Displacement, semi-displacement, planing
                                        20° Sterndrive




             Turn Limit
             This limits the rate of turn of your vessel when under autopilot
             control. The value must be within the range 5 to 20°. For sailboat
             applications it should be set to 20°.
             Range:                     5° to 20° per second
             Default:                   20° (Displacement)
                                        15° (Semi-displacement)
                                        08° (Sterndrive)

             Cruise Speed
             The Cruise Speed value is used by the autopilot during Track mode
             operation, when it calculates compensation for tidal streams and
             leeway.
             Set the value to the boat's normal cruising speed.
             Alternatively, set Cruise Speed to Auto mode (A) (not available when
             using a Type 100/300 Course Computer) so that Speed Over Ground
             (SOG) data is used, if available. SOG will normally give better course-
             keeping than a fixed value. However, using SOG could cause
             problems at low boat speeds where the tide exceeds 35% of the boat
             speed.
     Note:   If boat speed data is available via SeaTalk or NMEA, the Cruise
             Speed setting is ignored and the actual boat speed is used.
             Range:                     4 to 60 knots
             Defaults:                  6 (Displacement)
                                        8 (Semi-displacement)
                                        20 (Planing)
                                        20 (Sterndrive)

                       Off Course Alarm
                       This is the off course alarm angle. It controls the alarm that warns you
                       if the autopilot is unable to maintain its set course.
                       The alarm operates if the autopilot strays off course by more than the
                       alarm angle limit for more than 20 seconds.




                       The value must be within the range 15 to 40°, and can be adjusted in
                       1° steps.
                        Range:                        15 to 40°
                        Default:                      20°

                       AutoTrim
                       The AutoTrim level setting determines the rate at which the autopilot
                       applies "standing helm" to correct for trim changes caused by
                       varying wind loads on the sails or superstructure. The settings are:
                        Setting     Effect                        Recommended for:
                        1           Slow trim correction          Heavy displacement vessels,
                                                                  with full keel or transom rudder.
                        2           Medium trim correction        Heavy displacement vessels.
                        3           Fast trim correction          Moderate to light displacement
                                                                  vessels.

                        Default:                                  3

                       The default setting (Level 3) should provide optimum performance
                       with the ST600R autopilot. However, depending on the vessel's
                       dynamic stability, an incorrect rate of trim application may result in
                       poor course keeping due to autopilot instability.
46                                                      ST600R Autopilot Control Unit




        After gaining experience with the ST600R, you may wish to change
        the setting. The effect of the setting must be evaluated while under
        sail.
     · Decrease the AutoTrim level if the autopilot gives unstable course
       keeping or excessive drive activity with a change in the heel angle.
     · Increase the AutoTrim level if the autopilot reacts slowly to a
       heading change due to a change in the heel angle.
     · For systems without a rudder reference unit, these settings have no
       effect and trim is set to level 3.

        Power Steer
        Power steer selects the Joystick mode of operation: Proportional or
        `Bang-Bang'.
        Proportional applies rudder in proportion to Joystick movement ­
        the further the Joystick is held over the greater the applied rudder.
        Bang-Bang applies continuous rudder drive in the direction of lever
        movement. To improve control the speed of rudder movement
        changes with the angle of the lever. For maximum speed push the
        lever hardover. If the lever is returned to the centre position the rudder
        will remain in its current position.
        The settings available are as follows:
        Range:                       1 = Proportional
                                     2 = Bang-bang
        Default:                     1

        Drive Type
        The drive type controls the way which the autopilot drives the
        steering system. The default setting should be retained for
        mechanically driven vessels.
        Range:          1 = Mechanically driven vessels without a rudder reference unit
                        2 = Hydraulic, no rudder reference unit
                        3 = Linear, rotary and sterndrive with a rudder reference unit
                        4 = Hydraulic with rudder reference unit
        Default:        1

                       Rudder Damping
                       You only need to set this option if your system includes a rudder
                       reference unit, and the drive "hunts" when trying to position the
                       rudder. Test for this when your vessel is moored dockside, by
                       pressing AUTO and then +10. If the helm overshoots and has to drive
                       back or starts to hunt back and forth, you need to increase the
                       damping level.
                       In auto mode (A), the autopilot applies damping compensation
                       automatically ­ not available if using a Type 100/300 Course
                       Computer.
                       Alternatively, you can set a value in the range 1 to 9. Adjust the
                       damping one level at a time, and always use the lowest acceptable
                       value.
                        Range:                     1 to 9
                        Default:                   1

                       Variation
                       If required, set this value to the level of magnetic variation present at
                       your vessel's current position. +ve variation = East, -ve variation =

             AutoAdapt




             The patented AutoAdapt feature allows the autopilot to compensate
             for heading errors at higher latitudes, which are caused by the
             increasing dip of the earth's magnetic field. The increased dip has the
             effect of amplifying rudder response on northerly headings in the
             northern hemisphere, and on southerly headings in the southern
             hemisphere.
             Set AutoAdapt to "nth" in the northern hemisphere, or "sth" in the
             southern hemisphere. You then need to enter your current latitude in
             the next setup screen, so that the autopilot can provide accurate
             course keeping by automatically adjusting the rudder gain
             depending on the heading.
             Range:                       0ff = Off

             Latitude
             This screen is only used if AutoAdapt is set to North or South.
             Use the +1, -1, +10, and -10 keys to set the value to your vessel's
             current latitude, to the nearest degree.

                       Auto Tack*
                       The AutoTack angle is the angle through which the vessel will turn
                       when the automatic tack feature is selected. The value must be within
                       the range 40 ~ 125° and can be adjusted in 1° steps.

                          The ST600R remote unit is connected directly to Raymarine
                          autopilots or instruments using the Raymarine data interface system
                          (SeaTalk bus).
                          The ST600R is supplied with a waterproof plug and socket (deck
                          connector) that can be installed anywhere a remote is required. The
                          deck connector allows you to make connections directly to the
                          autopilot, or any SeaTalk instrumentation, and can be connected in-
                          line or as a spur (see below).

        This chapter describes the following:
     · Planning the installation, including choosing the connection cable
     · Determining the connections for your autopilot
     · Mounting the bulkhead socket
     · Installing the bulkhead bracket

        6.1 Planning the Installation
        This chapter explains how to install the ST600R autopilot control
        unit. Before you start, obtain the correct connection cable, and decide
        how you will site the unit and run the cables.

        Choosing the Correct Connection Cable
        Because the range of Raymarine autopilots is extensive, the cable
        used to connect the ST600R must be ordered separately (see below).
        Part Number            Cable Description
        D131                   Round connectors at both ends, 9m (29ft. 3in.)
        D177                   No plugs but fitted with an in-line 5A fuse,
                               3m (9ft. 9in.)

        Q018                   SeaTalk cable (no plugs) sold by the 0.3m (1ft)

        Cabling Guidelines
     · Avoid running cables through bilges where possible
     · Secure coiled lengths at regular intervals
     · Avoid running cables close to fluorescent lights, engines, radio
       transmitting equipment etc
Chapter 6: Installation                                                                                53




                             EMC Installation Guidelines
                             The design and manufacture of Raymarine equipment and accessories
                             conforms to the appropriate Electromagnetic Compatibility (EMC)
                             standards, but good installation is required to ensure that
                             performance is not compromised.
                             To avoid the risk of operating problems, all Raymarine equipment and
                             cables connected to it should be;
                          · At least 1m (3 feet) from any equipment transmitting or cables
                            carrying radio signals e.g. VHF radios, cables and antennas. In the
                            case of SSB radios, the distance should be increased to 2m (7ft).
                          · More than 2m (6ft) from the path of a radar beam. A radar beam can
                            normally be assumed to spread 20 degrees above and below the
                            radiating element.
                          · The equipment should be supplied from a different battery than the
                            one used for engine start. Voltage drops below 10v in the power
                            supply to our products can cause the equipment to reset. This will
                            not damage the equipment, but will cause the loss of some
                            information and can change the operating mode.
                          · Genuine Raymarine cables should be used at all times. Cutting and
                            rejoining these cables can compromise EMC performance and so
                            should be avoided unless doing so is detailed in the installation
                            manual.
                          · If a suppression ferrite is attached to a cable, this ferrite should not
                            be removed. If the ferrite has to be removed during installation it
                            must be reassembled in the same position.
                             If your Raymarine equipment will be connected to other equipment
                             using a cable not supplied by Raymarine, a suppression ferrite MUST
                             always be fitted to the cable close to the Raymarine unit.
                             The following illustration shows the range of suppression ferrites
                             fitted to Raymarine equipment.

       6.2 Connections
       The cable connections depend on the autopilot to which you are
       connecting the remote unit. The following sections show the
       connections required for:
     · ST1000 and ST2000 Plus autopilots
     · ST4000 Plus and ST5000 Plus autopilots
     · ST6000 Plus control unit
     · Type 100/300 Course Computer
       If you have purchased SeaTalk cable fitted with connectors at both
       ends, one of these connectors will have to be removed, and the bare
       end stripped back to reveal the red, yellow and screen wires.

       ST1000 and ST2000 Plus Autopilot Connections
       The ST600R can also be connected to any available SeaTalk
       instrument as well as the autopilot. For details of the pin connections,

                            This shows that the control head is active. If the unit does not beep,
                            check the fuse/circuit breaker.
                            If "NO LINK" is displayed, check the link between the ST600R
                            control head and the Course Computer.

                            SeaTalk Interface
                            If the ST600R is linked to other SeaTalk instruments via SeaTalk, the
                            link can be checked as follows:
                      1. Press STANDBY.
                      2. Select display illumination level 3 on any other SeaTalk instrument
                         or autopilot control unit.

     The ST600R should immediately respond by switching on its display
     illumination.
     If the illumination does not switch on, a cabling fault exists in the
     SeaTalk cabling between the ST600R control head and the
     instruments/control unit.

Chapter 7: Post Installation Procedures
                          This chapter applies to systems where the ST600R has been
                          installed as the only control unit for a Type 100/300 Course
                          Computer.
                          Once you have installed the system, you need to confirm that it is
                          wired correctly and is also set up to suit your type of boat.
                          This chapter provides instructions for the following procedures:
                      · Functional test, consisting of a few simple tests to confirm that the
                        system is wired correctly
                      · Initial sea trial, to swing the compass and align the heading, check
                        the autopilot's operation and check the rudder gain
                          Further customisation can be performed after the sea trial, as
                          described in Chapter 5.

                          7.1 Functional Test and Initial Calibration
                          Switch On
                          Once you have installed your ST600R system, switch on the main
                          power breaker. If the control head is active and the system operating,
                          the following will occur:
                      · The control head beeps and displays the pilot type as ST600R.
                          This shows that the control head is active.
                      · If the head does not beep, check the fuse/circuit breaker.
                      · If the SEATALK FAIL alarm is displayed, check the SeaTalk
                        connections.

         Operating Sense
         The operating sense defines the direction the helm will be applied
         when a course change key is pressed or the vessel goes off course.
         Check the operating sense as follows:
     1. Press AUTO.
     2. Press the +10 key. The helm should move to produce a turn to
        starboard.

     3. If the helm produces a turn to port, reverse the motor connections at
        the course computer.
     4. If the helm overshoots and has to drive back or starts to hunt back
        and forth, you need to increase the Rudder Damping option in
        Dealer Setup (see Chapter 5).

         Navigation Interface (GPS, Decca, Loran)
         If the course computer is interfaced to a navigator, via an NMEA
         data port, the interface can be checked by displaying the Data Pages.
         Press      to display the first chapter heading. After 2 seconds, the
         first data page in this chapter is displayed. Press    to check each
         successive page.
         If dashes are displayed instead of data values, the cause could be one
         or more of the following:
      · A cabling error. Check for an open circuit, short circuit or reversed
        wires.
      · The navigator is not configured to transmit the required data format.
      · The signals being received by the navigator are too weak for reliable
        navigation. Refer to the navigator handbook for further action.

                          Wind Transducer Interface
                          If the course computer is connected to a wind instrument via an
                          NMEA port or SeaTalk, then the link between the two instruments
                          should be checked as follows:
                          Press STANDBY and AUTO together.
                          The ST600R should display the Vane mode screen, with the locked
                          wind angle and locked heading as shown.

                          EMC Conformance
                          The design and manufacture of Raymarine equipment and
                          accessories conforms to the appropriate Electromagnetic
                          Compatibility (EMC) standards, but good installation is required to
                          ensure that performance is not compromised. Although every effort
                          has been taken to ensure that they will perform under all conditions,
                          it is important to understand what factors could affect the operation
                          of the product.
                          Always check the installation before going to sea to make sure that it
                          is not affected by radio transmissions, engine starting etc..
                          In some installations, it may not be possible to prevent the
                          equipment from being affected by external influences. In general
                          this will not damage the equipment but can lead to it resetting, or
                          momentarily may result in faulty operation.

                   7.2 Initial Sea Trial
                   Having checked that the system is functioning correctly, a short sea
                   trial is now required to complete the setup. It involves the following
                   procedures:
                · Automatic compass deviation correction
                · Heading alignment adjustment
                · Autopilot operation check
                · Rudder gain adjustment
                   The initial sea trial should be performed in the following
                   circumstances:
                · After all the installation, functional test and initial calibration have
                  been completed successfully
                · Before any other changes have been made to the default calibration
                  settings: check and, if necessary, reset the values to the
                  recommended levels, as described in Chapter 5
                · In conditions of light wind and calm water, so that autopilot
                  performance can be assessed without the influence of strong winds
                  or large waves
                · In waters clear of any obstructions
        Note: At any time during the sea trial you can press STANDBY to return to
              hand steering.

                   Automatic Compass Deviation Correction
                   The autopilot will correct the fluxgate compass for most deviating
                   magnetic fields. Compass errors due to deviating magnetic fields
                   can be as great as15° or even 45°, depending on your vessel type.
                   The correction procedure reduces these to a few degrees, so it is
                   essential to perform the procedure as the first item in your initial sea
                   trial.
     Caution:      Failure to carry out the deviation correction may result in impaired
                   autopilot performance on some compass headings.
                   To allow the system to determine the deviation and calculate any
                   correction required, you must turn your vessel in slow circles. This
                   procedure must be carried out in calm conditions and preferably in
                   flat water.

                          To perform the deviation correction:
                     1. Make sure that the autopilot is in Standby mode with the drive unit
                        engaged.
                     2. Press and hold the STANDBY key for 2 seconds to display the User

         5. Keeping the boat speed below 2 knots, turn the vessel in slow
            circles. It should take at least 3 minutes to complete 360°.




         6. Keep turning your boat until the unit beeps and the Deviation screen
            is displayed.
             This shows the maximum deviation detected, and indicates that
             compass correction has been completed successfully.
     Note: If the deviation value exceeds 15°, you should consider moving the
           fluxgate compass to a better location.
         7. Press the        key to move on to the Heading Alignment page.
         8. Use the +1 and -1 keys, or the +10 and -10 keys, to increase or

                     9. Press and hold STANDBY for 2 seconds to exit calibration and save
                        the new settings.
               Note: Setup options are always saved on exit.

                          Further Heading Alignment Adjustment
                          You should always check the compass alignment after swinging the
                          compass. However, once the initial deviation correction procedure
                          has been performed, you can make adjustments to the alignment as
                          often as you wish, without swinging the compass again.
                          Although the compass deviation correction procedure removes most
                          of the alignment error, you will probably be left with small errors (of
                          the order of a few degrees) that will vary depending on the heading.
                          Ideally, you should check the heading reading against a number of
                          known headings, plot a deviation curve, and determine the heading
                          alignment value that will give the lowest average alignment error.
                          This value can then be entered on the Heading Alignment screen, as
                          described above.
                          If the average heading error is more than 5°, you should perform the
                          compass deviation correction procedure again.

                          Checking Autopilot Operation
                          Having calibrated the compass the following procedure is
                          recommended to familiarise yourself with autopilot operation:
                     1. Steer onto a compass heading and hold the course steady.
                     2. Press AUTO to lock onto the current heading. A constant heading
                        should be achieved in calm sea conditions.
                     3. Use the -1, -10, +1 and +10 keys to alter course to port or starboard
                        in multiples of 1° and 10°
                     4. Press STANDBY and disengage the autopilot to return to hand
                        steering.

         Checking the Rudder Gain
         The factory setting for rudder gain will provide stable control for
         initial sea trials. However, vessels can vary widely in their response
         to the helm, and further adjustment to the rudder gain may improve
         the autopilot's steering characteristics.
         It is important to ensure that rudder gain is set correctly on high-
         speed craft. Incorrect adjustment will lead to poor steering
         performance and is dangerous at high speeds.
         The following test will determine whether the rudder gain is set too
         high or too low.
     1. In clear water and with the autopilot in Auto, alter course to
        starboard by 40° by pressing the + 10 key four times.
      · At cruising speeds, course changes of 40° should result in crisp turns
        followed by an overshoot of no more than 5°. If this occurs the
        rudder gain is adjusted correctly.
      · An excessively high rudder setting results in oversteer. This is
        recognised by a distinct overshoot of more than 5° (A). This
        condition can be corrected by reducing the rudder gain setting.
      · Similarly, an insufficient rudder control setting will result in
        understeer which gives sluggish steering performance (B). If the
        vessel takes a long time to make the turn and there is no overshoot
        then the rudder setting is too low.
Chapter 7: Post Installation Procedures                                                      69




                          These actions are most easily recognised in calm sea conditions
                          where wave action does not mask basic steering performance.
                     2. Refer to Chapter 5, "Customising the System", for instructions on
                        how to adjust the default rudder gain setting. Note that you can also
                        make temporary adjustments to rudder gain during normal operation
                        (see Section 3.3).
                     3. Repeat the test until a crisp course change with no more 5° of
                        overshoot is achieved.
                          The rudder control setting should be set to the lowest setting
                          consistent with accurate course keeping. This will minimise helm
                          movements and hence reduce power consumption and wear and
                          tear.

Chapter 8: Maintenance
                         General
                    · In certain conditions, condensation may appear on the LCD
                      window. This will not harm the unit, and can be cleared by
                      switching on the illumination for a while.
                    · Never use chemical or abrasive materials to clean your autopilot. If
                      the pilot is dirty, wipe it with a clean, damp cloth.
                    · Periodically check the cabling for chafing or damage to the outer
                      casing ­ replace any damaged cables.

                         Servicing and Safety
                    · Raymarine equipment should be serviced only by authorised
                      Raymarine service engineers. They will ensure that service
                      procedures and replacement parts used will not affect performance.
                      There are no user serviceable parts in any Raymarine product.
                    · Some products generate high voltages, and so never handle the
                      cables/connectors when power is being supplied to the equipment.
                    · Always report any problem related to Electromagnetic
                      Compatibility (EMC) to your nearest Raymarine dealer. We will use
                      any such information to improve our quality standards.

                         Advice
                         Should any difficulties arise with this product, please contact the
                         Raymarine Product Support department in the UK, or your own
                         national distributor who will be able to provide expert assistance.
                         Before you consider returning the remote, make sure that the power
                         supply cable is sound and that all connections are tight and free from
                         corrosion.
                         If the connections are secure, refer to the Fault Finding chapter of
                         this handbook. If the fault cannot be traced or rectified, please
                         contact your nearest Raymarine dealer or Service Centre.
                         Always quote the product serial number, which is printed on the rear
                         cover, and the software version number, which is displayed when
                         you enter Intermediate Setup (see Chapter 5).

Chapter 9: Fault Finding
             All Raymarine products are subjected to a comprehensive test
             procedure prior to packing and shipping. In the unlikely event that a
             fault does occur with your autopilot, the following check list should
             help identify the problem and provide a cure.
             The display is blank
          · No power ­ check the fuse/circuit breaker.
             The display shows "CODE - - - -" at power on
          · The CodeLock code must be entered manually (see Chapter 4).
             The displayed compass heading does not agree with the
             ships compass
          · The compass has not been corrected for deviation ­ carry out the
            deviation and alignment procedures.
             Vessel turns slowly and takes a long time to come on to
             course
          · Rudder gain too low.
             Vessel overshoots when turning on to a new course
          · Rudder gain too high.
             The autopilot appears to be unstable in Track mode, or track-
             holding is slow
          · If tide speed exceeds 35% of boat speed, and boat speed is not
            available via SeaTalk, change the Cruise Speed setting in Dealer
            Setup from Auto (A) to the boat's cruising speed.
             The autopilot appears to be unstable on Northerly headings
             in the Northern hemisphere and Southerly headings in the
             Southern hemisphere
          · Northerly/Southerly heading correction not set up.
             Display shows CAL LOCK when entering calibration
          · Calibration locked out ­ calibration protection feature is turned on in
            Dealer Setup.
             The autopilot will not "talk" to other SeaTalk instruments
          · Cabling problem ­ make sure all the cables are connected properly.

                           Position information not received
                      · Navigator not transmitting the correct position data.
                           The autopilot will not auto advance to the next waypoint
                      · No bearing to waypoint information received from the navigator.
                           A series of rotating dashes are displayed on screen
                      · Compass deviation correction or dockside rudder calibration is
                        running.
                           The display shows a series of stationary dashes
                      · Data is not being received ­ check the cabling.
                           The display shows "NO DATA"
                      · The signals received from the navigator are too weak ­ refer to the
                        navigator handbook for further action.
                           Locked wind angle cannot be engaged or adjusted
                      · This feature is not available if you have a Type 100/300 Course
                        Computer running software prior to version 11.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
