Chapter 1: Description
1.1 SeaTalkng overview
      Introduction
      SeaTalkng is an interconnection bus for Raymarine products, and comprises a main
      backbone to which Raymarine products are connected via spur cables (see Figure
      1-1).

      Terminology
      Raymarine produces SeaTalk, SeaTalk2 and SeaTalkng proprietary bus systems. In
      this book, in the interests of clarity, SeaTalk is referred to as `SeaTalk(1)'.

      Connectability
      Specific Raymarine products (e.g. ST70 instruments) perform a bridging function, to
      enable you to connect SeaTalkng to SeaTalk(1) products via appropriate adaptor
      cables. Adaptor cables are also available to connect NMEA2000 products.

1.2 Hardware
      SeaTalkng comprises a single backbone terminated with two terminators, one at each
      end. Spur cables connect the backbone to individual SeaTalkng products.
      Small diameter cable connectors are used throughout the system, to make
      installation easier. Cables and connectors are color-coded to reduce the likelihood of
      misconnection.
      A wide range of different cable lengths provides flexibility and obviates the need for
      cutting and splicing cables.
      Three-way, five- way and in-line connection pieces are available to connect cables, to
      deploy SeaTalkng as required.
2                                                             SeaTalkng Reference Manual


       Color coding
       Cables and connectors are color-coded to facilitate correct connection. The color
       codes are:
        Backbone is blue.
        Spurs are white.
       A power cable is also provided and is color-coded with a red strip.

       Important: you must fit Terminators
       In order to ensure correct data transmission through a SeaTalkng system, a
       Terminator is required at each end of the backbone cable run. Dedicated
       Terminators are available for this purpose. Do NOT attempt to run a system that is
       not correctly terminated.

      Other cables
      In addition to the parts listed, a range of connector cables is available from your
      Raymarine dealer to connect to other Raymarine products and systems.

      Connectors
      SeaTalkng connectors are lockable to ensure reliable, secure connectivity. Keyways
      on the connectors ensure correct orientation. Locking collars on the SeaTalkng
      T-Piece, 5-Way Connector and Backbone Extender rotate to lock the connections.
      Molded arrow indicators on the connectors align to show when the connector is
      unlocked.


1.3 Using SeaTalkng
      A complete SeaTalkng backbone comprises two or more backbone cables connected
      in series. There must be only one backbone and this must be terminated with two ter-
      minators, one at each end of the backbone. Do NOT connect a terminator to any spur.
      In a SeaTalkng system and any system to which it is connected:
       As a general rule, there must only be one data source (transducer) for each data
           type. Although some products may be permitted as secondary data sources, do
           not duplicate the source for any data unless permission is specifically given in the
           relevant product documents.
       There must be only one power source.
      It is particularly important to be aware of these requirements when connecting to
      another system. For example, in Raymarine SeaTalk(1), power is often supplied from
      the system autopilot.
Chapter 1: Description                                                                                                                             5


      You can use SeaTalkng:
       As a self-contained system in which only products fitted with SeaTalkng
         connectors are connected via spur cables to the SeaTalkng backbone.
       As an extended system, connected to SeaTalk(1) products via an adaptor cable.
      You must NOT connect a SeaTalkng system to a SeaTalk2 system.
      You may connect specific SeaTalkng products (e.g. ST70 instruments) to existing
      SeaTalk(1) and SeaTalk2 systems, using the appropriate adaptor cables. Refer to the
      instructions with these products for details of how to connect them.
      As it is obviously not possible to describe all possible configurations for SeaTalkng,
      general guidelines, are given here.

      Typical applications
      A typical SeaTalkng system is shown in Figure 1-2. It comprises the main backbone,
      with compatible products connected via spur cables.

    General guidelines when using with other systems
    Basic rules
    If SeaTalkng is connected to any other system, ensure that in the combined system:
     You connect only one source for any data type, unless permission is specifically
        given in the relevant product documents.
     You connect only one power source.
    Limitations when SeaTalk(1) products are connected
    If SeaTalkng and SeaTalk(1) products are used together, do NOT connect an
    NMEA2000 backbone, as this product combination could compromise the integrity of
    the NMEA2000 system.
    Using with SeaTalk(1)
    Provided you do not want to connect to NMEA2000, you can connect a SeaTalkng
    system to SeaTalk(1) using a suitable SeaTalkng bridging product (such as an ST70
    instrument) and adaptor cables to connect the two systems.
    If you intend doing this, note that:
     You can connect a single SeaTalk(1) network to SeaTalkng using an adaptor cable
         and one bridging product (e.g. ST70 instrument).
     You can connect two separate SeaTalk(1) networks to SeaTalkng using different
         adaptor cables and bridging products (e.g. ST70 instruments), but the two
         SeaTalk(1) networks must NOT be connected together.
    Summaries of acceptable and unacceptable SeaTalkng/SeaTalk(1) scenarios are
    shown in Figure 1-3 and Figure 1-4 respectively.

Chapter 2: Installation
2.1 Preparation for installation
       EMC installation guidelines
       Raymarine equipment and accessories conform to the appropriate Electromagnetic
       Compatibility (EMC) regulations. This minimizes electromagnetic interference
       between equipment, which could otherwise affect the performance of your system.
       Correct installation is required to ensure that EMC performance is not compromised.
       For optimum EMC performance, we recommend that:
        Raymarine equipment and the cables connected to it are:
           At least 3 ft (1 m) 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 7 ft (2 m).
           More than 7 ft (2 m) 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 product is supplied from a separate battery from that used for engine start.
          This is important to prevent erratic behavior and data loss which can occur if the
          engine start does not have a separate battery.
        Raymarine specified cables are used.
        Cables are not cut or extended unless doing so is detailed in the installation manual.
       Remember
       Where constraints on the installation prevent any of the above recommendations,
       always allow the maximum separation possible between different items of electrical
       equipment.
       This will provide the best conditions for EMC performance for the installation.

       Suppression ferrites
       Raymarine cables may be fitted with suppression ferrites. These are important for
       correct EMC performance. Any ferrite removed to facilitate installation must be
       replaced in the original position immediately installation is complete.
       Use only ferrites of the correct type, supplied by Raymarine authorized dealers.

       Connections to non-Raymarine equipment
       If Raymarine equipment is to be connected to other equipment using a cable not
       supplied by Raymarine, a Raymarine suppression ferrite MUST always be attached
       to the cable near the Raymarine unit.

       Tools required
       Before installing SeaTalkng, ensure you have the appropriate tools. In most cases, a
       typical fitter's toolkit should suffice, provided it has tools to enable you to:
        Drill holes for cable runs.
        Connect prepared bare wire ends to terminal blocks.

     System structures
     Plan the route of the SeaTalkng backbone so that it runs as close as is practicable to
     the intended location of each SeaTalkng product, to keep spur lengths to a minimum.
     Products connect to the backbone via spur cables. Spurs connect to the backbone via
     either a SeaTalkng T-Piece or a SeaTalkng 5-Way Connector.

     Power supply considerations
     It is important that power for SeaTalkng is provided from only one power source. If you
     intend using your SeaTalkng system with any other system (e.g. SeaTalk(1)), power
     may already be connected to the other system. If this is the case, do NOT connect an
     additional power source to SeaTalkng.
     Product loading
     The number of products you can connect to a SeaTalkng system depends on the
     power each product consumes and on the physical length of the proposed system.
     Each Raymarine product has a Load Equivalency Number (LEN), which indicates
     how much power it consumes.
     Power sources
     A SeaTalkng system requires one 12 V dc supply, connected to the SeaTalkng
     backbone. This can be provided:
      By a battery.
      From a Raymarine Course Computer, via SeaTalk and/or SeaTalkng.
     Note: If a battery is used as a power source, it is recommended that in order to avoid sudden
     voltage drops, the battery used for engine starting is NOT used to power SeaTalkng.
     On boats with 24 V dc systems, a suitable 24 V to 12 V dc dropper may be used.
     Check with Raymarine Customer Support or your Dealer for suitability.
     Protection
     The power source must be protected by a 5 A fuse or a circuit breaker providing
     equivalent protection.
     Power connection point
     Balanced system
     We recommend that as a general rule, power is connected to a SeaTalkng system in
     such a way that the current drawn on each side of the power connection point, is
     equal.
     This is termed a balanced system.
     Figure 2-1, shows a theoretical balanced system. In this system the total LEN of the all
     products is 40, so the optimum power connection point is a total LEN value of 20 each
     end of the backbone.

       Figure 2-1 Where to connect SeaTalkng power in a balanced system
       Small systems
       Although the preferred method of connection is to form a balanced system as above,
       in systems where the backbone length is 60 m or less, you may connect power at one
       end of the system, to form an unbalanced system.
       Permitted power loading
       The total load permissible in a SeaTalkng system is defined in terms of the total LEN of
       all products connected to the system, and depends on the length of the backbone.
       Balanced system loading
       The maximum loading (total LEN) for balanced SeaTalkng systems of various lengths
       is given in the following table. Note that in each case, the total LEN must be
       divided equally each side of the power connection point.

     System limitations
     In a SeaTalkng system:
      The total length of backbone cable between the two Terminators must not exceed
         656 ft (200 m).
      The length of any individual spur must not exceed 16 ft 4 in (5 m).
      The total length of all spurs must not exceed 98 ft 5 in (30) m. So for example,
         your system could have 30 spurs, each of 3 ft 3 in (1 m), or 6 spurs each of
         16 ft 4 in (5 m).
      The total LEN in the system must not exceed the value detailed under Permitted
         power loading.

     Cabling
     When planning SeaTalkng cable routes (see Figure 2-2 and Figure 2-3), ensure that
     the EMC conditions are fulfilled (see EMC installation guidelines above). In particular,
     do not route cables near fluorescent lights, engines and radio transmitting equipment,
     as these may cause interference. Taking this into account, plan the backbone route to
     run as close as possible to the intended locations of the products to be connected.

       General requirements
       Use only the appropriate lengths of genuine Raymarine SeaTalkng made-up
       backbone and spur cables. Do NOT cut or otherwise modify the cables.
       To minimize the need to coil and stow spare cable, always use lengths of cable
       appropriate to the cable run lengths.

     Figure 2-4 Connecting cables
     Running cables
     When running SeaTalkng cables, always do so in accordance with the following
     guidelines:
      Do not run cables where they are likely to be easily damaged.
      If a cable has to be fed through the deck, always use a proprietary deck gland.
      Where cables are fed through holes (in bulkheads etc), always use the
        appropriate grommets to prevent chafing.
      Secure long cable runs so they do not present a hazard.
      Do not position cable connectors in bilges.
Chapter 2: Installation                                                                    15


       Installing Backbone
       Build the backbone by running backbone cables between the locations of the
       products you want to connect (spur points). At each spur point, connect the backbone
       cables to an appropriate SeaTalkng connecting device, either:
        T-Piece, part number A06028. Use where you want to connect a spur cable to just
           one product.
        5-Way Connector, part number A06064. Use where you want to connect more
           than one spur cable to products fitted close to one another (e.g. in the cockpit).
        Backbone Extender, part number A06030. Use as necessary, to connect lengths
           of backbone cable together.
       CAUTION: Backbone Extender
       The Backbone Extender A06030 is suitable only for connecting backbone
       cables. Do NOT attempt to use it to join spur cables, or damage could occur.

       Connecting spurs
       At each connecting device (T-Piece or 5-Way Connector), connect spur cables to the
       white connectors as required, then run each spur cable to the location of the product
       to be connected. Connect each spur cable to the relevant product in accordance with
       the installation instructions for the product.
       Where space is limited, e.g. behind instrument consoles, it may be easier to use an
       elbow spur cable rather than the conventional straight spur.

       Connecting power
       This section describes how to connect power to a stand-alone SeaTalkng system. If
       your SeaTalkng system is connected to any other system (e.g. another SeaTalk
       system) and the other system already has its own power source, do NOT connect
       another power source to SeaTalkng.
       CAUTION: Do not connect power until installation is complete
       Before connecting a power cable to the SeaTalkng backbone, ensure it is not
       connected to a power source.
       For optimum SeaTalkng performance, power must be connected in accordance with
       the conditions described under Power supply considerations on page 10. Whenever
       possible, connect your system as a balanced system.If it is not possible to do this and
       the SeaTalkng backbone is less than 197 ft (60 m) in length, you may connect the
       power source to form an unbalanced system.
       Ensure that the power source is protected by a 5 A fuse or a circuit breaker providing
       equivalent protection.
       Balanced system
       To connect power for a balanced SeaTalkng system:
       1. Determine the total LEN of the products in the system.
       2. Divide the total LEN by two and note the value.
16                                                                             SeaTalkng Reference Manual

     3. Starting at one end of the system, add the LEN of each product in turn, until you
        reach the value calculated at step 2. The point on the backbone between this
        product and the next is the point where the system load is evenly split.
     4. At this point fit a T-Piece A06028 then Connect a SeaTalkng Power Cable A06049
        to the white connector on the T-Piece. See Figure 2-5.
     5. Ensure the power supply is switched off then connect the power cable via a 5 A
        fuse or equivalent value circuit breaker, to the power supply.

     Figure 2-5 Connecting power to a balanced system
     Unbalanced system
     If the backbone is less than 197 ft (60 m), you can connect your power source to form
     an unbalanced system, as follows:
     1. At one end of the backbone fit a T-Piece A06028 then connect a SeaTalkng Power
        Cable A06049 to the white connector on the T-Piece.
     2. Ensure the power supply is switched off then connect the power cable via a 5 A
        fuse or equivalent value circuit breaker, to the power supply.

     Fitting Terminators
     When the backbone is in position, use a suitable connecting device (e.g. a T-Piece) to
     connect a SeaTalkng Terminator at each end of the backbone. Secure the Terminator
     by locking it, in the same way as for the SeaTalkng connectors.

     Fitting Blanking Plugs
     When all cables have been run and connected, fit a SeaTalkng Blanking Plug to each
     unused spur connector on SeaTalkng 5-Way Connectors and T-Pieces. Secure each
     blanking plug by locking it, in the same way as for SeaTalkng connectors.

Chapter 3: Post installation procedures
3.1 Checks
       When the backbone has been fitted and the spur cables connected, carry out the
       following checks before applying power:
          Ensure that SeaTalkng is powered from just ONE 12 V source.If SeaTalkng is
           connected to any other SeaTalk system, make sure this system does not have its
           own separate power source.
          Ensure all backbone connectors are secure.
          Ensure all products are securely connected to their respective spur cables.
          Ensure Terminators are securely fitted at each end of the backbone.

3.2 Maintenance
       Periodically check that:
        System connections are secure.
        The cables for signs of chafing and other damage. Replace as necessary.

3.3 Troubleshooting
       If SeaTalkng appears not to be operating as it should, first check for error messages on
       any of the products connected to the system. If this does not resolve the problem,
       ensure that:
        All products in the system are fully serviceable.
        All system connections are secure.
        All cables are in good condition and that there are no breaks or other damage.
        SeaTalkng is configured correctly, as described in Chapter 2. In particular, check
           that:
            There is only one backbone, terminated with just two terminators, i.e. one at
               each end of the backbone.
            Terminators are NOT fitted to any spur.
