comprises two or more backbone cables connected in series There must be only one backbone and this must be terminated with two terminators one at each end of the backbone Do NOT connect a terminator to any spurIn a SeaTalk system and any system to which it is connectedAs 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 documentsThere must be only one power sourceIt is particularly important to be aware of these requirements when connecting to another system For example in Raymarine SeaTalk1 power is often supplied from the system male adaptor cableConnects SeaTalk products to

combined systemYou connect only one source for any data type unless permission is specifically given in the relevant product documentsYou connect only one power source Limitations when SeaTalk1 products are connectedIf SeaTalk and SeaTalk1 products are used together do NOT connect an NMEA2000 backbone as this product combination could compromise the integrity of the NMEA2000 system Using with you do not want to connect to NMEA2000 you can connect a SeaTalksystem to SeaTalk1 using a suitable SeaTalk bridging product such as an ST70 instrumentnd adaptor cables to connect the two systems If you intend doing this note thatYou can connect a single SeaTalk1work to SeaTalk using an adaptor cable and one bridging product eg ST70 instrumentYou can connect two separate to SeaTalk using different adaptor cables and bridging products eg ST70 instruments but the two SeaTalk1 networks must NOT be connected of acceptable and unacceptable scenarios are shown in Figure 13 and Figure 14

for installation equipment and accessories conform to the appropriate Compatibility EMClations This minimizes interference between equipment which could otherwise affect the performance of your systemCorrect installation is required to ensure that EMC performance is not compromisedFor optimum EMC performance we recommend thatRaymarine equipment and the cables connected to it areAt least 3 ft 1 m any equipment transmitting or cables carrying radio signals eg VHF radios cables and antennas In the case of SSB radios the distance should be increased to 7 ft 2 mMore than 7 ft 2 mfrom the path of a radar beam A radar beam can normally be assumed to spread 20 degrees above and below the radiating elementThe 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 specified cables are usedCables are not cut or extended unless doing so is detailed in the installation constraints on the installation prevent any of the above always allow the maximum separation possible between different items of electrical equipmentThis will provide the best conditions for EMC performance for the 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 completeUse only ferrites of the correct type supplied by Raymarine authorized to nonRaymarine equipmentIf 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 unitTools requiredBefore installing SeaTalk ensure you have the appropriate tools In most cases a typical fitters toolkit should suffice provided it has tools to enable you toDrill holes for cable runsConnect prepared bare wire ends to terminal Page 9

product to keep spur lengths to a connect to the backbone via spur cables Spurs connect to the backbone via either a SeaTalk TPiece or a SeaTalk 5Way Connector Power supply is important that power for SeaTalk is provided from only one power source If you intend using your SeaTalk system with any other system eg SeaTalk1ower may already be connected to the other system If this is the case do NOT connect an additional power source to SeaTalkProduct loadingThe number of products you can connect to a SeaTalk 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 LENhich indicates how much power it consumesPower sourcesA SeaTalk system requires one 12 V dc supply connected to the This can be providedBy a batteryFrom a Raymarine Course Computer via SeaTalk andor SeaTalkNote 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 SeaTalkOn 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 power source must be protected by a 5 A fuse or a circuit breaker providing equivalent connection pointBalanced systemWe recommend that as a general rule power is connected to a SeaTalk system in such a way that the current drawn on each side of the power connection point is equalThis is termed a balanced systemFigure 21 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 Page 10 Tuesday May 22 2007 253 PMChapter 2 Installation11 Figure 21 Where to connect SeaTalk power in a balanced systemSmall 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 power loadingThe total load permissible in a SeaTalk system is defined in terms of the total LEN of all products connected to the system and depends on the length of the system loadingThe maximum loading total LEN for balanced SeaTalk 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 Unbalanced system loadingThe maximum LEN for unbalanced SeaTalk systems up to 197 ft 60 m is given in the following table Backbone lengthTotal LENBackbone lengthTotal LEN197 ft 60 m or

Tuesday May 22 2007 253 PM12SeaTalk Reference ManualSystem limitationsIn a SeaTalk systemThe total length of backbone cable between the two Terminators must not exceed 656 ft 200 mThe length of any individual spur must not exceed 16 ft 4 in 5 mThe 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 mor 6 spurs each of 16 ft 4 in 5 mThe total LEN in the system must not exceed the value detailed under Permitted power planning SeaTalk cable routes see Figure 22 and Figure 23nsure 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 Figure 22 Typical SeaTalk SeaTalk SeaTalk 5Way Connector5Way Page 12 Tuesday May 22 2007 253

following guidelinesDo not run cables where they are likely to be easily damagedIf a cable has to be fed through the deck always use a proprietary deck glandWhere cables are fed through holes in bulkheads etc always use the appropriate grommets to prevent chafingSecure long cable runs so they do not present a hazardDo not position cable connectors in Page 14 Tuesday May 22 2007 253 PMChapter 2 BackboneBuild 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 eitherTPiece part number A06028 Use where you want to connect a spur cable to just one product5Way Connector part number A06064 Use where you want to connect more than one spur cable to products fitted close to one another eg in the Extender part number A06030 Use as necessary to connect lengths of backbone cable Backbone ExtenderThe Backbone Extender A06030 is suitable only for connecting backbone cables Do NOT attempt to use it to join spur cables or damage could spursAt each connecting device TPiece or 5Way 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 productWhere space is limited eg behind instrument consoles it may be easier to use an elbow spur cable rather than the conventional straight spurConnecting powerThis section describes how to connect power to a standalone SeaTalk system If your SeaTalk system is connected to any other system eg another SeaTalk system and the other system already has its own power source do NOT connect another power source to SeaTalkCAUTION Do not connect power until installation is completeBefore connecting a power cable to the ensure it is not connected to a power sourceFor optimum SeaTalk 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 systemIf it is not possible to do this and the SeaTalk backbone is less than 197 ft 60 mngth you may connect the power source to form an unbalanced systemEnsure that the power source is protected by a 5 A fuse or a circuit breaker providing equivalent systemTo connect power for a balanced SeaTalk the total LEN of the products in the system 2Divide the total LEN by two and note the Page 15 Tuesday May 22 2007 253 PM16SeaTalk Reference 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 split4At this point fit a TPiece A06028 then Connect a SeaTalk Power Cable A06049 to the white connector on the TPiece See Figure 255Ensure 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 25 Connecting power to a balanced systemIf the backbone is less than 197 ft 60 m you can connect your power source to form an unbalanced system as follows1At one end of the backbone fit a TPiece A06028 then connect a SeaTalk Power Cable A06049 to the white connector on the TPiece2Ensure 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 the backbone is in position use a suitable connecting device eg a TPiece to connect a SeaTalk Terminator at each end of the backbone Secure the Terminator by locking it in the same way as for the SeaTalk Blanking PlugsWhen all cables have been run and connected fit a SeaTalk Blanking Plug to each unused spur connector on SeaTalk 5Way Connectors and TPieces Secure each blanking plug by locking it in the same way as for SeaTalk Page 16 Tuesday May 22 2007 253 PMChapter 3 Post installation 3Post installation the backbone has been fitted and the spur cables connected carry out the following checks before applying powerEnsure that SeaTalkng is powered from just ONE 12 V sourceIf SeaTalkng is connected to any other SeaTalk system make sure this system does not have its own separate power sourceEnsure all backbone connectors are secureEnsure all products are securely connected to their respective spur cablesEnsure Terminators are securely fitted at each end of the check thatSystem connections are secureThe cables for signs of chafing and other damage Replace as 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 thatAll products in the
