Frustrated with Raymarine SeaTalk. I put an e7D into my system (ST60 (Depth, Wind, Speed) and ST6002). The existing system was hooked together with SeaTalk. When I got the e7D I also got the SeaTalkng converter to connect the new to old SeaTalk. The result was that the pilot and GPS talked to eachother fine, the rest of the instruments are blind to the GPS. Muddling through the Raymarine forum it seems that I have maxed out the SeaTalk bus connections. What I can not figure out is how to create another bus? Any ideas?
SeaTalk instruments, autopilot components, GPS sensors, and chartplotters featuring a 1st generation SeaTalk interface which do not additionally feature a SeaTalkng interface (ex. ST40/60 Instrument Displays, ST6001, S2G, Wireless AP Controller, Raystar 125 GPS Sensor, etc.) should be interfaced to one another, in any order, using standard SeaTalk cable. SeaTalk cables can be joined using D244 SeaTalk Junction Blocks, splices, marine grade terminal strips, or R55006 SeaTalk Auxiliary Junction Boxes. SeaTalk cable is available in 15", 1m, 3m, 5m, and 9m lengths (D230, D284, D285, D286, and D287 respectively). This method of interfacing is referred to as a SeaTalk bus. Each SeaTalk to SeaTalkng Converter will support a SeaTalk bus of up to five SeaTalk devices. Should your present SeaTalk bus consist of more than five SeaTalk devices, then it will need to be divided into smaller busses including no more than five SeaTalk devices. Each bus will in turn be connected to the yellow SeaTalk port of a SeaTalk to SeaTalkng Converter. The SeaTalk to SeaTalkng Converters may be interfaced to one another via appropriate length of SeaTalkng Backbone Cable. The SeaTalk bus will need to be branched or extended and connected to the yellow (SeaTalk) port of a E22158 SeaTalk to SeaTalkng Converter Kit which has been upgraded with v1.21 or later SeaTalk to SeaTalkng Converter software. The Data Master a/c/e/eS/gS-Series MFD will in turn be interfaced to one of the white SeaTalkng spur ports of the SeaTalk to SeaTalkng Converter using an appropriate length of SeaTalkng Spur Cable ((400mm (A06038), 1m (A06039), 3m (A06040), 5m (A06041)). The SeaTalk bus will be to be disconnected from its present power source ... this may well be the red terminal of an autopilot course computer's SeaTalk port. The SeaTalk bus will instead be powered via the SeaTalk to SeaTalkng Converter. The SeaTalkng power cable supplied with the SeaTalk to SeaTalkng Converter Kit will be connected to a 12VDC power circuit and will be interfaced to the other white SeaTalkng spur ports of a SeaTalk to SeaTalkng Converter at the approximate midpoint of the LEN load of the SeaTalkng/NMEA 2000 backbone which is being created. Finally, the supplied SeaTalkng Termination Plugs will need to be installed in the two blue SeaTalkng backbone ports of the SeaTalk to SeaTalkng Converter(s). Please verify that the equipment is interfaced in the manner which has been specified.
With respect to the latter two issues, the wind instrument requires speed through water data to calculate true wind. Should one of more of the instruments have suffered a SeaTalk failure, then they will continue to work independently, but will not share data. Should the equipment have been interfaced in the manner which has been specified, then it would be recommended that the instruments be tested by Raymarine's Product Repair Center.
