[TG] [TG11] SeaTalk1 to NMEA 2000

Hello Neil,

I would think that Cat5e would work ok for cabling, but as far as the other question goes, no, AIS data cannot be sent at 4800 baud (well, to be literally accurate, you could send AIS messages but you would run out of bandwidth in high-traffic areas and for this reason AIS messages are not present in the standard 4800-baud NMEA spec and will be ignored by our MFDs at that speed.) See the 3rd of my bullet-points before:

Quote:If your C80's NMEA0183 port is already in use (usually to provide GPS data to a DSC VHF), you will need a multi-speed NMEA0183 multiplexer in order to be able to get AIS data into the C80 at the required 38,400 baud rate and still get standard 4800 NMEA0183 to the VHF (the Classic displays have only a single comms device which operates at a single speed for both input and output.) Raymarine AIS transceivers include a multiplexer to make this connection easy, but third-party may not.

Regards,
Tom
