I'am also struggling to connect Seatalk, NMEA and AIS
information to my computer.
The solution Dieter gives works. Connect the send and receive pins, 2=instruments to PC and 3 PC to instruments, to the NMEA in + and NMEA out +, use the 5 pin for the NMEA - on both in and out.
This will present information from the Seatalk network to the computet and computer info, for example waypointinformation, to the Seatalk network.
Be aware that if this information is allready present, for example when a external GPS
is connected, the Seatalk network will use this information first.
My problem is to get the AIS
information on my computer. I found out that this cannot be done through my S3 Autopilot
, on the S3 the NMEA in does not bridge information to the NMEA out. If I connect my AIS to the Multiplexer it uses the NMEA in position that I would like to use for information from Computer to Seatalk. The connection works, however it took me some study to find out that AIS information can only be received by a dedicated COM port set at 38400 baut.
I would like to get into contact with sailors who have the same problems.
Next post I shall present a scheme of my solution.
Must say that I think it is a shame that Raymarine is very unclear about connection methods, as if they aim to discourage do it yourself sailors.
