OK, so in the manual it says:
Autopilot Output Port: Connect any
NMEA 0183 compatible
autopilot. Select the correct
serial port from the list.
OpenCPN does accept autopilot output on the main
GPS input port, using the same baud rate, unless it is set to "AIS Port (Shared)".
Hmm... unfortunately I have a complete 0183
network through two multiplexers and it all funnels into the computer via a USB cable from the second multiplexer. I was hoping to have just that one connection to the computer; with
wind,
water,
compass,
GPS and
AIS data coming to the computer and Autopilot data coming from the computer.
Is there a compelling reason why the code cannot have the same port specified for
AIS, GPS and Autopilot? Is it a matter of the AIS coming in at 38,400 baud and the autopilot needing the data going out to be at 4800?
