I assume that you used a Simnet to NMEA 2000
adapter cable to connect your new Precision 9 Compass
to the Simnet network so it could provide heading information to your autopilot
If you have another of those cables
and a spare socket on your Simnet network, you can connect the Vesper XB8000 into the Simnet network, and it will convert the NMEA 2000
PGN 127250 Heading message into the NMEA
183 HDG sentence which will get the heading information into OpenCPN
in the same way you are getting GPS
position information from the XB8000 into OpenCPN
. The Vesper XB8000 performs a limited number of NMEA
2000 to NMEA 183 conversions, of which heading is one of those.
No need to splice cables
or bastardise anything.
The one thing I do not understand is the role of the AT10. I'm guessing it was previously connected to your Simnet network and was used to get heading data from the Simnet network, convert it to NMEA 183 and I'm guessing to provide heading data to OpenCPN. Not sure why you needed it when the RC42 has both Simnet and NMEA 183 connections.
Or do you have an AT10HD which is the "high speed", "reverse" version of the AT10 and is designed to get heading data from a 10Hz NMEA 183 compass
, convert and transmit it onto the Simnet network, usually for consumption
by a RI10 Radar
Interface in order for it to provide MARPA and Radar
Overlay support on Simrad
As you had mentioned a Halo radar, not sure why the RI10 is necessary as I thought they were only used with the older broadband
