I don't have a diagram yet, I started just with the devices what I already have it and I intend to connect other device into the future (like AIS transponder and maybe more)
For now, I need to have the following:
1. Bidirectional NMEA0183/38400bps for Garmin Echomap chartplotter which will provide GPS and active route data for Raymarine Type 150 autopilot course computer and Icom VHF with DSC (and, of course what other devices will need this data).
Same Garmin will need sentences from various sources like: Raymarine AP course computer, DSC sentences from VHF, generic navigation data like depth, water temperature, outside air temperature and so on from Raymarine sensors (from a Seatalk-to-NMEA adapter) and also, into the future, the AIS data from the AIS transponder (I think will be through NMEA2000, not yet operational)
2. Output NMEA0183/4800bps for Icom VHF. Have to provide the GPS sentences from Garmin. Filter for allow only needed sentences for Icom is required.
I'm not sure yet, but I think the VHF should be able to provide DSC related data to Garmin, so, in this case, this connection should be bidirectional, too.
3. Bidirectional NMEA0183/4800bps for Raymarine AP course computer. It should output data from Garmin chartplotter and provide data back to Garmin (for running AP in Track mode) and other additional data like heading.
As far as I understand OP/SK/kplex, proper filtering rules of sentences is mandatory. And also settings for serial connections (in/out/both, like kplex do).
Maybe there are other ways to do that but, for now, this is how I had some success, using kplex/SK under OP v1.2
I will try to take a look at node-red also, if you say will help with this.
Thank you.
