I have old Stowe Navigator 1, Navsounder and Windvane heads, all the sensors don't work. I don't have any databox. The wiring on my boat is a nightmare to get to and instead of replacing these old screens in the cockpit, I was wondering if I could use the existing wiring and screens fed by data from OpenPlotter over NMEA 0183. Did you get yours to work, do you think it would be possible to have them display data?
just remember that NMEA0183 is single talker, multi listener, so it you are bringing data in from multiple devices you will need 2 wires for each transmitter (talker) and then an additional 1 (if you are lucky and you can share the ground) or 2 wires for opposite direction. what I have done is bring everything into the pi (signalK) and then out via one transmitter pair (2 wires) from the pi out to everything else.
