A ST/NMEA board would be highly sought after, hard to find anything not too expensive.
I don't have a wind indicator at all actually
I won't get any relevant data from the sensors using Nmea, manual says that autopilot will only output these sentences on Nmea interface:
Cross Track Error XTE
Bearing to Waypoint BWC
Distance to Waypoint BWC
Waypoint Number BWC
Latitude and Longitude GLL
Magnetic Heading HDG, HDM, HDT
True Heading HDT
Locked Autopilot Heading HSC
Course Over Ground VTG
Speed Over Ground VTG
Fix/No Fix GLL
So needs either ST/STng converter, or ST/NMEA, to get instrument data into OpenCPN.
Regarding conversion to 12v, the MAX485 circuit converts rs422 to rs485 and also up to 12v. Easy peasy.
