The TwoCan plugin can connect OpenCPN to NMEA 2000
networks. It converts most NMEA
messages to their respective NMEA
183 sentences and forwards them to OpenCPN.
At the stroke of a pen the TwoCan plugin could convert NMEA 2000 engine
data however other than the NMEA 183 RPM
and XDR sentences there are no direct 1:1 conversions.
More importantly however, until the dashboard plugin supports additional gauges (RPM, Oil
temperature, etc.) there is no way to visualise such data in OpenCPN.
As others have suggested, SignalK or Openplotter may be more appropriate solutions.
