I think the best way would be to connect into the Seatalk NG network and connect that to a CAN device connected to the PI or Pi's network see: https://openplotter.readthedocs.io/en/2....n_app.html
another way would be to listen to the NMEA 0183 traffic, but you are only interested in the 38400 baud rate connection, which is port 2 according to your manual. With NMEA0183 you can have multiple listeners but only one talker - so you could either listen to what is coming out of the chart plotter (Orange/Yellow, Orange/Brown). or what is going to the chart plotter from another device on Orange/white and Orange/green: see page 32 of https://www.vela-navega.com/forum/myfile...lation.pdf. to make this connection you need a RS422 to USB device - see https://openplotter.readthedocs.io/en/2....mples.html
