question

the ve.can bus should be independently powered and also should have its own start and end terminating resistors, ie it has to be setup as its own ve.can bus and the nmea converter then connects to that bus then to your n2k bus

What type of Raymarine plotter do you have ? If you can run glassbridge an ip connection between the cerbo and plotter may be better. For what it’s worth I decided to keep my ve.bus and seatalk bus seperate - too many mission critical devices on each network and troubleshooting problems is difficult enough without further complicating things. Hopefully the Ekrano does a better job of this with dual Buses. I also explored the SignalK Server and WilhelmSK which was pretty good. That said the latest beta integration with Axiom excellent.
