How to build a basic NMEA 2000 Backbone - start your own NMEA 2000 onboard network. A Force 4 Guide.

So you need to connect each device to power and the nmea to power ? The nmea won’t power the devices correct ? Thanks

Hi Jared, thank you for your question. The NMEA 2000 network is a low current network and will not power anything that draws over 1A. So chartplotters, AIS transponders, VHF radios etc need their own connection to the 12v supply. Items such as sensors and instruments can be powered from the NMEA 2000 network.
