Default Question on Networking devices

What data will two Garmin units share between them via a NEMA set up? Only the data fed from a similar networked device? For instance, if I dont also have a Radar or Transducer that can connect to Nema, that data will only be available to the unit its plugged into correct?

To share images such as Charts,Radar and sonar you need to use an ethernet cable...or called also a network cable.

NMEA 2000 shares digital information..fuel usage, way points etc.along the network.....but no images..

Ok - makes sense. Picked up a cable today.
Will that function then as a Mirror of one to the other, or will each unit be able to then display its own data?
