You can definitely have multiple Zeus displays on the
NMEA 2000 network, where each works independently. I have a 9" Zeus 2 at my port
helm and a 7" Zeus 2 at my starboard
helm. I even will run two different sets of
charts (e.g. one running
Navionics, the other running C-Map) so I can have two different views into the area I am.
You will need to go to
Navico (B&G,
Simrad, Lowrance) radar for the Zeus plotters. I'm pretty sure that if you want radar display options on both plotters, they will all need to be on the same ethernet network. If you only want radar on one plotter, you can directly connect the Ethernet cable from the radar's RI-10 controller to the ethernet port on one of the chart plotters. There are several options (both from
Navico or other 3rd party options) if you want to network all of the devices. If you go 3rd party with traditional RJ-45 connectors, you will be looking at either splicing
cables or
purchasing the Navico ethernet to RJ-45
cables.
