GMR 400/600/1200 xHD Installation Instructions
Connecting the Radar to the Garmin Marine Network
For a stand-alone network (chartplotter and radar only), attach the RJ-45 marine network cable to the RJ-45 socket on the back of the
chartplotter. For an expanded network (including a chartplotter, radar, a GMS 10, etc.), attach the RJ-45 marine network cable to an open RJ-45
socket on the GMS 10 network expander. Tighten the RJ-45 locking ring clockwise until it is firmly sealed.

Each component of the expanded network must be installed according to its installation instructions. These diagrams only show how a
GMR 404/406 radar interacts with a network and do not show proper wiring for other network components.
nOTe:
Every device connected to the Garmin Marine Network must be connected to the power supply for the boat. These diagrams show the
network connections; however, they do not show the power connections. Wire each device according to the appropriate installation instructions.
