Step Connection the 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 (chartplotter, radar, GMS 10), attach the RJ-45 marine network cable to an open RJ-45 socket on the GMS 10 network power expander. Tighten the RJ-45 locking ring clockwise until it is firmly sealed.

NOTE: 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.
