GMR 20/40 Radar Installation Instructions
Final Wiring Connections
Once the scanner is installed and the cable routed, you are ready to connect the Power, Ground and Marine Network.
1. Connect the Black Ground (-) wire to the vessel’s negative power terminal.
2. Connect the Power (+) wire (with fuse holder) to the vessel’s positive power terminal.
3. For a stand-alone network (MFD and Radar only), attach the RJ-45 Marine Network Cable to the RJ-45 socket on the back of the MFD.
For an expanded network (MFD, 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.
