2 Install the locking rings on the marine network and power cables. 3 Connect the bare-wire end of the power cable to a 12 Vdc power source and to ground. 4 Align the notch on the end of the power cable with the power port on the device, and press the cable into place. 5 Tighten the locking ring. 6 Select an option: • If your boat is equipped with a GMS™ 10 network port expander, connect the network cable to an available port on the GMS 10. • If your boat is not equipped with a GMS 10 network port expander, connect the network cable directly to the network port on your chartplotter. Cable Routing Grommets When routing cables through your boat, it may be necessary to drill holes to route the cables. Cable routing grommets can be used to cover cable installation holes. The grommets do not create a waterproof seal. If necessary, apply a marine sealant after installation to weatherproof around the grommet and the cable. You can purchase grommets from your Garmin dealer or directly from Garmin at www.garmin.com.
