Connecting the cable to a Garmin marine network device
1. Connect the network cable to the network port that is located on your marine network device
(the port is labeled “Network”) by aligning the cable head with the opening of the network
port. Use the black arrow on top of the cable head as an alignment guide.
2. Tighten the cable cap to prevent the cable from vibrating loose.
Connecting the 7-pin power cable to your boat’s battery or fuse block
The GMS 10 Network Port Expander is designed to pass control signals to turn sensors
(such as the Garmin marine weather/audio satellite receiver) on and off. Thus, when you
power on/off a chartplotter that is connected to an Expander, all sensors that are also con-
nected to the Expander will automatically power on/off as well. This eliminates the need
for you to individually power on/off the sensors through a circuit breaker.
The 7-pin power cable includes a Red and Black wire. Connect the Red wire to the
positive (+) terminal on your battery or fuse block and the Black wire to the negative (-)
terminal. Do not remove the AGC/3AG 2.0 amp fuse located on the Red wire.
Maximizing data sharing among Garmin marine network devices
Use the Expander when you need to connect more than two Garmin marine network
devices. For example, if you have two chartplotters and a sensor (such as the Garmin
marine weather/audio satellite receiver), you can view the sensor’s information on both
chartplotter screens. If you run out of connection space on one Expander, you can add
another Expander to meet your data sharing needs.
Use two Expanders to allow data sharing between an even larger number of chartplotters and sensors.
