Garmin GMS 10 Network Port Expander Owner's Manual

The GMS 10 Network Port Expander lets you connect more than two chartplotters

and other Garmin marine network devices to share data. Simply connect one end of the

network cable to your Garmin marine network device and connect the other end of the

network cable to the Expander. Then, your Garmin marine network devices will be able

to share information such as weather, mapping, and sounder data as well as position

information.

•

Garmin marine network cable (#320-00227-00)

•

7-pin power cable (#320-00023-05)

• Grommet (#252-00129-00) Use the grommet to cover holes you drill for cables.

•

Optional mounting hardware kit (#K00-00123-00)

Use the kit only if you cannot mount the Expander by using the factory-drilled

holes. The kit contains two brackets with two screws/nuts per bracket. Use the

screws and nuts to attach the bracket to the unit. Screws to secure the Expander to

your boat are not included.

Selecting a proper mount location

Mount your Expander in a location that is away from heavy foot traffic and where the

network cables can easily reach your Garmin marine network devices and the Expander.

If you foresee purchasing an additional Expander as you add Garmin network devices,

make certain you have enough space to mount two Expanders near each other. Before you

mount the Expander, consider the length at which the network cables will extend when

plugged in to the Expander and allow for this extra space. If you select a mounting loca-

tion that prevents you from using the Expander’s factory-drilled holes, use the brackets

included in the optional mounting kit. (Instructions are included in the mounting kit.)

Connecting the cable to the network port

1.

Unscrew the weather cap from a network port by turning the cap counterclockwise.

2. Connect the network cable to the network port 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.

3.

Tighten the cable cap to prevent the cable from vibrating loose.
