network ports
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.
Contents
• GMS 10 Network Port Expander (#010-00351-00)
• 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 traffi c 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 location 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.

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 connected 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
two chartplotters and two sensors.
Use two Expanders to allow data sharing between an even larger number of chartplotters and sensors.

LED Indicator Lights
Three indicator lights appear above each network port on your Expander:
• LNK/ACT: ON means that a link has been established between the Expander and
the attached device. A FLASHING light indicates network activity.
• DUP/COL: ON means the attached device is operating at full network capacity.
OFF or a FLASHING light means the attached device is operating at half capacity.
• 100: ON means the network port is running at 100 megabits per second. OFF
means it is running at 10 megabits per second.
FCC Compliance
The GMS10 Network Port Expander complies with Part 15 of the FCC interference
limits for Class B digital devices FOR HOME OR OFFICE USE. These limits are designed to provide more reasonable protection against harmful interference in a residential installation, and are more stringent than “outdoor” requirements.
Operation of this device is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one of the following measures: Reorient or
relocate the receiving antenna; increase the separation between the equipment and the
receiver; connect the equipment into an outlet on a circuit different from that to which
the receiver is connected; consult your Garmin dealer or an experienced radio/TV technician for help.
The GMS10 Network Port Expander does not contain any user-serviceable parts.
Repairs should only be made by an authorized Garmin service center. Unauthorized
repairs or modifi cations could result in permanent damage to the equipment, and void
your warranty and your authority to operate this device under Part 15 regulations.
