9GPSMAP 3000 Series Installation Instructions
Garmin Marine Network
The Garmin Marine Network is a waterproof ethernet-based system that allows Garmin chartplotters to communicate with Garmin sensors
and other Garmin chartplotters over the network. Waterproof RJ-45 connections allow for simple installation and high-speed connectivity. For
a simple installation with one Garmin chartplotter and one Garmin sensor, the two devices can be directly connected with a Garmin Marine
Network cable.
Power connections for network components are not shown in the following illustrations. All components of the Garmin Marine Network must
be connected to power, because they do not receive power through the network connections.

can add up to ve total devices to the Network Port Expander. If more than ve are needed, you can add more Network Port Expanders to the
network. This network is NOT compatible with PC networks. Some examples
of the Garmin Marine Network are included below. Refer to the individual installation instructions for the individual sensors. Additional
Garmin network cables are available from your Garmin dealer or direct from Garmin.
You can also include GPSMAP 4000/5000 series chartplotters in your Garmin Marine Network. Refer to the GPSMAP 4000/5000 Series
