Garmin Marine Network Considerations
A Garmin Marine Network PoE Isolation Coupler (010-10580-10) must be used when connecting any third-party
device, such as a FLIR
camera, to a Garmin Marine Network. Connecting a Power over Ethernet (PoE) device
®
directly to a Garmin Marine Network chartplotter damages the Garmin chartplotter and may damage the PoE
device. Connecting any third-party device directly to a Garmin Marine Network chartplotter will cause abnormal
behavior on the Garmin devices, including the devices not properly turning off or the software becoming
inoperable.
This device can connect to additional Garmin Marine Network devices to share data such as radar, sonar,
and detailed mapping. When connecting Garmin Marine Network devices to this device, observe these
considerations.
• All devices connected to the Garmin Marine Network must be connected to the same ground. If multiple
power sources are used for Garmin Marine Network devices, you must tie all ground connections from all
power supplies together using a low resistance connection or tie them to a common ground bus bar, if
available.
• A Garmin Marine Network cable must be used for all Garmin Marine Network connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be used for Garmin Marine Network connections.
◦ Additional Garmin Marine Network cables and connectors are available from your Garmin dealer.
• The NETWORK ports on the device each act as a network switch. Any compatible device can be connected to
any NETWORK port to share data with all devices on the boat connected by a Garmin Marine Network cable.
NMEA 2000 Considerations
If you are connecting to an existing NMEA 2000 network, identify the NMEA 2000 power cable. Only one NMEA
2000 power cable is required for the NMEA 2000 network to operate properly.
A NMEA 2000 Power Isolator (010-11580-00) should be used in installations where the existing NMEA 2000
network manufacturer is unknown.
If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through
another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to
the battery directly.
This device can connect to a NMEA 2000 network on your boat to share data from NMEA 2000 compatible
devices such as a GPS antenna or a VHF radio. The included NMEA 2000 cables and connectors allow you to
connect the device to your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network you
can create a basic one using cables from Garmin.
This device is not powered through the NMEA 2000 network. You must connect the device to a power source
(Connecting the Wiring Harness to Power,
If you are unfamiliar with NMEA 2000, you should read the Technical Reference for NMEA 2000 Products at
garmin.com/manuals/nmea_2000.
The port labeled NMEA 2000 is used to connect the device to a standard NMEA 2000 network.
