Garmin Marine Network Considerations - Garmin GPSMAP 7X3 Installation Instructions Manual

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.
