Garmin BlueNet 30
gateway
All Garmin BlueNet network devices must be connected on one "side" of the
gateway, and all legacy Garmin Marine Network devices must be connected
to the other "side."
NOTICE
Only one Garmin BlueNet 30 gateway can be installed in a mixed network.
Attempting to install more than one gateway in a network will result in poor
performance or no communication between devices.
Garmin BlueNet radar
Ignition or power switch
(not included)
You should connect the Garmin BlueNet 30 gateway to power through the
ignition or another physical switch. The device continues to draw power
when the system is off and drains the battery if it is connected directly.
Legacy Garmin Marine
Network cable
Garmin Marine Network cables have larger connectors that look more like a
common RJ45 network connector.
Garmin BlueNet network
cable
Garmin BlueNet network cables have smaller connectors that look more like
NMEA 2000
®
connectors.
NOTE: Garmin BlueNet network cables are not the same as NMEA 2000
cables, and you cannot use them interchangeably.
12 Vdc power source
The Garmin BlueNet 30 gateway must connect to power using the included
power cable.
Garmin BlueNet 20 switch
or Garmin BlueNet chart
plotter
If you are using a Garmin BlueNet 20 switch, the best practice is to connect
that switch to the gateway. If you are not using a switch, you can connect a
chartplotter with multiple Garmin BlueNet network ports or a single Garmin
BlueNet chartplotter to the gateway, depending on the types of devices on
your vessel.
Garmin BlueNet chart
plotter or other device
NOTE: You must have at least one Garmin BlueNet chartplotter on the boat.
The Garmin BlueNet 30 gateway is not necessary without a Garmin BlueNet
chartplotter.
GMS 10 switch or legacy
Garmin Marine Network
chartplotter
If you are using a GMS 10 switch, it is the best practice to connect that
switch to the gateway. If you are not using a switch, you can connect a
chartplotter with multiple legacy Garmin Marine Network ports or up to two
single legacy Garmin Marine Network devices to the gateway, depending on
the types of devices on your vessel.
