Garmin BlueNet Network Considerations
This device can connect to additional Garmin devices to share data such as radar, sonar, and detailed mapping
using Garmin BlueNet technology. For more information about Garmin BlueNet technology, including best
practices for properly constructing a network that contains both Garmin BlueNet devices and legacy Garmin
Marine Network devices, go to garmin.com/manuals/bluenet.
When connecting Garmin BlueNet devices and legacy Garmin Marine Network devices to this device, observe
these considerations.
• The NETWORK ports on the device each act as a Garmin BlueNet network switch. Any Garmin BlueNet device
can connect to any NETWORK port to share data with all devices on the boat connected by a Garmin BlueNet
cable.
• You can connect legacy Garmin Marine Network devices to this device if you install a Garmin BlueNet 30
gateway.
• All devices connected to the Garmin BlueNet network must be connected to the same ground. If multiple
power sources are used for Garmin BlueNet 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.
• You must use a Garmin BlueNet network cable for all Garmin BlueNet network connections.
◦ You must not use third-party CAT5 cable and RJ45 connectors for Garmin BlueNet network connections.
◦ Additional Garmin BlueNet cables and connectors are available from your Garmin dealer or from
.com.

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 to Power,
page 7).
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.
