Networks Containing Only Garmin BlueNet Devices

Creating a network consisting of only Garmin BlueNet™ devices is very straightforward with few considerations.
NOTICE

Connecting a legacy Garmin® Marine Network device directly to a Garmin BlueNet chartplotter or a Garmin BlueNet 20 switch is not possible, and will result in poor network performance. If you plan to connect a legacy Garmin Marine Network device to a Garmin BlueNet network, you must install a Garmin BlueNet 30 gateway (Connecting Legacy Garmin Marine Network Devices to a Garmin BlueNet Network).

  • You should confirm that your device supports Garmin BlueNet network technology by observing the connector type (Network Port Connector Details) and consulting the compatibility reference in this document (Garmin BlueNet Device Compatibility).

  • Some devices, such as a GPSMAP® 9000 series chartplotter, have multiple NETWORK ports on the back.

    • When a device has multiple Garmin BlueNet NETWORK ports, it acts as a network switch, and you can connect additional Garmin BlueNet devices to open ports on the device.

    • For example, if you have two GPSMAP 9224 chartplotters, they each have four NETWORK ports on the back. After connecting them together using a Garmin BlueNet network cable, you can connect up to six additional Garmin BlueNet devices to the open ports on the chartplotters.

  • Some devices, such as a GMR™ xHD3 open-array radar, have a single NETWORK port.

    • When a device has a single Garmin BlueNet NETWORK port, it should connect to another device with multiple ports so the data can be shared with other Garmin BlueNet devices.

    • If needed, you can install a Garmin BlueNet 20 switch if you do not have enough open ports on other devices in the network.
