Garmin BlueNet Connection
You can use the Garmin BlueNet™ port to connect the Garmin Signal™ VHF radio to your marine network and enable networked features.
-
When you connect a Garmin Signal VHF 400/220 head unit and up to five Garmin Signal RM 100 remote stations to the same marine network, you can fully control the radio from the head unit or any of the connected remote stations.
-
If your Garmin Signal VHF system includes only the head unit and one remote station, you can connect the devices directly to each other using a Garmin BlueNet cable.
-
If your marine network is equipped with a compatible Garmin® chartplotter, the software on your Garmin Signal VHF radio and remote stations is updated automatically when you update the software on the chartplotter (Software Updates).
For more information on Garmin BlueNet technology, you can go to garmin.com/manuals/BlueNet.
Networking Considerations
This device uses Garmin BlueNet networking technology, and is compatible with both Garmin BlueNet devices and Garmin Marine Network devices.
Before connecting this device to your network, observe these considerations.
-
If your boat is equipped with a Garmin BlueNet chartplotter, you should connect the Garmin Signal VHF radio head unit and remote stations to any open network ports on the Garmin BlueNet chartplotter or the Garmin BlueNet 20 switch, using Garmin BlueNet cables.
-
If your boat is equipped with a Garmin BlueNet chartplotter and uses a Garmin BlueNet 30 gateway to connect Garmin Marine Network devices, you should connect the Garmin Signal VHF radio head unit and remote stations to the Garmin BlueNet side of your network, if possible, for the best performance and to best support future updates.
-
If your boat is equipped with only Garmin Marine Network devices, you must use a Garmin Marine Network adapter cable to connect the Garmin Signal VHF radio head unit and each remote station to your network. You can purchase a Garmin Marine Network adapter cable from your local Garmin dealer (part number 010-12531-01) or you can go to garmin.com/accessories/GMNAdapterCable.
A Garmin Signal VHF radio remote station connected to the Garmin Marine Network side of a hybrid network cannot communicate with a Garmin Signal VHF radio head unit connected to the Garmin BlueNet side of the network. You must connect all Garmin Signal VHF radio devices to the same side of the network.
