This document explains how to connect to Garmin MFDs using an Ethernet connection. The integration technology used is called Garmin OneHelm.
Make sure to also study the Marine MFD Integration by App chapter in the manual.
Note that there is an alternative method to connect, which is NMEA2000. See the NMEA2000 chapter in the main manual.
OneHelm is currently available for the following models:
Also, Active Captain is supported. Below screenshot shows ActiveCaptain, with the Victron App.
From Victron side, all GX devices (Cerbo GX, CCGX, Venus GX, and so forth) can be used and are compatible. For details on detailed product compatibility with regarding to inverter/chargers and other components, see the main Marine MFD App chapter in the GX Manual.
The Garmin needs to be connected to the GX device using Ethernet. Its not possible to connect over WiFi. For the ethernet connection, a Garmin adapter is required:
No special networking settings are necessary. Not on the Garmin; and not on the Victron GX Device.
The Garmin MFDs run a DHCP server; and the GX device are by default configured to use DHCP. After plugging in the cable, the Victron icon will show up after 10 to 30 seconds.
Connecting a Garmin MFD to a network router over Ethernet leads to IP address conflicts, due to the integrated DHCP server.
It is not possible to use a GX GSM, due to the integrated DHCP server of the Garmin MFD.
The MFD can also be connected to the Victron system using NMEA 2000, see the NMEA 2000 & MFD integration guide.
The MFD can be configured easily to display the data from the GX device. There is no need to change any instance.
To setup NMEA 2000 on the MFD, go to Settings > Communications > NMEA 2000 Setup > Device List. Here you can view information about the connected products and change their names. Note that the names are stored on the MFD and not on the NMEA 2000 device.
The following Victron related PGNs are supported:
The supported PGNs may vary per model. Please consult the manual of the MFD for a list of supported PGNs.
