Sure thing! If your NMEA 2000 GPS matches the required specs (like Garmin GPS 19X NMEA 2000), you’re good to go.
You’ll need to connect it to the Cerbo GX’s VE.Can port.
There are a couple of ways to do this: either use the VE.Can to NMEA 2000 cable or the 3802 VE.Can Adapter.
After setting it up, you can monitor your vehicle or boat from the VRM portal.

When connecting an NMEA 2000 GPS to the Cerbo GX, it’s crucial to ensure that the GPS unit adheres to the NMEA 2000 network protocol specifics, which is a standard for data communication between marine electronic devices. The NMEA 2000 device you’re using should be classified under device class 60, which refers to Navigation devices, and should specifically function as 145, which is designated for Ownship Position (GNSS) data.
Understanding NMEA 2000 Standards and Requirements
The data transmitted by your NMEA 2000 GPS must include position data (latitude and longitude), which is usually transmitted in PGN 129025. If your unit provides height information, it should be transmitted in PGN 129029. Additionally, if it tracks course and speed, those should be transmitted in PGN 129026. These PGNs (Parameter Group Numbers) are standard codes used to identify the type of data being transmitted in an NMEA 2000 network.
Compatibility of the NMEA 2000 GPS with the Cerbo GX has been specifically tested with certain models like the Garmin GPS 19X NMEA 2000. However, most NMEA 2000 compliant GPS-es should theoretically work.
Physical Connection Options: Cables and Adapters
To physically connect the NMEA 2000 GPS to your Cerbo GX, you have a couple of options. The VE.Can to NMEA 2000 cable is one such solution, which allows you to connect your NMEA 2000 network directly to the VE.Can port on the GX device. This cable comes with a fuse that, depending on whether it’s inserted or not, allows you to power the NMEA 2000 network with Victron equipment or not. Another option is the 3802 VE.Can Adapter by OSUKL, which is particularly useful for integrating a single NMEA 2000 device into a VE.Can network. This adapter is also capable of powering a lower voltage NMEA 2000 network directly from a 48V Victron system.
Voltage Considerations for 24V and 48V Systems
However, a critical consideration when connecting to 24V and 48V systems is that while all Victron components can accept up to 70V input on their CAN-bus connections, some NMEA 2000 equipment might not tolerate such high voltages. They usually require a 12V powered connection and might only work up to 30 or 36V. Therefore, it’s crucial to check the datasheet of your NMEA 2000 equipment. If your system contains NMEA 2000 components that require a network voltage below your battery voltage, consider using the 3802 VE.Can Adapter or install the VE.Can to NMEA 2000 cable without its fuse and provide the appropriate power to the NMEA 2000 network using a suitable adapter.
Remote Monitoring and Advanced Features via VRM Portal
Once your GPS is connected and configured, it will start transmitting data to the Cerbo GX, which you can monitor remotely via the VRM portal. This setup not only allows you to track your vehicle or boat’s position but also enables you to set up advanced features like geofencing, which sends an alarm when the system leaves a designated area.
Summary of Connecting NMEA 2000 GPS to Cerbo GX
In summary, connecting an NMEA 2000 GPS to Cerbo GX involves understanding and matching the technical requirements of the NMEA 2000 network and the GPS device, physically connecting the two using the appropriate adapter or cable, and ensuring the system’s voltage compatibility. Once set up, it offers robust tracking and monitoring capabilities through the VRM portal.
