2.7. Connecting a USB GPS

Use a GPS to track remote vehicles or boats and, optionally, get an alarm when they leave a designated area (geofencing). It is

also possible to download a gps-tracks.kml file which can be opened with Navlink and Google Earth for example.

Victron does not sell USB-GPS, but the Cerbo GX will support third-party GPS modules which use the NMEA0183 command-set -

almost all do. It can communicate at both 4800 and 38400 baud rates. Plug the unit into either of the two USB sockets …connec-

tion may take a few minutes, but the Cerbo GX will automatically recognize the GPS. The unit's location will automatically be sent

to the VRM online portal and its position shown on the map.

The Cerbo GX has been tested for compatibility with:

• Globalsat BU353-W SiRF STAR III 4800 baud

• Globalsat ND100 SiRF STAR III 38400 baud

• Globalsat BU353S4 SiRF STAR IV 4800 baud

• Globalsat MR350 + BR305US SiRF STAR III 4800 baud

2.8. Connecting a Fischer Panda Generator

See GX - Fischer Panda generators.

2.9. Connecting NMEA-2000 tank senders

A thrid party NMEA2000 tank sender must meet the following requirements to be visible on the GX Device:

• Transmit the NMEA2000 Fluid Level PGN, 127505

• The NMEA2000 device class needs to either General (80) in combination with function code Transducer (190), or Sensor (170).

Or, the NMEA2000 device class needs to be Sensors (75), in combination with function Fluid Level (150).

A single function reporting multiple Fluid Levels is currently not supported.

For some tank senders it is also possible to configure the capacity and the fluid type on the GX Device - for example the Maretron

TLA100. This facility may be available with other senders made by other manufacturers - it's well-worth trying.

To connect an NMEA2000 network to the VE.Can port on the Cerbo GX, use a VE.Can to NMEA2000 cable.

Alternatively, instead of a VE.Can to NMEA200, you can use a 3802 cable from Oceanic Systems: https://osukl.com/ve-can-adap-

tor/. The difference is that it lends itself well to connecting a single NMEA-2000 device into a VE.Can network. It's also able to

power a lower voltage NMEA-2000 network directly from a 48V Victron system.

Tested NMEA2000 tank senders:

• Maretron TLA100

• Navico Fluid Level Sensor Fuel-0 PK, partno. 000-11518-001. Note that this sender requires a 12V powered NMEA2000 net-

work; it breaks when connected to a 24V-powered NMEA2000 network. And note that you need a Navico display to configure

the Capacity, Fluid type, and other parameters of the sensor.

Most likely others work as well. If you know of one working well, please edit this page -or- get in touch with us on Community ->

Modifications.

2.10. Connecting IMT Solar Irradiance, Temperature and wind sensors

Compatibility and wiring

The compatible types are the Si-RS485TC Series. The optional wind and temperature sensor are also supported.

The sensor is connected using RS485 wiring, and requires our USB to RS485 accessory cable.

Follow this diagram for the connection of the Sensor to the GX device's USB port, via the RS-485 to USB interface.
