Cerbo GX Manual

The disadvantage of cutting pin 7 is that switching the VE.Bus device off will be less effective: although it will stop charging and

inverting, it will still be in standby mode and therefore drawing more current from the battery than if pin 7 had been left in place.

Typically this is only relevant in Marine or Automotive systems where it's normal to regularly switch the VE.Bus device off. For

those types of systems we recommend that you do not cut pin 7, but simply power the Cerbo GX from the battery.

13.21. Q21: I love Linux, programming, Victron and the Cerbo GX. Can I do

more?

Yes you can! We intend to release almost all code as open source, but we are not that far yet. What we can offer today is that

many parts of the software are in script or other non-precompiled languages, such as Python and QML, and therefore available

on your Cerbo GX and easy to change. Root password and more information is available here.

13.22. Q22: How do I change the logo

Typic the following address into the web browser of a device connected to the same network. Using this address as a tem-

plate: http://[ip-here]/logo.php (inserting your device’s IP address between the square brackets). The IP address can be found by

going to Settings > Ethernet or Wifi. Once the page is loaded, Choose an image file from your device. Re-boot the GX device.

13.23. Q23: Multi restarts all the time (after every 10sec)

Please check the remote switch connection on the Multi control PCB. There should be a wire bridge between the left and middle

terminal. The Cerbo GX switches a line which enables the power of the Multi control board. After 10 seconds this line is released

and the Multi should take over from there. When the remote switch connection is not wired the Multi is unable to take over it's own

supply. The Cerbo GX will retry, the Multi will boot and after 10 seconds stop, and so on.

13.24. Q24: What is Error #42?

If the GX Device shows an Error 42 - Hardware fault. In that case, the flash storage on the device is corrupt. As a result, settings

will not be saved (rebooting resets back to default) and other problems will rise.

This error is not recoverable in the field or by repair departments. Contact your dealer for a replacement.
