How to connect phoenix multi (VE.net) to cerbo gx (VE.Bus)

[eee]

There is a RJ45 connector inside the phoenix multi. I connected it via LAN cable to the cerbo GX, to be precise to one of the VE.bus ports. But when I do that, the phoenix multi turns off. Why? I want to see my inverter in the remote console and in the VRM.

Is this a Phoenix inverter? Or an older inverter charger?

hat is the model #, and the firmware version.

Yes, inverter of course.

For the firmware version I might need to connect my mk3-usb-device and connect it to my computer. Or is it possible to see elsewhere? Can it be updated?
