Hello colleagues, 
i bought a used FB4 interface. It shows a QR code when starting and nothing is possible anymore. It is also not recognized in the Beyond. I installed a new SD card because the other one appears to be defective and can no longer be contacted. As a test, I copied the contents of one of my other FB4s onto it. Same result. Maybe one of you can tell me what's going on with this part.
Thanks in advance, Micha
