Golmar t-5822vd (bus) opener issue


I need some help with connecting the opener with the Golmar T-5822vd. It only has two wires in the Bus insert. See photo. Does anyone know how to connect this?

Many thanks!

I tried to use the genereic (bus) setup. But in the last step it asks to ring the bell and to confirm that it has rung, but then I get a screen that I have to use an alternative setup. But then I come in an infinite loop where I need to do the same setup all over again.

Did you ever get it figured out?? If so, please post pics!!
