Elvox tab 7549

Hi,
I’m trying to connect the Opener with the elvox tab 7549 intercom. There are only 1 2 FP and M connectors - I don’t know how to connect it, because in the manual from the pinned post it doesn’t work much for me. Has anyone tried to connect this model?

i have the elvox tab 7539 but also only with those 4 cables: 1, 2, FP, M. did you figure out how this works?

any news?
