Hi there!

I am trying to adapt Nuki Opener to a 2 Wire configuration with digital connection. Looking at the documentation I believe I need to use :

The board of my video door looks something like this:

Can anyone advise on how to connect each of the cables?

Thank you very much

I kinda just hacked mine,

I connected the positive and negative as normal. Door release to the door pin and the sounder cable to the led leg on my intercom, to the buzzer also works.

If you want to work out what pin does what you can use a paper clip and short the positive to the other pin and see what happens

Thank you very much

To be sure: should I follow the Generic BUS instructions?

I am not sure what do you mean with. “Door release to the door pin and the sounder cable to the led leg on my intercom”

Thank for your help!!!

Found this on the internet but not sure how applies
