Is there a anyone out there who could help me understand how I should connect the Opener to my Aiphone GT-1M3-L?
I have figured out that it is a BUS intercom. The Nuki generic installation guide however refers to two ports, BUS- & BUS+, which doesn’t exist on my intercom (See image below). It has B1,B2 (Video) & R1,R2 (Audio). I’m trying to figure out which ports on mine that corresponds to BUS- & BUS+ and I would very much appreciate any help.
