Hi paulus.v
that's a good point checking if the signal goes through the optocoupler.
Regarding the setting - I have tried anything from A to Z with no success.
But help me - when the switch-setting is done in one or the other way - shouldn't it show at the Diagnostic-Page?
I think I saw something similar in one of the videos describing switch assembly (... that's what 99% of the video shows).
In case of connecting the wires to the controller - so far I found tons of it connecting to a parallel port. I suggested, that USB is rather new in this field?
But thanks for the hint! I will try and come back!
Cheers
