by passive mode, I THINK I know what you mean but want to confirm. I think that means leave my connection from transformer to track and separately connect the commander unit to the track. Correct?
Yes, that’s correct.
I have Lionel Power Masters connected to my loops/blocks so I can use my CAB-1 with conventional. Does this set up impede the Remote Commander?
No, it will not.
You can use the DCS Remote Commander to reset most PS3 engines but not PS2 engines.
