I have a tech question, please -- On my DCC layout, I'm replacing another vendor's auto-reversers (they weren't reliable) with OG-AR units on a couple of reversing loops. No problem, except that I want to incorporate my existing (Chubb) C/MRI DCCOD occupancy detectors in the arrangement. These are an induction-coil type of circuit board, so that track power has no direct connection in the detection circuitry.

Do I wire the AR's between the DCC buss and the occupancy detectors, or between the occupancy detectors and the rails? Thanks in advance for your help.  Rob

Rob:
You should wire the DCC bus to the OG-AR  and then the OG-AR to the detector then the detector to the track. If the detector has no connection to the track, the OG-AR switching the polarity should have no effect on the detector.
