Nope. They are idle/disconnected. The circuit is pretty straightforward: directly from the booster to the PM42 to the BD1s to the blocks in the reverse loop.
Are you using the other two sections of the PM42 as circuit breakers feeding the two sections that run your reverse loops? That's generally frowned upon by Digitrax, probably because too many people had issues with it - their older manuals showed this as a valid config, it has been removed fromt eh newer ones.

Exactly! Thanks for the assurance. I simply can not get long term reliability from the PM42 (i.e. - it works okay for several hours and then will fail for no reason - same trains, same locos entering and leaving the loop at the same time, etc.) and the PSX device seem to get rave reviews here and on other forums as well. I'm doing an NMRA clinic and tour in a couple of months and don't particularly want the embarresment of a failure. Thanks.
I assume the BD1's are between the PM42 and the track? If so, it's a direct repalcement.
Presently, I have a Digitrax PM42 configured as an autoreverser feeding a reverse loop with 2 blocks via two Digitrax BD1s for occupancy detection. I want to replace the PM42 with a DCC Specialties PSX-AR. Can I do this with the same occupancy detection configuration? I can't find any information about the PSX unit other than it being shown wired directly to a reverse loop without any intervening devices. Thanks.
