Jeff But it's a dry heat!
Do you have a picture of how this is wired ? Is the DB150 powering a portion of the layout outside of the reversing loop and the DCS100 is powering the PSX-AR and the reversing section or something similar ? Does it matter which way you enter the reversing section ? Have you verified that the rail sync leads on your Loconet bus are not flipped or not connected somwehere between the DCS100 and the DB150 (been there, did that, caused this type of problem). Depending upon how your Loconet is wired, remember that the front connectors on a UP panel don't have rail sync leads. Lastly, what is the trip current setting on your PSX-AR ? If it is too high then the booster will kick out before the PSX-AR.

How recently did you get the PSX-AR? Tony's/DCC Specialties reports problems with one recent batch of PSXes (they aren't clear whether it's specific to just PSX-1s through PSX-4s or to PSX-ARs), where some of them won't trip before a Digitrax command station or booster does.
Details can be found at http://www.tonystrains.com/tonystips/2008/050108.htm. You might want to contact them to help determine whether this is the cause of what you're seeing.

I just sent an e-mail to Tony's describing my problem. Tonite, I ran trains over the booster half of my layout with the booster set at HO, without any problem. I have a wye on the DCS-100 half with an MRC AR with no problem, (command station set on HO). What I just can't understand is why that side works perfectly on the N setting, but not on the HO setting. It seems to me that neither would work if there's a wiring problem. I'll see what the response is from Tony's. Note: The trip current on the PSX-AR is:3.81 Amps.
Here's a quick suggestion to rule out issues between the boosters. Take the wires off the output of the DB150 and temporarily run them over and connect them in parallel to the DCS100 outputs. Thus the entire layout will be powered off of one booster. If everything works then you know the issue is between the boosters. At that point I'd look for a Loconet wiring issue with the rail sync pins or a polarity reversal on the booster outputs to the rails.
I looked through the Digitrax manuals and can't find anything on this term either.
Too many cooks in kitchen. Take one booster off the layout. One should be the Command Station only. Any additional boosters need to be "Wired" just so to deny it command authority and turn it into a simple juice box slaved to the master command station.
In fact why are we using two sources of electricity and command information? One should be plenty in a layout.
Cut down the wiring until just the minimum necessary to run the layout and ONE reverser or toggle switch for the return loop.
Check your entire power bus to all of your track make sure that one rail is one wire and the other rail is the other wire all the way through the entire layout.
That reversing loop is a fly in the soup. Something needs to be done about it.

Hi Last Chance: Thanks for your reply. To answer your questions: My layout measures approx. 15x36 ft., not counting staging at each end. Right now, I have 8 locos on the layout, all with sound. I believe it's good practice to divide the layout into separate power sections, so a short in one section doesn't shut down the whole layout. I'd like to divide it up into even more separate sections. Anyway, the wiring for the half with the DCS-100 is at the minimum to run the layout. As i said before, It runs fine when the scale switch is set to N, but not when it's set to HO. The booster half has no problem at all. I have sent an e-mail to Digitrax describing my problem and relaying Tony's answer to see if they have a clue to what he means. I, too believe it has something to do with Tony's ARs. I'm awaiting Dave at Digitrax's reply. Note: The tip about the reversed terminals (A&B) on the DB-150 is on Digitrax's web site.

Maybe if he read his PSX-AR manuel he would find his answer. I found the answer on the web in 30 seconds.

Grampy,
Do you have a ground (actually a "common") connection between the DCS100 and the DB150?
It should be about the same gauge as your main buss, roughly #12 or #14.
(This is separate from the ground or common in the LocoNet cable)

Thank you so much for pointing that out. I'll try that jumper tonite. Well, I installed the jumper, a loco will enter the loop with the same polarity as the main, but coming out of the loop, command station trips, just like before. Back to the drawing board.
How is the Loconet connection between the DCS100 and the DB150 ? Are there intermediate connection points ? You didn't say whether you tried my suggestion of raking the outputs off the DB150 and connecting them to the DCS100 and run the entire layout of of one booster to see if that fixes things ? It will tell us more about where the problem is or isn't. If you have intermediate Loconect connections I'd try a cable from the front of the DB150 to the frint of the DCS100 and see what happens.
