Suddenly the little matter of handrails and imcompatible DCC systems is not so bad...today I took my BLI T1 and ran it on our club layout. After a few minutes, it started surging, then almost stopping. Nothing seemed to help it, even resetting everything with cv8 to 8. I removed it from the track, and after I got home, I tried it on my home layout. Where the motor driver in the decoder failed completely. Everything else works, but there is zero voltage going to the motor. If I turn the motor by hand, it will make chuff sounds and smoke will puff, and all the lights work as they should. I guess it will be time for yet another phone call to BLI.
Sigh...

If it weren't for bad luck....
About the club DCC system, I hope to speak with Obi-Wan today. However, a thought occurred to me this morning in the shower. (I think well in the bathroom) Has anyone cleared the consists from the command station lately? Follow along if you will. With the larger Brand D systems, when you get done running a consist, you "dispatch off" your engines and the command station forgets all about them. Not so with NCE. You merely select another engine (if not in a consist) or consist and drive off. The consist stays active in the command station. On a home layout, where a lot of consists stay unchanged, this can be an advantage. On a club layout, a problem. If a club member is running a consist with any unit having the same address as yours, the is a conflict. If the same member removes his locos from the layout, but does not "kill" his consist, there is a conflict. Even if YOU run a consist of locos # 123,#456, #789, take them home and come back later with # 123, #741, #357 guess what? 123 is still held in another consist.
Of course, we've run into this issue before with our modular display layout, so much that is is S.O.P to clear the command station after every show. Seems no matter how much you scold, ridicule or pester some people, they just can't bring it on themselves to clean up their own messes. heck, were lucky if some throw the mainline switches back after entering or diverging from the main!
So thats my 2 cents,
Like I said, I'll talk to Obi-Wan to be sure. I
Sorry to hear about your BLI giving you problems.
Karl, I check and kill all consists when I arrive a the clubhouse, as some of our members don't clear them whe they are done.
The decoders I am having trouble with are all Digitrax decoders, and they work like they are supposed to. Until I put them in a consist, any consist, even a consist of one unit by itself.
As for the BLI issue, it is interesting the problem started on the same club layout I am having Digitrax trouble on. Coincidence?
By chance, are these Digitrax 120 series decoders??
They cant be advance consisted (NCE's preferred method) and must be "old style" or force consisted on NCE. http://www.ncedcc.com/pdf/PH5.PDF See page 45 for details.
Obi Wan is not in his cave, well try again later!
Sounds similar to the problems I had with my locos on a friends layout. He has an NCE system. Most of my decoders are Digitrax DZ125's and thinking about it it was those decoders that gave us the most problems. Running the locos together in an advanced consist was a no-go but setting them all to the same address and killing BEMF on all but the lead unit worked better than anything. I still run them that way on my own layout. It has nothing to do with the brand of locos either. Many of mine are rebuilds and some are home builds of disparate pieces from here and there.
Karl, the decoders are a variety of almost every model and type Digitrax has made over the last 15 years or so. Dh123, dn 143, 163, the Kato replacement boards, etc.
Some good news, sort of. BLI is sending me a replacement decoder for the T1, it should be here in plenty of time for our open house.
Athearn is sending me replacement handrails for the dd40, so I should hqve it fixed pretty soon as well. I did find out it will not run on part of the club layout, it gets fouled in some of the scenery (plaster mountains).

I can read back cv19, but not on my home system. The DB150 does not read back. I can read back on decoder pro, the NCE system (on the main), and my QSI quantum programmer.Terry
Can you write to CV 19, or just read it?? ,. if you can read CV19, but not write to it, then you cannot do advanced consisting
See if you can put a bogus number, like 2 then read it back after cycling power to the engine
I've had DH120s and DH121s do stupid stuff before, and Jeffrey has reported issues with 125s. make me suspect Digitrax decoders of that age.
FWIW, When you get them in a 4 pack D13SR's are pretty cheap. Or you can mail all of them off to NCE and for 10 bucks each plus 2 dollars shipping, they will replace them with comparable NCE units!
Hmmmm??I can read back cv19, but not on my home system. The DB150 does not read back. I can read back on decoder pro, the NCE system (on the main), and my QSI quantum programmer.
Nice guy! Will he give ya 9 more???The point has become moot on one of my engines, as a fellow club member gave me a Loksound Micro Select, which I installed in my C&O GP9.
Hmmmm??
:
The Digitrax Super Empire Builder doesn't support readback of cv's. I can read cv19, and of course the other cv's, on all the other systems. Even my QSI Quantum Programmer will read back.
I had one of those originally, and foolishly upgraded to a Zephyr Xtra. That is something both I and Digitrax would like to forget. The replacement for the Zephyr is the Empire Builder. Its only real drawback is a lack of ability to read back cvs, and I do have a programmer for that anyway.Glad I have a Digitrax Zephyr. Reading CV's isn't a problem on the program track.
