Thanks everyone.  I purchased the booster. Ill try the CV29 and let everyone know how it goes.  Are NEW QSI decoders different? How so?

 

Here is a pretty good rundown on the QSI Titan versus the original QSI Quantum.

Uh.....I think setting the long address in a decoder is governed by the NCE manual, not the QSI manual.

I just set any loco on the track and follow the instructions in the first few pages in the NCE manual.

Is OP doing something more complicated than that?

that's interesting ! 

I finally got the address changed. I changed CV29=38 then CV17 then 18 and it worked. CV29 was the key.

 I originally tried to do it the NCE way was I o with the BLI Locos but it didn't work.

What was the value of CV29 before you changed it?

honestly, Indifferent I DON'T KNOW. But I guess it must have been 6 because the 128 speed option worked.

That's another way JMRI is handy. 
 
Whenever I get a new loco, or add a decoder to a loco, the first thing I do is put it on the programming track and have JMRI read ALL the CV's. 
 
Then I save that JMRI roster entry on my computer, and have a baseline that I can always go back to if I need it.

 You should do CV29 LAST, after CV17 and CV18, otherwise yoou runt he risk of getting the loco set on a completely unknown address.

 As for what the value of CV29 was BEFORE he set it to 38 - frankly, what does it matter? It was wrong for a long address, that's for sure. My beef with sooome oof the 'simpler' systems isn't that there is no CV readback - it's that there is no dedicated program track, which means it's easy for the beginner to program every loco on the tracks. Sometimes it may be nice to knwooo what's in there befoore starting, but in a case like this where what was in there was wrong - don't think it would have helped much. I'd lay odds that it was 6, which is the default, since it wasn't being changed, plus the loco ran on address 3.

 I also suspec the automated long address programming, where it calculates CV17 and CV18 and CV29 for you, in the PowerPro has the same problem with QSI that the Zephyr does - it sends out the 3 CV values too fast for the QSI decoder too process. I had the same issue until I got a DT400 throottle, the automated address programmign on it prompts you to enable a long address, therefore there is human 'wait time' built in to the process so by the time you hit the Yes button, the QSI decoder is ready to accept the CV29 value. I had no issue programming older Broadway (when they used QSI) and Atlas locos with my Zephyr once I got the extra throttle. No booster needed. Just a 'wait state'.

Why does it matter what the value of CV29 was before he set it to 38?

It matters because that was why he could not get the loco to respond to the long address. My guess is your guess. The value was probably 6. That meant that he did not program CV29 to accept a long address. Plus, it may have been that CV1 (short address) was 'on' and that CV17 and CV18 were not properly valued.

Interesting you should say that, Randy.  I learned that tip on my own, but sort of by accident/luck/wondering-if-the-system-needed-a-pause from me.  I would hit the button to enter the add on the DT400, but learned to pause-two-three before hitting the button on the "long add y?' Once I caught on, I have never had a swing and a miss.

Dunno, Randy said "no booster needed", but the booster is needed to get the Power Pro to read the QSI decoder on the programming track. Once I installed the PTB-100, I never again had a problem trying to read a sound decoder on the programming track.

 Only thing is, you can't wait TOO long or the prompt times out and you have to start over. I usually just take advantage of the fact that it repeats the prompt until you exit programming - so if the first time I hit Y it doesn't work, it will the second or third time.

 Might need it to read, but a lot of people rush out to get program track boosters thinking they can't write to the loco. They read OK on my Zephyr. All the program track boosters in the world won't help Selector - his DB150 has no readback capability. However, that DB150 does put out a stronger program pulse than most systems with a dedicated program track, so while it can't read anything - there's nothing it can't write. The bench programming system at the club, if I don;t have my PR3 program track, is a DB150 and throttle. Most common thing is address change - we operate on a first come, first serve basis, so the guy with 2102 who was there helping set up gets to stay 2102 and the next one that shows up has to be something else.

Yeah, but we're not talking about Crandell (Selector), we are talking about Gary (the OP) who has an NCE Power Pro that cannot read a QSI Quantum decoder on the Programming Track because NCE never bothered to upgrade its command station to read sound decoders. Now that Gary has ordered a PTB-100, once it is installed, he will be able to read, and more importantly write to, the QSI Quantum decoder, and any other sound decoder, on the Programming Track.

Ok got the PTB-100 today Big Smile seems simple to hook-up. Just 1 question, do the black wires connect to the power supply that supplies the command station or do I need to purchase a separate wall wart?

If I can I would like to tap into the terminal block that feeds the Track Busses on the feed side.

Soundtraxx gives two options for wiring the PTB-100 to a power supply.

One way to do it is to connect the two black wires to the power inputs to your command station. This is the same connection as the outputs from the command station power supply.

The other way is to connect the two black wires to a separate power source such as a wall wart or power pack. I use this option.

Be sure to observe the minimum and maximum voltages stated in the PTB-100 instruction sheet.

It's costing $$ already.  Found out that the Bachman DCC Loco I have has a EZ Command Diesel Decoder with VERY few programing options. So I bought an NCE BACH-DSL replacement full function deccder to replace it.  I figure it's a good one to try replacing a decoder on since it's a pretty cheap DCC locomotive. Geeked
