Mark.
I guess that the subject of the thread so interested me that I did not notice the older start date.
Oh well, at least I wasn't the one who revived the thread.

According to NMRA standard 00 is broadcast to all trains...
So if a decoder sees this it responds as if it was directly addressed. (Short or long) This is great when you muck up CV1, CV17, CV18, CV19, or CV29 and don't want to transfer it back to a program track. The only disadvantage is all your other trains have to be OFF the track.

Did you get a solution to not being able to change the address after using 00 to get it back to 03? I'm having this problem with my 4-4-0 w/ Tsunami. i didn't see a response to your paragraph with that issue.
Did I overlook something?
Good morning,
I am still here. Thank God for email notification! What fixed the problem for me was using Selectors advice of using 00 to reset and then cycling the power. Regarding he issue I had with the 4-4-0, I did the 00 trick, but then for some reason I had to use a different DCC cab to change the address. I believe after all of the issues I had that the programming track connector on my cab does not work.
Below are what worked for me.
I would have have direct quotes the following but on my mobile device it will not let me.
"Dial in address "00" on your active throttle.
Enter 'programming on the main' mode, or what is called Ops Mode programming on that throttle.
Edit CV8 to have a value of '8', and hit enter...or complete the reset by entering that value.
SHUT OFF TRACK POWER!
Re-power the tracks, and acquire address '03'. Try blowing the horn.
Your loco will work on that address if you have not inadvertently locked the decoder. Most of these steps have been suggested, just not the adress '00'. I have placed them in a convenient list for you.

Are you trying to set a 2 digit or 4 digit addres for your loco? If it is a 4 digit address the Zephyr has trouble reliably setting CV 29 to recognize the address and you won't get a responsonse on that address but will on address 3. I have found that the best way to handle this is to set CV 17 , 18 and then 29 while in the programming on the main mode. You can get the values from this handy CV calculator from Digitrax: http://www.digitrax.com/support/cv/calculators/ . THis calculator is also available as the Digitrax Toolbox app for your cellphone. Hope this helps.

My apologies, I should have read more thorough.
With that problem, I had to use a different DCC cab. For some reason, the decoder would not take any response in OPS mod, and my programming track wouldn't work to program even with the PTB.
This is why I had to use a differnet cab all together. Perhaps, if you can, try and use a different cab in programming mode to see if it will change. Eventualy, I am going ot invest in the equipment to edit my CVs on the computer.
Hope this little bit will help some. I had this problem with several Locos and the 00 reset did the trick. However, I had two instances where I couldn't change the address after reset (one with a Spectrum 44-ton switcher, without sound and the 4-4-0 with sound in reference), and in both instances I had to use a different cab to change the address. It is worth metioning that I have only had serious decoder issues with Bachman locos, despite the decoder being Tsunami.
Please let me know if you get a fix or have any other questions, I would love to get to the bottoms of the issue!

I've been in touch with Soundtraxx about the problem: "You will need to change to a long address and then back to a short (e.g. change to address 1000, then change to 44). You cannot change from a short address to a short address when programming on the main, this is a safety feature. You should be able to change from 3 to 44 on the program track, but that would require a PTB-100. Please feel free to contact us at the number below for further assistance, we are happy to help."
I still can't change the address from 03 to anything else (2- or 4-digit) -- whether on the main with OPS or on the programming track with DIR. Interesting thing: when I first got this loco I WAS easily able to change the address from 03 to 44 on the main, using my Digitrax Zephyr Xtra (DCS51).
I've also tried changing CV29's values per the posts I've found in this thread.
As my bro-in-law says, "Patience, Grasshopper." Good advice, as is my calling Soundtraxx next week.
Final thought: I hope you're not in part of SC being pounded by Hurricane Matthew.

The main issue is that when you program a 4 digit address, the Zephyr calculates CV29 for you, but it then sends it out too fast for many decoders to respond. I never had a problem after I added a DT400 throttle to my system and used that to program - the DT400 prompts you to confirm setting a 2 or 4 digit address and doesn;t send CV29 until you answer Yes to the prompt.
You generally cannot change from one short address to another, or one long address to another, using Ops Mode. So if the decoder has reset and is controllable as address 3, the way around the whole CV29 thing is to use one of the many calculators available online or in the Digitrax Toolbox app they have for iOS and Android, and calculate some values for CV17, 18, and 29. Using Ops Mode with 3 selected, set CV17, then 18, and finally 29 to the values calculated. You should now lose control of the loco - select the long address you just programmed in and it should work. Now program the desired short address into CV1, and use the calculator to determine the proper value for CV29 and program that. Again, you should lose control of the loco. Select the new short address and you should be good to go.
Once upon a time this was how it always was, systems didn't calculate CV17, 18, and 29 for you. And even further back, there WERE no long addresses so there was little need to ever change CV29, just plug the address you wanted into CV1.

Sorry to revive an old thread.
It is normally against my religion, LOL, but I had high hopes that the solution offered in this thread would solve my problem. It didn't.
Here is my problem.
I operate with an NCE Power Pro 5 amp system. I have a pair of Athearn Genesis F3 units, an AB consist, with factory installed Tsunami sound decoders.
I had not run this consist in months, but last night I fired up the consist and started backing out of the station. At first, all went well, but within a few seconds, the consist stopped. I realized that the B unit was operating properly, but the A unit was moving slowly, effectively bringing the consist to a halt.
So, I killed the consist and tried to run each loco independently of the other. The B unit performed fine, but the A unit had issues. I no longer had lights or horn or bell although the prime mover still made sounds.
The A unit ran very slow even when I applied full speed (28 speed steps), and it would not stop on command or go into reverse. However, left running, it eventually responded to the stop or reverse direction commands. If I lifted one side of the wheelsets off the rail and put the wheelset back on the rail, the loco would respond to the command immediately, but still run in slow motion. Still no lights, horn, or bell.
At that point, I came upstairs and found this thread on the forum. So, this morning, I removed all other locos from the layout and followed the blast mode procedure that Crandell offered up earlier in this thread. That got the lights, horn and bell to respond, but the loco still ran in slow motion and failed to immediately respond to speed commands, stop commands and reverse direction commands.
I have tried this procedure several times. On a few occasions, I have been able to get the loco to run properly for a few seconds but then it reverts to slow motion and I lose the lights, horn, and bell.
Any suggestions other than taking a sledge hammer to it?
Rich,
Is there a brake feature that is somehow only being applied to the A-unit? Another thought is that momentum is at full-intensity on the A-unit and not the B-unit.
Perhaps try a complete reset of the A-unit and see what happens...

Thanks, Rich. Here's the sequence you want to follow:
That will fix your stubborn Soundtraxx issue.
richhotrainI had not run this consist in months, but last night I fired up the consist and started backing out of the station.
First question is if you have browsed your consists to make sure that the loco in question does not appear in some other consist.
Second question is how do you know that a mechanical problem of some sort has not happened. Can you unplug the Tsunami and just plug in a motor only decoder and see what happens?
Test the loco on DC - it would be really great if you could disconnect the motor wires fromt he decoder and just power the motor directly. See if it runs normally or runs in slow motion - you could have a mechanical problem, or badly congealed grease rather than a decoder problem. I have no Genesis locos but I can;t iamgine the factory grease is all that different from what P2K locos and Bachmann locos have - and some of my P2K locos have been in boxes for years and they will never run right until I completely clear out all the old grease and repalce it with some quality stuff.
Decoder reset would have cleared any oddball speed tables or any 'switching mode' option that would run the loco had half speed. So if it works fine with DC power but won't run on DCC, I'd suspect a faulty decoder.
selector Place only that one loco on your main track. Dial in address "00" on your active throttle. Enter 'programming on the main' mode, or what is called Ops Mode programming on that throttle. Edit CV8 to have a value of '8', and hit enter...or complete the reset by entering that value. SHUT OFF TRACK POWER! Re-power the tracks, and acquire address '03'. Try blowing the horn. Your loco will work on that address if you have not inadvertently locked the decoder.

Thanks very much! Soundtraxx's reset instructions did not work after
many attempts. Yours worked the first time!
Soundtraxx should modify their instructions.
