I posted on the MRH forum about putting a decoder in a Bachmann GP30. The MRH community gave several helpful responses.

As you may be aware, I purchased a Tsunami decoder. All was good - I had the decoder wired to the motor (after
discovering I had the motor wired backwards) and the frame and hooked up my speaker (in an enclosure) and I got sound and the loco ran. No lights yet - I wanted to test things as they were.

I think the sounds are too loud and I was able to program on the main using my Digitrax DCS100 (my now old Chief II set), JMRI and a LocoBuffer-USB. I know the use of the programming track is pointless. Somewhere in my programming delirium I screwed up something big time. The sound came on when the track is powered but I could get NO response in any other way. I think, but I'm not sure, I mangled the addresses and didn't know how to recover. Without knowing the address I could not communicate with the decoder. 

I have spent a good bit of three days trying to find a solution. No good ideas from the SoundTraxx or Digitrax web sites. After wading through the Soundtraxx Yahoo Group and then going to the Digitrax Group I found the key. They were not discussing my problem specifically but it gave me the solution. I found a reference to this page on the Digitrax web site:  http://kb.digitrax.com//index.php?a=1162  It gave me this:

 

Resetting a Locomotive

If you don't know the current address and need to reset the locomotive, place the locomotive on the main track WITH NO OTHER LOCOMOTIVES ON THE LAYOUT. THIS IS IMPORTANT as you will be sending a broadcast programming command to every decoder on a live track!

1. Select address "00"

2. Enter Operations Mode programming

3. Follow the manufacturers instructions for programming a reset [This will vary from manufacturer to manufacturer. Editor].

4. Remove the locomotive from the powered track. When it powers up again it should have reset to address 3.

 

Make sure there are no other locos on the tracks and select loco ID 00 (zero zero) then use the Digitrax throttle (mine is a DT400) and set program in Po (ops) mode. You can then set the Ad2 and Ad4 addresses. Programming address 00 on the main will broadcast to any mobile decoder on the tracks.

This solution does not require you to know the current address of the decoder. It worked perfectly for me.

I hope this is useful information for someone else. Maybe everyone else will just go "DUH!!" If nothing else it will be here for others to search and find.

Program track time

Ken put it on the programing track and fire up the Decoder Pro.  Use the read type from decoder tell the programmed address.  This can walk you through the steps  http://jmri.sourceforge.net/help/en/manual/Programmer_Start.shtml

Program track...

Steve,

Thanks for the comment. However, Using the programming track did not work in any programming mode. That is why I was beginning to run around like a chicken with its head cut off. To use the Programming Track you have to use something like the Digitrax PR3 to boost the power to the Tsunami to get any response and/or, in my case, program the decoder. The ops mode programming (programming on the main) will let you use JMRI DecoderPro to fully program the decoder (except the address you are using). The trick for me was using 00 for the address. I suppose this is what some people have called burst mode. I never saw "burst mode" defined in any posts anywhere I looked.

Anyway it worked for me.

Thanks again for thinking about the issue.

Burst mode definition

I'm no expert, but as I understand it, burst mode means using the main line at full power as though it were a programming track.  In a sense, it achieves the same thing that you did, but by a switch inside the command station instead of accessing a specific address.

I like your solution better - it's easier to remember.  One thing, though.  Did you have to figure out the codes for CV17&18, or just program the address as you normally would?  I've wondered if you could read & write CV 17&18 on the main in ops mode, and then set CV29 to use 4 digit addressing.

Normal programming

I think, not sure, that the ops mode programming is done with the track at full power. I believe that is why I can program the Tusnami on the main and not on the program track. You generally send data to a specific address with track power on. Using address 00 hits EVERY decoder on the track. That was the key to solving my problem. I did a "factory reset" (CV 8 to 008) to begin with. That set the Ad2 back to 03 and then I could do the programming at address 03 to set Ad4 to the loco road number. 

At least that is what I think is going on, your mileage may vary. From my scanning through the SoundTraxx and Digitrax Yahoo Groups, I think the programming track results vary with each individual decoder.

Blast mode

"Blast mode" is a documented feature of the Digitrax Zephyr Xtra (DCS51) and an  undocumented feature of the old Zephyr (DCS50).

It puts full power to the programming track.  It should be noted that when this mode is used programming is also sent to the main track so everything with a decoder needs to be removed from the track (or somehow electrically isolated from the command station).

My bad

Sorry Ken I thought you had a Zephyr.  The problem with programing on the main is you can not read back CVs like a the programing track.  To add enough power you may want a Power Pax like this from MRH sponsor Litchfield station

This also might help in the mean time

No problem

No problem Steve! I didn't specify my DCC system and I should have. In fact I think I will edit the original post to add that info so anyone searching the for Tsunami programming help will have that info.

Right now I'm good with programming on the main for the loco with the Tsunami. I only have 2 other DCC locos at the moment and I have been able to use the programming track with them. At some point in the future if I have both more locos and a larger layout (2' x 8' shelf now) I would consider something like the Power Pax.

Thanks for your responses!
