QSI Q1a Sound Decoder problem

[upinct]

Posted this on another forum and didn't get a response so thought I'd try here.

I have a Atlas Gold Series GP40 that is giving me fits. Maybe I missed something. First a little about my set up, running a DCS51, programming using JMRI with a PR3 and PB-100, Program track is connected to the PR3 through the PB-100 and a loconet cable connects to the 51 through the PR3. Worked great for Tsunami's and TCS and Digitrax decoders. I was able to program the GP40 the way I wanted and the file is still saved on my computer. I changed to the long address and programmed the address among other changes. Loco took all my programming correctly. Somehow the loco became non-responsive. Did the double click of F6 and it came back. Sometime later the loco really became non-responsive and F6 double click did not work.. So I decided to try factory reset according to manual which is

CV 49 to 128

CV 50 to 255

CV 56 to 113

Okay now GP40 is back to factory settings and responds on address 3. Lights, sound and throttle all work. But, every time power is reapplied from powering off the Decoder says out loud "reset". Now I can't get it to program at all. It will read back CV's and its address but I am unable to write changes to it. I unplugged the programming track from the PR3 and plugged the PB-100 directly into the programming output of the DCS51. No Joy. Tried blast mode on the main and did remember to toggle on sw 7. Not able to program on the main. I guess my next step is to try a reset using the magnetic wand it came with but before I go digging out a DC power pack for the procedure to reset with the wand....

What am I missing? Any insights would be welcome. Been programming for a while now with this set up and have not had an issue. This is my first QSI decoder.

Thanks in advance, Derek

A call to QSI service could help you if no one chips in here. They have been very helpful to me in the past.

I had one that suddenly decided to switch to analog mode all on its own. I had to dig put a dc powerpack and my magic wand to reset it. After that, I could program it with DCC. One of the things I did was disable analog when I reprogrammed it

Thanks Guys.

Terry, I thought I might have to do the wand trick before I posted. Just wanted to see if someone saw something I was missing before I go hunting and dragging out my DC power pack.

I'll try the wand trick Saturday before getting on to service.

Thanks again, Derek
