Question

Have you tried resetting the decoder to factory defaults? Did it come with the magnetic wand to reset the internal reed switch? I have a similar problem with P2K GP7. The loco happens to be numbered #102. When I set that loco's address to 102 it stops moving, but the sound works. If I reset the loco to factory defaults it responds again. Haven't been able to figure that one out yet. But leaving it at the default address of 3 has been my solution for now.

 This one didn't come with a

This one didn't come with a wand, but that's a good idea. Thanks.

I can re-program the address, and I have tried 3 and 200. The system reads it back fine after I change it, so I believe it is programming. I'll see if I can find the CV to reset to factory tonight.

OK, so there's a wand.

 Walthers called and said the best approach is to put the engine on a DC test track, hold the magnet over the correct position, and bring the power up slowly until you hear RESETTING. I guess the wand must have fallen out of the box.

Maybe it ran off somewhere with my old DC power pack.

Chris, You can reset the QSI

Chris,

You can reset the QSI decoder to defaults if the wand is not availlable with these CV's,  Est to be in OPS mode so the decoder has power during the full reset process,

You can write 113 to CV56. Once you hear three horn blows, the reset has completed.  Other way is again in OPS :

1- Set CV 49 = 128

2- Set CV 50 = 255

3- Set CV 56 = 113. 

Again it should respond with three horn blows.

Kevin,

You mentionned this issue of yours  before and it got me thinking.

If you are running a Digitrax Comand Station, try and clear your ' slots'  of all information. You can do this reset via  OPSW 36 or 39.

 When you  reset the decoder to defaults and then put it back to '102', this does not change the 'slot' assignement. The command station retains  what values it had for  decoder  '102' in a slot and the engine ends up taking exactly the same slot.   So you can end up right back to the same issue.  So try clearing the slots, reset your decoder, set it back to 102 and try it. This is a simple process if you are running DecoderPro. But I prefer Loconet Checker for Slot management/clearing as it  does a better job of it.  You get more information from Loconet Checker, in regards to slots. 

I suspect NCE and other  DCC command stations  use the similar principal to keep the decoder information alive from sesion to session.

My Hero!

Marc, thanks for posting this. Would have never even thought about this issue. While I'm running a Lenz system with Decoder Pro rather than a Digitrax, I will check this out and see what happens.

Much thanks for the help again!

Those darn magnets....

They have a habit of sticking to things too!  If by some reason you can't get anything to work and can't find a suitable magnet, let me know. I have several of those magnetic wands hanging around. Would be happy to send you one.

Thanks, Kevin

Thanks for the offer. I've got two more of these still in the box, so I'm sure I'll dig up a magnet. I went a little crazy when Life Like came out with the Phase I GP9 because the Camas Prairie had 10 of them, and all the NP numbers were correct for the railroad.

Don't blame you at all

Anytime you can get locos out of the box correctly numbered and ready to go, it's a huge timesaver! Not that I know what that's like since I'm a freelancer.

I saw that you were modeling the Camas Prairie. Very near my old stomping grounds as a kid growing up. Very interesting line and always thought it would make a great subject to model. Looking forward to seeing your construction continue Chris.

Eastern Washington?

 I was just up there last summer. I figured you were from the wet side of the state.

The Camas Prairie is a great railroad with all it's mountains, tunnels and wooden trestles. Unfortunately, with no basements in Texas, I have about the space you do, so I'm sticking to modeling Lewiston, ID for now. Someday I'll get back to it, update the website and show some progress on the new railroad.

Good to go!

 Finding the wand was the easy part. Finding a DC power pack turned out to be a little harder.

Once I procured an old MRC, I was able to reset the geep and everything came back to life at address 3.
