Have an Atlas GP40-2 with with a 2008 QSI sound decoder. Am running a Hornby elite controller with a PTB-100 programming booster. Usually program CV's on a dedicated programming track with no issues but it can't read the CV's on this model.
Seems like operate mode on the main works and i can change the address to 63 and the loco reads back and confirms it but the next time i put it on a live track it says reset and goes back to no.3
also haven't been a able to find how to adjust the volume down
appreciate any advice

thanks for your info but it it seems to program ok and reads back the changes but the next time it gets power it does it's own reset and puts settings back to factory

When the DCC track power is turned on does the loco respond by saying "reset" even though the magnetic wand is not being used? (Assuming the verbal confirmation option is not turned off.) If this is the case then the magnetic reed switch on the decoder is stuck in the closed position. It will need to be replaced. The reed switch is also used to adjust the sound volume so a faulty switch would also explain why you can't lower the volume.

yes after making any adjustments it verbally confirms my changes and then the next time i put it back on the track without me doing anything it says "reset" and it overwrites my changes Can u just replace the reed switch or does it mean a new decoder

Hi, I would just throw the decoder out. It is at least 12 year old and design wise even older. I always go to the site from TCS to see if they have an conversion done. In this case you can find the installation of the WOW-Sound set in an Silver (non-sound) version. tcsdcc.com/installation/ho-scale/655 You have already the soundversion, so a speaker (even two) should already be there. Looking at the space you cannot install a Atlas style board directly on the studs. The speaker housing is to big. But you stil use that board style decoder. Just remove the studs on the motor support. Personally I would add a new ESU LokSound 5 Direct but I have the ESU LokProgrammer and can easily programm my own decoder with the soundfile I like. Alternative is a Tsunami 2 or if this is your first conversion the TCS WDK-ATL-5 kit. Yes, you get a speaker to much but that isn't the most expensive component. Best regards, Gino |

thanks for the advice Was hopeing i could do something to save the decoder as they are pretty expensive here for sound decoders. It still works if i leave it at no.3 just the volume is very loud.
rgds,

If you want to try one more thing before major surgery, or giving up, you can try programming the address in OPS mode on the main, using the CV17+CV18+CV29 method. Ruppweb has a tool for calculating the values. |
