DCC- How To Reset Your Decoder back to Factory Default
Answers to DCC’s difficult questions.
My decoder appears to have died on line and how do I get it back?
Bob Ellis. aka PowerSteamGuy 1790, has provided us with some answers to the more difficult questions regarding DCC. You’ll need to explore his blog to see what all he shares. Go to: http://powersteamguy1790snewjjje.blogspot.com/2015/04/dcc-default-decoder-reset-values.html, of The New JJJ&E
Let’s say you get to a model railroad club and you discover someone else has programmed their locomotives to the same ID numbers you have. Not good. You need to know how to reprogram your decoders in the locomotive to new numbers. Most hand held control throttles have instructions on the backside that you can follow to make the needed change. You can also find instructions in the directions that came with the decoder.
Some anomaly is at work and manages to cancel out the decoder as in deprogram it. The decoder killing phenomena. A unpleasant realization when it hits your decoder doesn’t respond. In most cases you can save it by going back to factory default. I know this isn’t fun but necessary.
The most daunting question some of our local BVMR’s has is, how do you reset the decoders back to factory default? Your asking the same question, am I right? How do you get the decoder back up and operating….again! Order a new one? Trash it and go back to Analog DC? Yep, we managed to screw a few up and the good news is we managed to get most (but not all of them) back-up and working. Downside: We have one to many decoders that don’t respond and I fear we may never get them reset to factory default and operating again.. To many locomotives sitting on the dead line waiting for repairs.
Keeping in mind that DCC, is or will soon be old school technology. Now did I have to go and say that? No but it’s true! How old is DCC? Oh about 20 years old and getting older as you read this.
Most of us contribute the cause of non-working decoders to operator error. Ted Freeman contributes it to short’s either in the switches or on the layout. More on this in Shorts – Cause and Affect.
Programming on the main (when we don’t know how) and the infamous finger drag can wreak havoc. All without the aide of Mr. Murphy and those ever present Gremlins. I recommend you build yourself a program track and do your programming on the isolated piece of track. Get some experience under your belt and you can graduate to programming on the main. Cautiously!
Of course the manual that came with your particular DCC system, is the first place to look for answers. Most can be resolved by simply reading and following directions. I know who reads instructions?
Look for “How to reset your decoder back to factory default.” You will need to find the correct CV to zero out and then add in the correct number aka value into your decoder. IE., CV 19, is the key in most cases but because manufacturers made their decoders differently the CV and value may also be different. It depends on the decoder and how the manufacturer designed it.
Here are some values you may find helpful.
Manufacturer ID # In CV8 CV Value for reset. Lenz 99 CV8 = 33
NCE 11 CV30 = 2
Digitrax 12 CV8 = 8
LokSound (ESU) 15 CV8 = 8
Train Control System 153 CV8 = 8 or CV30 = 2
SoundTraxx: DSDLC, DSXTsunami 1141 CV 30 = 2 CV8= 8
MRC (New) 2143 CV125 = 1

I can only hope this helps.
