Changing Locomotive Address on Piko Decoder

I have a Piko BR 78 locomotive. ( ) My NCE DCC system works perfectly well for running the locomotive, but is unable to detect the decoder for programming purposes. I just want to change the locomotive address from "3" to the number on the side of the cab. Can anyone tell me how to do this?

    Dear Robert:
    Try to put the loco on your programming track, and change CV 1 to 78.

  • Dear Ulrich:
    Thanks but, as I said, NCE can't detect the decoder, so I can't change anything. The usual program commands cause the locomotive to move forward (!), but don't provide access to CVs.

    Just try to change CV 1 with programming on the main. Works with my Digitrax station.


  • Thanks, Ulrich. Programming on the main did indeed allow me change the short address to 34 and the long address to the desired 134, although only the short address worked at that point. I then found something which, while not a model of clarity, essentially says to change the CV 29 value to 46 to enable the long address:
    That took care of the problem.

  • That was my post at the other forum. CV 29 has to be calculated for the address you want to use. There is an on-line calculator here:

  • I have from Raynaulds brand new PIKO 52822 red shunting engine. The default address was 7 not 3 and while I can get lights and some sounds, the engine moves only in genuine shunting mode — very very slow. I tried reset. I must be missing something. No other new engine has done this. Any ideas? Thanks as always.

    Do you have a programming track? Programming CV 8 to 1 may only possible on the programming track. However, you may want to check CV2, CV5 and CV6 and see if they have a value other than 0.

    Thanks yes I have programming track. I will try what you suggest. Thanks as always.

  • Update - as usual (always) Ulrich saves the day. All fixed now. Thanks much.
