Chrisr40 Posted January 28 Share Posted January 28 Hello all I bought a loco yesterday that is unresponsive (loksound 3.5) but I can read cvs. I tried changing the address but no joy. I think it may be set to long address as cv 29 is 38 but how do I work out what the long address is please ? Link to post Share on other sites More sharing options...
Nigelcliffe Posted January 28 Share Posted January 28 CV29=38 is a long address (see calculator also referenced below). 1) Check its not in a consist. If CV19 is anything other than zero, then CV19 is setting the consist address. Change CV19 to 0. 2) Assuming your system has a programming track, the consult the system manual on how to read the loco address. Most have mechanisms to do this for you. 3) If your system cannot read on a programming track, then use "service mode programming" to Write the address you'd like, following the instructions in the system's manual. This will overwrite any address currently in the loco. 4) If you want to work out a long address manually, the you need to decypher CV17 and CV18. See calculator I wrote over a dozen years ago. But you shouldn't need this. Link to post Share on other sites More sharing options...

Do I need to do anything with that as reading it now just returns what I set it to ? Thanks Chris Link to post Share on other sites More sharing options...

Thanks Chris Have you read your system manual on how to set addresses ? Most systems have a command for setting addresses. If you're going to set things manually, then you need to set CV29 correctly as well as setting CV1 or CV17/CV18. The text around the calculator attempts to explain how they all work. 1 Link to post Share on other sites More sharing options...

RMweb Gold BoD Posted January 28 RMweb Gold Share Posted January 28 I am puzzled as to why you don’t (as Nigel has suggested) just read the current or set a new address using this facility on your DCC system, assuming this facility exists on yours.

Hello, because I changed it to a different number from what it was originally. I hadn't made a note of the original address which is a lesson learnt. But either way it emerges that it is indeed set up for a 4 digit ( I have only ever used short addresses) long address so I overwrote that and now all is well so thank you for your help Nigel.

RMweb Gold Dagworth Posted January 28 RMweb Gold Share Posted January 28 Change CV 29 to 6. That will disable the long address and make the short address in CV1 the address is responds to Andi 1 Link to post Share on other sites More sharing options...
