I have a digitrax empire builder system. I seem to be having trouble establishing a loco number for my new challenger. It will run well on the factory default of 3, but what if I want it to be different? Any ideas
Go into programing mode on your throttle and set for programming on the main (ops mode) Set cv29 to 38 Now you have to work out what cv 17 and 18 need to be set to. Go to http://ruppweb.dyndns.org/xray/comp/decoder.htm and type in the address you want. It will automatically calculate CV 17 and 18's values. For example, cab No 3985 will have CV17=207 & CV18=154. Now set CV17 & 18 to these values, exit programming mode and dial in your new address. Hopefully this will get you going.
trainlady12, do what Phill said. Or if you only want to reset the loco number to 2 digits it is a little simpler. With the loco on the mainline, with track power on and loco address 03 selected, press Prog key until Ops appears, then these steps: Press Steps CV key Press Loco key until AD2 appears Press Steps CV key again Enter desired 2 digit number using keypad Press CV WR key Press Exit key This should do it, at least it does with a Digitrax decoder. Let us know if you have a problem. Ben
CV29 = 38?? I thought the highest possible was 37 ?? :confused2: But I'm no DCC expert either, so I could be wrong .. in which case I'm learning something new. :w20z6q:
Can't answer that. The instructions for some MRC decoders caution against the average user trying to program CV29. This may vary with each decoder but is something that ladytrain12 should consider. Resetting to a 2 digit loco address might be prudent. Ben
Have a look at this table: http://www.tonystrains.com/technews/cv29-lookup.htm You can program CV29 from 0 to 55
DUH!! I'm a DUNCE :embarassed: ... I should have recognized what's being talked about. You are listing the "decimal" number for programming CV-29 but not including the "hexi-decimal" number. CV-29 can be programmed using either hexi-decimal 0-37, or decimal 0-55. Or in this particular instance: 38 decimal = 26 hexi-decimal. oh5qn: :yes9rq:
