Got my Rapido Turbo trains in. They run great, sound great, and look great. Only issue is I can't get them to take a four digit DCC address. I've tried changing CV 29, along with 17 and 18 to change it manually. I've tried programming on the main and on a programming track. It takes a two digit just fine.
Any tips / tricks?
Jason?

Are you programming cv 17, 18, and 29 in that order?I've tried that before, with other decoders, and if I program cv 29 first, the long address won't take.

Tried it, didn't work. I've got a request in with Rapid to see what's going on.

So to follow up, I wasn't thinking correctly. 4 digit address means a number greater than 128. When you're programming in 125, it's still a two digit address.

Anyone know why the dividing line is 128/129? |

Anyone know why the dividing line is 128/129? NMRA DCC Standard defines a short address to be 1 to 127 (bits 0-6 or first seven bits of CV1, standard states bit 7 must be '0'). If address is set to 0 decoder will use analog mode. Dividing line is actually 127/128. |
