Re: LMS-21

Have a Bachmann sound ready DCC equipped 50 ton two truck Climax that I am trying to equip with the ring system. When I access the the 21 pin board on the Loco nothing seems to happen. When I placed the loco on the track the lites came on an the loco starts running on it's own. Is there a compatability issue?. I even tried using a 21 pin to a 9 pin adapter and plugged it into a LM3-S and it did the same thing. Not sure if this will not work and will have to hard wire the Loco. Any help would be greatly appreciated. The loco is a Bachmann item#80601 if that helps.

Are you sure that it is DCC Ready and not DCC installed?

Looking at the instructions I could find on the web for this loco and a few videos, and I will admit that I could be wrong on this, it looks like this is a DCC installed loco and the 21 pin slot is just for Bachmann's sound module and not for a separate decoder. The circuit board itself appears to be the decoder from what I can see.

Looks like a hard wire, or at least a different mother board may be needed. This PDF from Bachmann might be of use in this process.

Thanks for the response KB,truly appreciated. I am technology deficient and after more research I thought that your description of the system was on point. I will now have to decide if I want to tackle a hardwire of the loco. At least it already has a speaker installed. I really wish that all of these manufacturers would follow the NMRA color code standards with the wiring, would make modifications much easier. Thank you again for taking the time to look into this issue.
