Atlas O TMCC Dash 8 Help Needed

I don't know much but maybe these will help?

All TMCC engines respond to EngineID 99 regardless of what is stored in the engine. Try using 99 and see what happens.

I could be wrong, but I believe all LEGACY equipped engines will respond to a "99" address, but not TMCC equipped-they were all just delivered with a "1" as the initial TMCC ID.

It makes no sense why it operates as advertised in Bill's shop, but not on your layout. Do you have any friends nearby with TMCC/Legacy layouts (or a local hobby shop) you could try this particular engine on to see if it runs in command on their layout?

Could it be responding to a cab1 and not the Legacy cab 2 remote? Maybe Atlas tried it with the cab1? I'm guessing that the OP only has a cab2, right??

Anybody nearby to you that could test it for you?

I'm out of my league here, but I find this interesting. I run mainly DCS with a few TMCC engines and a cab1.

Hold the trucks and shake it. If you hear something rattling, chances are the antenna fell off the shell. Its only held on with a dab of some junky glue. If it falls off, it lands on the boards and can short something out. I had to replace the R4LC in mine because the antenna dropped off the shell and knocked it out. I reattached the antenna with outdoor 2 sided foam tape.

It would run, but not in command. Just a thought from experience. 

Its not too hard to open it up. Wiggling the R4LC out with all the wiring in the way was doable but a little touchy.

When setting up my Atlas F-Units on the Legacy Remote. Set them up under R100 rather than TMCC or Legacy. Also set for Rail Sounds 5. Hope this helps.

Thanks for the help guys! I just needed to have the Legacy remote set to TMCC mode. You guys rock!
