I believe you don't really add any TMCC engine to DCS. You create an address that talks to the TMCC engine. So when you say you can't add it, either I'm wrong about what I'm saying, or... you mean edit the address? or add the slot to the DCS remote?
Now about the cab 1, you just assign an address to the engine's board. You can't add anything to the cab 1.
So we are just talking language here right? You have other engines so you must know about them already.
So you have an engine that is bricked and won't let you assign a TMCC address to it. You obviously know to put the engine on powered track and set the switch to program. How's the batteries in the Cab 1? Does the light on the TMCC base blink when you push anything? Can you edit another TMCC engine with your set-up?
Have you reset this engine with your Cab 1 yet?
I think you need to post this in the TMCC column, or get the Lionel techs to see this here and respond.
Appreciate the replies and finally had a chance to work on engine again this evening. The engine is an Atlas Vermont Railway RS-3, maybe 10+ years old?
When I added to track tonight and added power using Variable channel, it would start up upon power being added to track. However, horn, bell and directional were non-responsive. It would remain in place, however, engine would rev up.
I finally hit emergency stop on my DCS which shut it down. Now, I am unable to add it using DCS or CAB-1, going through various steps to add in a new engine. I have 8-10 other Lionel or Atlas engines that operate flawlessly so I’m not sure what is going on here.
