Adding TMCC to my Mth TIU

TMCC wire goes to the Black posts on the TIU, which is the Common, two outside rails.

Sounds like you're  saying   the  TMCC??   base or  TIU/TMCC cable?   is shorting out your Z-4000.

If you can run proto-2/ 3 engines using fixed 1 on the tiu  and you now want to run TMCC with a  cab-1 , all you need to do is run a wire from the "U" connection from the LIOnel command base to an outside rail. Does that work?

 If you're trying to add TMCC engines to the DCS remote well that's  a different story.

I don't think it says anywhere to put the TMCC ground to a Positive Tiu  output.    Put it on a Black connection.

Sorry I meant I did put it on the black output on my tiu. Mth remote does not recognize tmcc engines, even as going through all the software instructions. Also my red light on my Mth 4000 comes on erratically 

Wondering if my TIU is working correctly. I did have a train shop repair it previously.

I don't know what to think.. Maybe try and figure out why the z-4000 is shorting out with just a simple loop in conventional mode.... No tiu.

If that works fine, try adding  DCS with the TIU and see how that goes...

And I guess the last step would be hooking up  DCS /TMCC using the proper cable and Lionel command base.

 TMCC engine have to be added manually, Give them a name, then  "D" for done and then the list of TMCC address shows up and you add the TMCC address. That's  the one that you address the engine using a cab-1 .    Engine will be in the inactive list. good luck.

Thanks, it makes sense, starting from the simplest and add as I go along on a test loop.

I have found that adding a TMCC through my DCS remote works if I program it manually, then edit the address of the engine to another number than the 1 assigned, then it magically appears and runs very well using the DCS remote.
