Starting new thread as previous thread had too many different ideas going on.
Revision I TIU (DCS version 5.0 on both TIU and REMOTE) powered from Z4000 to FIXED IN. Then FIXED OUT to track. Red to center rail; black to outside rail.
TIU blinks once; Remote set to TIU 1.
RESET REMOTE AND TIU.
READ finds TIU 1 and no active engines.
Tried to add DCS engine that I know works. NO ENGINE TO ADD.
How do I get this set up to add engines?
