Hi IT,
You may be right and the TCS decoder may have that function but presently I cannot reprogram CV29 and cannot check:facepalm:
If it was DC compatible I wonder why to would have been turned off or why it would come with CV29 set to non-DC running as default
The decoder is in a DMU with a function decoder in the dummy car. Neither works. They're hardwired, I think, so not easy to remove. Maybe it really just isn't just compatible? I'll try to check the TCS website again. Seller says it's not DC compatible and I think he's on the level
