Good morning Mark,
I have 3 TCS WOW-121 Steam Decoders. I think they are very similar. Sometimes hickups can happen on the rails
and the decoders can sometimes interpret them as programming commands. I have been "LOCKING" all of my TCS WOW-121 Steam Decoders.
That way they are locked and will NOT accept any programming commands. When the time comes and you want to make programming changes
to the decoders you can then unlock them to make the CV changes. I know this doesn't exactly answer your question right now
but it might avoid some future problems down the road.



Good luck!
Tim
