I am struggling to recover from making a mistake in programming a minitrix RAm TEE sound decoder. It reads as a 131 (minitrix) version 5, and was brought to me as being extremely slow in acceleration or deceleration. The sound/lights worked OK. On my NCE Powercab I simply set the momentum to zero and this solved the problem, at least for a while. Without doing any other adjustments, it reverted back to being extremely slow in acc. and dec. . The momentum commands would not work any more! Previously I had reset one of these RAm TEE units (which had a loksound on board) by resetting cv 8 to 8.(On the programming track) Thinking it was the same decoder I did the same to this unit, but the result was the whole decoder does not respond to anything! When I read cv 8 on the programming track it reads 131 as if it has not been altered.
I have the booklet that comes with the unit but there is no factory reset mentioned. I have checked the cv's against those given and they read as they apparently should. When programming on the main cv 8 reads 5 but the book does not give any data for cv 8.
Has any one any suggestions, please?
