When changing the address, did the loco jerk a little? If not the command to the decoder did not take. What DCC system do you use? Tsunamis can be tricky to change the address on. Try a test: does the loco move on the new address? If no it didn't take. You have to have the loco address on the throttle to work the functions for that loco. Joe
The loco jerk fine. Just as I am used to it. In some cases only one little step sometimes 4 or 5 steps over 2". That looks as usual to me. It did also take the new address in each case. Just some other CVs might have been effected too.
CV1 = 5 changes "something" I could not find but the lights are off. CV1 = 1 resets the low order bit of CV 29. That is easy to find :-)
I assume the Uhlenbrock Intellibox II (a German product) is not designed to work with Tsunami decoders. It is pure luck I can read and write most CVs without problems.
