GRJ, I think I have stumbled upon issue. I believe it to be the cab-2.
I used the LSU and reset base and cab-2 as delivered.
I then used the V1.53 update modules on both cab-2 and base all shows on cab2 as being V1.53 on both.
I then added the BB engine module into and updated the cab-2 all was working except the background sounds so huh unlike most men I read the legacy book and using remote pushed aux-1 and then volume up key and there the sounds were.
I then edited in LSU so tender on/off buttons were selected and saved the changes.
I then powered up BB and all features were working tender lights on/off each button press.
But after setting background sounds volume the tender lights and smoke stopped responding to button presses.
so I powered BB down and turned cab2 off, and then using the tmcc cab1 I started the BB up and all works I can turn smoke on/off at will sure wish it had a tender light on/off.
so I'm certain the issue is not the BB but rather the cab2 key as if cab1 will work all then?
I hope to call lionel monday morning and see what tricks they have or if a return RA # is needed.
one question when you reset base to clear all settings does it not also clear all engines and the information also.
reason I ask is on cab2 even though info is gone other than engine assigned numbers I accidentally switched to a engine id# and the engine responded!
or are the engine id# not cleared so an engine that has the corresponding number selected will still power up?
