@rplst8 posted:I’ve seen stuff like this happen when the R2LC board is wonky. It also happens with rev C07 boards. I think it has something to do with the serial data line. Also, I don’t know for sure, but I think something has to trigger the rev-up/down sounds. Some engines have a Hall Effect sensor, and others have a VCO circuit. Does the CC kit have something like that?
The R2LC could NEVER cause the CAB2 to not display some operating modes, the communication between the Legacy command base and the engine is strictly a one-way conversation. If the CAB2 is not displaying an operating mode, it IS an issue with the command base and/or CAB2.
