A search of the forum and Barry's book shows a huge volume of information about connecting up the hardware to make TMCC control from DCS possible. I have acquired a BASE1L and hooked it up and it works as advertised.
What I haven't been able to find is much information about the software control (softkeys) from the DCS remote (or app) of TMCC.
I am normally one to "play around" with software, but I've done a bit of this with the AX key and have made my engine (6-18295) go dark and have had to putz around to get it back online. I know AX and the 2 button runs cab chatter successfully, but that's about all I'm willing to do at the moment.
Does anyone recall any topics on the forum or other sources of info about this??
