No thanks
always try to help everyone here if i can.
I am not sure if the PMDG one will work the problem is maybe that they have writen there own software for it and than it will not match with the rest but i dont use it so i cant tell you. I know in the past i also had problems with communication when i used a 3 part software of planes... all i know is that it works great when you use the PM cdu software. But maybe someone else knows that here?
Your other question.. the package contane the hardware cdu inside there is a pcb already wired up and the keys are illuminated automatic when you power your adaptor on it ( just pay attention about the volt what i mention before)
To let the keys also send keystrings Peter provide a small pcb with it that you on one part connect to the adaptor so the cdu light up and on the other side you use a USB cable ( also in the package) that you plug into your computer. The computer automatic reconize the new USB cart.
You already can than if you have the software of PM use it and see the results on the screen you run PM last step will be than the monitor behind your cdu as i also mention before.
If you are at that part let me know because there are some details to be done to get it all working proper but we can help you out as well in that
here a pictures ones again of how it looks now here...
