Sorry, I didn't explain well.
I am using two cables coupled together only to make a single cable which goes from tha interlink to single radio, my 9C (so that both ends have square plugs). I'm only using one radio to fly one plane, just like with the interlink controller.
I called RealFlight support and they didn't know and wouldn't say. I've checked the pinout readings with my multimeter and they are identical on both square ends with no crossover. Does the gmz4064 adapter change some pins around or is it same-pin to same-pin?
Or does something special have to be done to the 9C (I just got it and haven't had much experience) to get it to transmit through the cable?
Thanks, gm
