Changes

I contacted Maxon directly and their technical department emailed me a schematic for the out of production ACC-2016 interface cable. After making the circuit on a breadboard trying several times, and swapping TX/RX, I was not able to get the interface cable to work. Maybe you can, but I went for a more direct route.

** If you get things wrong and select a channel thats not programmed, the radio will flicker the red and green LEDs on boot. As long as you follow the black positions, you should be ok.

===Debugging===

Here's a table of the status indications showing what the radio is doing, from the service manual page 18. There is plenty of other information in the service manual for troubleshooting and fixing that would be redundant to cover here, so make sure you give it a read.
