Re: Just to be clear. What pins are for CAT?
There is no CAT control on the DRAWS hat. The mini DINS are for the input/output of digital audio. You can attach two radios hence two connectors. CAT is done by a USB to CAT cable for your radio. You need to provide that cable.
I was totally lost until I found a great series of videos starting at https://youtu.be/u6wz2kZJ5Vo
These five videos take you calmly through setup step by step. That guy deserves a medal.
All the best
