Been working on a 5022 head and built this up over the weekend. It’s a ten pin break out box that can go between the radio and amplifier or the radio and the control head. Allows you to look at things like the +24 volt bus, control, ALC and data lines between the radio and amplifier or the +24 volt bus, data to and from the head and audio between the head and radio, also makes it easy to run the head with it open for diagnostics. Shot some video of it and will try to get that up soon.
