Hope some clever person here can help. I'd like to use a Videonics AB-1 to control a Mackie SDR 24/96 via the RS422 port. I've made the necessary 8-pin mini-DIN --> D-Sub 9-pin cable according to Videonics specs, and know that the Mackie uses the Sony "serial 9-pin" protocol. Tech support at Videonics is unable to tell me whether my scheme should work--they just suggested that I buy one of their ready-made cables (growl).
So I tried and failed, but I don't know why. Has anyone here actually done this successfully? Any help would be greatly appreciated!
