I am looking for the diagram for the pin assignments of the Futaba round DIN Trainer plug on the Polks Tracker III. I am trying to make a plug adapter to use with the Fatshark Goggles for use with FPV video flight. The mini DIN plug used for Fatshark goggles has to be custom matched to the older Futaba DIN plug on the Polks transmitter. I need to use a pos, neg, and a PPM connection.

I tried to connect to Aristo Craft but the link is dead. Any help from you guys is appreciated.
