To connect an unbalanced input, connect the signal to pin #8 and connect the
shield to pins #15 and #7.

source directly, use the following interconnection cable.
Pin #14 of the DB-15 accessory connector pr30 VDC to power the
external device. Connecting pins #7 and #15 together unbalances the program
input. The output from the party line device is connected to pin #8 with a
1KOhm load to provide a partial termination.
