G.P.I. Connector Pin-Outs
The Shortcut Editor may be remotely controlled through a 15-pin "D" connector on its
rear panel. Remote functions are asserted through a switch contact to Ground. If desired, a
"tally" indicator light can be wired to show that a function has taken place. The lamp is
controlled through an output on the same connector. For convenience, +12 volts is provided on
the connector. This may be wired through the lamp, and then back to an appropriate pin on
the connector. See page 19 for instructions on interfacing to telephone control systems.

G.P.I. CONNECTOR PIN ASSIGNMENTS
Setting LED Current
The operating current of an external tally LED must be set with a current limiting
resistor. Given a +12 volt source, a resistor of 910Ω or 470Ω to will provide LED current of
10 mA or 20 mA respectively. A _-watt resistor is suitable.
GPI Input Assignment Options
The GPI Inputs can be assigned in five configurations. The default is FF,REW,STOP,REC.
Play remains Play in all configurations. The second option is PAUSE,REW,STOP,REC which
changes the FF input to activate Pause. This can be valuable to allow consecutive recordings in
the same file without editing or insert recording. The third option is HK-1,HK-2,REC,STOP. The
fourth option is HOT-KEYS 1-3,STOP. The fifth option is HOT-KEYS 1,2,3,4. The Tally outputs
follow the functions of the reassigned inputs.
