External interfaces
This unit comes with three connectors to support four
external interfaces: a GPI input connector, RS-422A/RS-232
(9-pin) connector and a Tally output connector.  Select the
connector that suits the editing controller model used.
GPI
(general purpose interface)
This enables the use of auto takes with the GPI output of
the external controller.  At the fall of the GPI signal, wipe/mix
set on the panel or DSK or Fade is executed.
RS-422A
This enables the AG-A850 external editing controller to be
connected to the unit and the VTR to be controlled from a
remote location.

Support for the editing controller is shown below.)
Connections
1) Set the RS-422A/RS-232C selector switch to

<Notes>  Editing using the RS-422A, RS-232 and GPI
interface connectors
The commands are received and then executed 3 frames
later.
If, while the 3D optional board is installed, the 1-Frame
Dly mode has been selected by the system 1 settings
(see page 56) on the “Setup” initial setting screen, the
pictures and sound from the source are always output
with a 1-frame delay.
When selecting a DVE pattern, set the transition time to
more than 2 frames. No guarantees are made for frame
accuracy if the time setting is lower than this.
Tally
An open connector is provided for outputting the tally lamp
signals.
