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.

<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.
