Control Using GPI Signals

You can combine the DFS-700/700P with any editing control unit capable of GPI signal output to carry out A/B roll editing using two players and one recorder.

You can use one GPI signal to execute DFS-700/700P effects, and a second GPI signal to turn the downstream key function on and off.

Preparations

Make the following preparations to control the DFS-700/700P using GPI signals output by the editing control unit.

For details about operation, refer to the manuals supplied with your editing control unit.

On the DFS-700/700P

•In page 1 of the setup menu, set F3(PORTS) to “GPI”.

•Press the EDITOR button on the control panel, turning it on. (This button is lit when the DFS-700/700P is powered on.)

On the recorder VCR

•Set the recorder VCR so that it enters PB (playback) mode when stopped. (If the VCR has a selector for PB or PB/EE, set it to PB.)

•If the VCR has a built-in TBC, set the VCR to DELAYED SYNC mode.

On the editing control unit

•Set the GPI signal output timing to 3 frames before the IN point.

•Set the GPI signal pulse length to at least 1 frame.

Notes

•To display the background image during or after a transition, press an appropriate BACKGROUND bus button on the DFS-700/700P.

•Because the DFS-700/700P has a built-in frame synchronizer, output of player VCR edit points set on the editing control unit is delayed by 1 frame, so that recording begins with the previous frame. However, recorder edit points are not delayed. For example, if the IN point of the player VCR is set to 00:00:10:15, recording begins from 00:00:10:14.
