To configure PowerScript’s Internal Key downstream from a switcher:
1
Connect the Preview monitor to the PREVIEW OUT connector on the PowerScript rear
panel.
2
Connect the Video Feed (such as a signal from a mixer or switcher) to the VIDEO IN
connector, also on the rear panel.
Optionally, connect the video distribution channel or the VTR to the PowerScript VIDEO
OUT connector.
Also optionally, connect the VTR to the Program Monitor.
3
If you want to use a GPI device to trigger events, connect it to the GPI 1 and/or GPI 2
connectors on the PowerScript rear panel.
Turn to “Completing the Setup” on page 26 to configure PowerScript to use two separate
monitors for Preview and Program, then complete the required steps.
