2.

Troubleshooting
Note that the source of video cascaded is determined by each upstream card’s On Air Control -
Key 1 source selection.
If the source format doesn’t match, or if the On Air Control - Key 1 source is set to something
other than Inputs 1-4, then an internally generated black signal is output.
Switching the source is not timed. Changes between the input sources and black, may cause
downstream equipment to temporarily lose lock and/or show corrupt video.
Monitor the Signal Input timing fields on each card to ensure that all signals are synchronous. An
asynchronous signal may vertically scroll or glitch if put on-air.
