Non-Sync Status
You can check if a video signal into a MultiProcessor Input, selected on a source bus, or the video outputs of the switcher, is synchronized with the switcher reference format. The Non-Sync indicators serve as a warning only, indicating that the timing of the input should be fixed at the source. If the source is non-synchronous with the switcher reference format, cuts, dissolves and other effects can still be performed, but the source is shifted vertically.
If a non-synchronous source is selected on a crosspoint bus, and the non-sync detection feature is turned on, the crosspoint button flashes, indicating that the source is mistimed.
Refer to Non-Sync Detection for information on turning non-sync detect on for a source.
