VIDEO DETECTOR/SWITCH
MODEL VDTR1
The VDTR1, Video Detector and Switch, will detect the loss of video on the A input and automatically switch to the B input. The video detector is based on digital signal processing of the A input sync signal. If the A input has excessive noise, missing or intermittent for over 100mS the switch will occur. Momentary losses for less than 100mS are ignored. While the B video is selected the A input must be solid for 100mS before the unit will switch back to the A input.
The automatic detection can be inhibited from the front panel and either input can be manually selected.
A status contact closure output is available for remote status from the rear panel with a quick disconnect connector. Both normally closed and normally open contacts are available. The normal state is the A input selected.
Up to 3 units can be rack mounted in a 1 Rack Unit space, 1.5 " high, using the optional rack mount assembly.
