Title: VIDEO LOSS INDICATOR
Category: A/V Baseband Products
Industry: CCTV/Security, TV/Radio Broadcast, CATV Cable Industry
The AVI473V Video Loss Indicator provides an independent form C relay contact closures for loss of video service. This contact closures can be used to operate an external program switch or remote maintenance alarm. The unit has an audible alarm sounder that can be separately field programmed for video loss.
The video signal loops through the unit so that signal transmission is not lost if power is removed from the AVI473. A field programmable video alarm delay can be set to prevent false alarms caused by short duration sync loss, non vertical interval switching, or any other momentary loss of video.
This unit uses PLL “Phase-Lock-Loop” technology to prevent false alarms due to high level noise. This is especially useful on satellite feeds and microwave transmission, when loss of video produces high level noise. The AVI473V will operate in high level noise environments. A red front panel L.E.D. indicates the loss of video.
The unit fits into the RMS-400 mainframe and power supply. Up to nine AVI473V units can fit into one RMS-400 mainframe.
