3 Overview
The VS-88HD is an HDTV compatible high performance matrix switcher 1
for HD-SDI and SDI digital video signals. It lets you simultaneously route
any of the eight inputs to any or all of the eight outputs. In particular, the
VS-88HD features:
Input and output signals on BNC connectors
A looping analog sync input with selectable sync signal termination
Switching synchronization, letting you synchronize to either the external
reference or incoming video
Equalization on each input
Each input button on the front panel automatically lights up when the
VS-88HD detects a video signal on that input
Switching according to the Bi-level or Tri-level Genlock input
The storing and recalling of setups
A Take button for the execution of multiple switches all at once
A 7-segment display
The VS-88HD, which is housed in a 19" 1U rack mountable enclosure, and is
fed from a 90-240 VAC universal switching power supply, can be controlled
via the:
Front panel buttons
Remotely, by RS-232 or RS-485 serial commands transmitted by a touch
screen system, PC, or other serial controller
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-88HD
away from moisture, excessive sunlight and dust
