Overview
The Kramer VS-81HD is a true 8x1 switcher for standard definition / high
definition SDI signals that lets you switch any one of the eight inputs to two
identical outputs.
In particular, the VS-81HD:
Features selector buttons that automatically light up in different colors—
green, when the VS-81HD detects a 'standard definition' signal, or blue,
when it detects a 'high definition' signal
Features reclocking and equalization on each input
Supports cable equalization and is SMPTE 259M, 292M and DVB-ASI
compliant
Supports ANC data (embedded audio, Teletext, time code and so on)
Switches according to the Bi-level or Tri-level Genlock input according to
SMPTE RP-168
Has an OFF button to disconnect the outputs
Has a front panel lock button
The VS-81HD, which is housed in a 19" 1U rack mountable enclosure, and is fed
from a 100-240 VAC universal switching power supply, can be controlled via the:
Front panel buttons
Infra-red remote control transmitter
Infra-red remote extension cable transmitter, see section 4.1
Remotely, by RS-232 or RS-485 serial commands transmitted by a touch
screen system, PC, or other serial controller
ETHERNET
Remote contact closure for forced operation
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-81HD
away from moisture, excessive sunlight and dust
