3 Overview
The
VP-311DVI
is a high performance fail-safe 3x1 HDCP (high-bandwidth
digital content protection) compliant automatic switcher for DVI signals,
digital audio (S/PDIF) signals, and stereo audio signals.
The
VP-311DVI
switches any one of three DVI-D HDCP compliant sources
to a single display device, on DVI-I connectors with the corresponding:
•
Digital audio (S/PDIF) input signals switched to an S/PDIF output, on
RCA connectors
or
•
Unbalanced stereo audio input signals on 3.5mm mini jack connectors
switched to an unbalanced stereo audio output on a 3.5mm mini jack
connector, as well as to a balanced stereo audio output on a 5-pin terminal
block connector
The
VP-311DVI
can operate either in the manual mode or in the auto mode:
In the manual mode, the
VP-311DVI
acts as a regular switcher, switching the
input video and audio signals to the output via the three front panel INPUT
SELECT buttons.
In the auto mode, you can switch any input to the output via the three front
panel INPUT SELECT buttons, but once the selected video signal is lost, the
machine automatically switches to the highest priority input, according to the
input priority setup

The
VP-311DVI
is housed in a desktop-sized enclosure and is 12V DC fed.
. The
VP-311DVI
will switch back to the primary input
when a DVI signal is detected on that input.
Control the
VP-311DVI
using the front panel buttons, or remotely via:
•
RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
•
The Kramer infrared remote control transmitter
•
The ETHERNET
•
Remote control contact closure
3.1 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard (developed
by Intel), protects digital video and audio signals transmitted over DVI or
DVI connections between two HDCP-enabled devices to eliminate the
reproduction of copyrighted material. To protect copyright holders (such as
movie studios) from having their programs copied and shared, the HDCP
standard provides for the secure and encrypted transmission of digital signals.
