4 VS-311H - Overview
3 Overview
The VS-311H is a high-performance 3x1 HDCP- compatible automatic switcher for
HDMI signals, digital audio (S/PDIF) signals and stereo audio signals.
The VS-311H switches any one of three HDMI, HDCP compliant sources to a
single display device, on HDMI connectors with the corresponding:

Digital audio (S/PDIF) input signals switched to an S/PDIF output, on RCA
connectors and/or

Unbalanced stereo audio input signals on 3.5 mini-jack connectors switched
to an unbalanced stereo audio output on a 3.5 mini-jack connector, as well
as to a balanced stereo audio output on a 5-pin terminal block connector
The VS-311H can operate either in the manual mode or in the auto mode.
In the manual mode, the VS-311H 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 VS-311H switches back to the primary input when an HDMI signal is
detected on that input.
When selecting an INPUT SELECT button, via the manual or auto mode, that
button lights. Pressing an illuminated button deselects that input and that button no
longer lights.
The VS-311H is housed in a desktop-sized enclosure and is 12V DC fed.
Control the VS-311H 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
