Description
The Model VS-2X2 is a versatile, compact, high performance, solid-state, 2 input x 2 output, VGA video switch
that can operate at resolutions of up to 1600x1200.
The unit can be thought of as a 2 input x 1 output video switch followed by a 1 input x 2 output video splitter
built in one convenient box. It allows two monitors to be switched between two video sources. The unit is
housed in a small RFI shielded enclosure and is supplied with an AC power adapter, a push-button remote
switch control cable, and a Serial (RS-232) control cable for connecting to a PC or other serial control device.
The device terminates both video input signals and buffers the output in order to protect signal integrity. The
Model VS-2X2 can drive video cables to 150 feet or more (depending on cable quality and resolution setting).
The input and output connectors are all HD15 Female (standard VGA style).
Features
• Allows two monitors to be switched between two video sources
• Can be controlled manually, via Serial port, or from TTL level (or contact closure)
• Select input 1, input 2, or blank the output
• Auto mode automatically scans and selects the input with active video (Inputs can also be
prioritized)
• Infinite switching cycle life
• Can drive long cables
• Terminates both video input signals and buffers the output to protect signal integrity
• Includes push-button and serial cables for control
Setup
Your package should include two control cables, a power adapter, and the Video Switch unit itself. Please
take inventory of all items received and ensure that you have the above items.
Connect INPUT 1 and INPUT 2 of the switch to your video sources such as computer or notebook PC. You will
require a cable for each connection. It is highly recommended that you use multi-coaxial high-resolution VGA
cables for this purpose. The cables would generally be male-to-male. Hall Research can provide cables from 3
feet to 100 feet or more; please contact us for pricing information.
Connect the display devices such as a monitor (or a video projector) to the outputs of the Switch. You can
connect one or two monitors to the unit. Both will show the selected input.
Set the dip switches according to the mode of operation that best suits your application.
Connect the supplied AC power adapter to the Splitter, and plug-in the push-button switch cord.
Plug-and-Play
DDC (Direct Data Channel) is a standard by which a compatible monitor sends its identification and other
parameters to a PnP operating system such as Windows 98 etc. The VS-2X2 does not switch the PNP signal
lines to the PC.
This means that, in some instances, you may have to select a new monitor or video settings on your PC. Also
notice that most Notebook PC’s have a special function key to activate the external video output connector.
