4x4 Video Matrix Switch

1. Introduction

The Model VSM-404 is a 4 in x 4 out video switch matrix that provides
four independent outputs each capable of displaying any of the 4 inputs (or
blanked out). The inputs can be RGBHV (e.g. VGA from a PC), RGBS, or
RGsB with resolutions to 1600x1200 pixels, all inputs are terminated and
buffered using 250 MHz DC-coupled video amplifiers for a sharp and
perfect reproduction at each output. The VSM-404 outputs can drive
cables in excess of 150 feet.
An RS232 “Serial Port” is provided on the unit to control the selection for
the outputs. A Serial Keypad is supplied with each unit. The VSM-404
requires an external power supply for operation, which is also furnished
(The keypad does not require a separate power supply and is powered by
the base unit)
The VSM-404 employs HDD15 female connectors for all video inputs and
outputs (with standard SVGA pinout). All cable connections are located on
the rear of the unit. The front panel provides the on/off power switch and
individual indication of the channels selected for each output.

The Switch’s features include:

• With its large bandwidth, it can handle even very high resolutions

and refresh rates, up to 1600 x 1280 pixels at up to 85 Hz.

• It includes a serial keypad, so it’s ready to do manual switching

right out of the box

• Comes with a universal power supply

• It’s primarily designed to carry VGA/XGA video, but it ca n

handle separate horizontal and vertical sync, composite sync, and
sync on green, so with the right kinds of cables or adapters it can
accept all sorts of video from all sorts of devices.

• All of its input and output signals are buffered, so you’ll get the

sharpest possible images.

• It can drive video signals as far as 150 ft. end-to-end, so it’s ideal

for use in auditoriums, conference halls, and similar spaces.

• Its front-panel LEDs show you right away which video inputs are

going to which outputs.
