8x2 Video Matrix Switch

1. Introduction

The Model VSM-802B 8 in x 2 out Video Matrix Switch is an ideal tool
for sharing and/or switching between the output of as many as eight video
sources (such as PCs), in order to display or capture that output at two
video destinations (such as monitors). Once you attach all your devices,
you can hook the Switch to the included keypads for full switching control.

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 two serial keypads, so it’s ready to do manual

switching almost right out of the box (you do have to attach the
keypad to the Switch first).

• Because it has a universal power supply, you can plug it in almost

anywhere if you have the right input cord. (And it’s small and
light enough to take almost anywhere!)

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

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 300 ft. (90 m) 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.

• To top it off, it can be operated by pressing a single keypad

button, so anybody can use it without having to be extensively
trained.

The Switch comes with:

• (2) 10-button keypads

• (2) 6-ft. (1.8-m) DB9 male to DB9 female keypad cables

• Power supply
