2. Overview

2.1 Introduction

Normally, computers are designed to drive their VGA (Video Graphics Array)
output to only one nearby monitor. Often, however, circumstances call for VGA
output to be driven to one or several monitors far from the computer. That's
where our family of VGA Video Splitters comes in.
A typical application for one of these Splitters involves a PC simultaneously
sending VGA output to its own monitor, usually placed nearby, and to as many as
nine remote monitors, located around the room or in another room up to
250 feet (76.2 m) away. This makes your Splitter perfect for conference rooms,
classrooms, public information displays, show exhibits, and demonstrations. For
more about VGA Video Splitter applications, see Chapter 5.
If you need to hook up more monitors than one Splitter can accommodate, you
can "cascade" Splitters by attaching one or more secondary units to the
MONITOR ports of the primary unit. See Section 3.3.
These VGA Video Splitters come in compact, attractive desktop enclosures. They
are powered by an external power supply and draw no power from the sending
computer. Each Splitter can be located up to 6 feet (1.8 m) from this computer.
With bandwidths of 300 MHz, these VGA Video Splitters can handle resolutions
of VGA, SVGA (Super VGA), XGA (Extended Graphics Array), or XGA-2 as high as
1600 x 1280 pixels, at refresh rates as high as 75 Hz. They support a variety of
synchronization options, including H & V sync, composite sync, sync-on-green,
sync-on-RGB, and 75-ohm sync loads.
