CHAPTER 2: 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 away 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 accomodate,
you can “cascade” Splitters by attaching one or more secondary units to the
MONITOR ports of the primary unit. See Section 3.4 .
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) away
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.
