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.
2. Introduction

VGA VIDEO SPLITTERS
3.1 The Complete Package
You should have received all of these things with your Splitter order:
• (1) VGA Video Splitter of the appropriate model
• (1) External transformer (power supply)
• (1) 6-ft (1.8-m) DB15HD-male-to-DB15HD-male video cable for
connecting the computer’s VGA output to the VGA Video Splitter
• (1) Copy of this manual
If any of these items are missing, call your supplier right away. If any of these
items are damaged, call your supplier and the shipping carrier immediately.
3.2 The Procedure
Follow these steps to install the VGA Video Splitter:
1. Place the VGA Video Splitter within 6 feet (1.8 m) of the computer.
2. Run the included video cable from the computer’s VGA output to the
connector marked VGA IN on the rear of the Splitter.
3. Connect your primary monitor (the one that was previously attached
directly to the computer) to the connector marked MONITOR 1 on
the rear of the Splitter.
4. Connect the additional monitor(s) to the remaining MONITOR
connector(s) on the rear of the Splitter. You can use VGA extension
cables to extend the distance you can run to as much as 250 feet
(76.2 m); see Section 3.3.
5. Plug the output cord of the included power supply into the jack marked
POWER on the rear of the Splitter.
6. Plug the power supply into an AC wall outlet. The Splitter’s front-panel
LED should glow red to show that the unit is properly powered.
3. Installation

CHAPTER 3: Installation
7. The four-position DIP switch marked MONITOR TYPE on the front
panel of the VGA Video Splitter tells the VGA adapter in your computer
what type of monitors you have connected when the computer boots up.
For a standard application in which your remote monitor(s) are pretty
much interchangeable with your primary monitor (the one on
MONITOR 1), move all four switch positions to the “UP” setting; this
will cause the Splitter to pass the “ID bits” from the primary monitor
through to the VGA adapter. Moving all the positions to UP will not
work for applications in which:
• there is no monitor on MONITOR 1;
• the primary monitor is connected to MONITOR 1 with a VGA
extension cable that doesn’t carry the ID-bit leads;
• the primary monitor uses higher-grade video than one or more of the
remote monitors (for example, color VGA vs. monochrome VGA or
high-resolution XGA-2 vs. low-resolution VGA).
In these situations, set the MONITOR TYPE switch this way:
DIP Switch Positions Monitor Type
1234
DOWN UP DOWN UP Color VGA and XGA
DOWN DOWN UP UP Monochrome VGA
UP UP DOWN UP 8514/A
NOTE
If your monitors don’t belong to any of these three types, you must set
all four MONITOR TYPE switch positions UP and connect a
representative monitor to MONITOR 1 with cable that carries the
monitor’s ID-bit leads. If you don’t have such a cable, call your supplier
for a quote on a cable that carries all ID-bit leads.
8. Turn on the computer and the monitors. The monitors should now
display the computer’s output.
This completes the VGA Video Splitter installation. Once installed, the
Splitter shouldn’t require any adjustments; you can keep it out of sight.
It should now be ready for continuous operation.
