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.
