Chapter 2: Overview
2. Overview
2.1 Introduction
The Compact Video Splitter (2-, 4-, or 8-port) broadcasts and boosts one VGA
signal source to 2, 4, or 8 VGA monitors. Use it for presentations, exhibits,
demonstrations, trade shows, monitor testing, or business meetings.
There’s no software or interface card to install. Simply connect the cables, power on
the splitter, and you’re ready to transmit one VGA image to multiple monitors with
excellent quality. A high-bandwidth circuit enables a high-resolution, 350-MHz VGA
signal to display on 2 or 4 monitors, or a 300-MHz signal to display on 8 monitors.
The maximum distance between the VGA input source and the output can be
up to 210 feet (64 m). (For distances longer than 10 feet [3 m], you must supply
the output cables.) The splitter works with VGA, SVGA, and multisync monitors to
provide crisp, clear VGA images. Cascade splitters for more VGA outputs. (Call Tech
Support for details.) If the VGA input is lost, the splitter automatically saves power.

Chapter 3: Installation
3. Installation
1. For the 2-port model (AC1056A-2), you’ll need two HD15 male-to-male output
cables (one of these cables is included). You’ll also need one input cable (includ-
ed).
For the 4-port model (AC1056A-4), you’ll need four output cables (three of these
cables are included) and one input cable (included).
For the 8-port model (AC1056A-8), you’ll need eight output cables (seven of
these cables are included) and one input cable (included).
Connect multiple monitors to the video splitter’s output connectors as shown in
Figure 3-1.
NOTE: If you want to use the Compact Video Splitter’s Display Data Channel (DDC)
feature, you must have a monitor on Port 1. If you have additional monitors
on other ports with higher resolutions, they will only support the resolution
of the monitor on Port 1.

2. You’ll also need to connect the Compact Video Splitter’s input connector to the
VGA source. Use an HD15 male-to-male cable (included) for this connection.
3. Connect the included power supply cord’s barrel connector to the barrel
connector receptacle on the Compact Video Splitter. Then plug the other end
of the power cord into an AC outlet.
4. Operation
Once the Compact Video Splitter is installed, it operates unattended. The splitter has
two front-panel LEDs that indicate its status at a glance.
• The Active LED lights when there is a VGA signal at the input port.
• The Power LED lights when the Compact Video Splitter is powered by the 5-VDC
power adapter.
