COMPACT VIDEO SPLITTERS
2. Overview
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 splitter’s 2, 4, or 8 output connections attach to one
input, one local output, and 1, 3, or 7 remote outputs.
Cables for the input and remote outputs are included;
you must supply the cable for the local output.
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
multi-sync monitors to provide crisp, clear VGA images.

CHAPTER 2: Overview
Cascade splitters for more VGA outputs. (Call Tech
Support for details.) If the VGA input is lost, the splitter
automatically saves power.

HD15 male-to-male output cables (one of these
cables is included) to connect each video splitter’s
output connector to each computer’s VGA output
connector. You’ll also need one input cable
(included).
For the 4-port model (AC1056-4), you’ll need four
output cables (three of these cables are included)
and one input cable (included).
For the 8-port model (AC1056-8), 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.

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
