INSTRUCTION MANUAL

MODEL : AB-4140

4X4 VGA Matrix Switcher

VGA Matrix Switcher Series

INTRODUCTION

Congratulations on your purchase of one of the most innovative VGA(RGBHV) 4x4 matrix switching products on the market Today. The
AB-4140 is a true Matrix Routing Switcher for VGA(RGBHV) signals.

It has 4 individual VGA(RGBHV) inputs with 4 individual RGBHV outputs. Because it is a matrix router, any input may be routed to any
output; or the same input may be routed to all outputs or any combination. It completely eliminates the need to constantly move around
VGA video input and output cables.

The AB-4140 is useful for Matrix signals from VGA source devices (such as: Personal computer, Set Top Box, and Satellite Receivers,
etc.) To VGA destination devices (Such as LCD Monitors, VGA Monitors, Plasma LCD TV, VGA Projectors, etc.). Selection of inputs is
made via the front panel push buttons or an Infrared Remote Control unit or RS-232 control by a computer.

Package Includes:

(1) AB-4140 4x4 Matrix Switcher
(2) IR Remote Control
(3) Rack Mounts
(4) RS-232 driver CD (All Windows Operating Systems)
(5) Users Guide
(6) AC/DC Adapter: 12VDC, 100 ~ 230 VAC

AC/DC Adaptor Types : CE/UL/SAA/BS

To prevent damage to your television equipment, use only the supplied

AC Adaptor and make the power connections to your television

Safety Notice!

is acceptable.

Disconnect the cables from the this switcher or distributor inputs and connect them directly to an appropriate monitoring
device, if you do not see or hear a signal the problem may well be he signal source itself. Also check that the AC outlet you
have used to power the switcher or distributor is actually providing power as a wall switch often controls an AC outlet.
