Congratulations on your purchase of the VGA Extender SRN. Your complete
satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.

The Gefen VGA Extender SRN

The VGA Extender SRN allows users to extend video signals far beyond the A/V
rack. The VGA Extender SRN can be used to extend an analog VGA signal to
cover distances up to 150 feet. Industry standard Category 5e (CAT-5e) cable is
used for the extension.

How It Works

The VGA extender SRN sender unit connects to your computer using the
supplied VGA cable. The SRN receiver connects to your monitor - up to 150
feet away. One CAT-5 cable connects the sender and the receiver to each other,
extending your video. The video transmitter and receiver boxes are small and
unobtrusive, allowing installation in small spaces.

INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE VGA EXTENDER SRN

Display information (EDID) is not sent back to the source. Standard VESA •
resolutions should be output by most computers without the need of an EDID.
If using a non-VESA standard resolution or if EDID is needed, an EDID storage
and relay device is necessary . Gefen recommends the use of a DVI Detective
(part# EXT-DVI-EDID, EXT-DVI-EDIDN, or EXT-DVI-EDIDP) with two VGA to
DVI adapters.

Use industry standard Category-5 (CA T -5) cable to operate the VGA Extender •
SRN system. CAT-5e cable is preferred.

Please connect all the cables between the computer and the VGA Extender •
SRN before powering up the VGA Extender SRN unit.

The VGA Extender SRN units are housed in a metal box for better RF •
shielding.

How to Connect the VGA Extender SRN

Connect the VGA Extender SR sender unit to the VGA output on the back of 1.
your computer. The supplied six foot M-F VGA cable connects the CPU and
sender unit together.

Connect the VGA Extender SR receiver unit to your monitor with the VGA 2.
cable that is attached to your monitor.

Connect the CAT5 cable between the VGA Extender SR sender and receiv-3.
er’s CAT5 input.

Plug the 5 volt power supply into the sender unit. The VGA Extender SR 4.
receiver will draw power from the sender.

NOTE: Display information (EDID) is not sent back to the source. Standard VESA
resolutions should be output by most computers without the need of an EDID.
If using a non-VESA standard resolution or if EDID is needed, an EDID storage
and relay device is necessary. Gefen recommends the use of a DVI Detective
(part# EXT-DVI-EDID, EXT-DVI-EDIDN, or EXT-DVI-EDIDP) with two VGA to DVI
adapters.

BRIGHTNESS AND FOCUS TRIM POTS

The brightness and focus adjustments are found on the receiver unit and will help
compensate for issues that can be introduced by outside interference and cable
variances. If the outgoing image is too dark or too bright, the brightness trim pot
can be tuned to help brighten the image. If there is a ghosting or blurring effect
on the image, the focus trim pot can be used to eliminate these artifacts. Insert a
small fl at head device, such as a screw driver into either the brightness or focus
trim pot hole. Turn the trim pot in millimeter increments in either a clockwise or
counterclockwise direction. Once the desired brightness and focus are reached,
simply remove the adjustment device from the trim pot hole.

Gefen has specifi cally engineered their products to work with the TIA/EIA-568-B
specifi cation. Please adhere to the table below when fi eld terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.

CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types.
Gefen recommends using solid core cabling. CAT-6 cable is also recommended
for best results.

Each cable run must be one continuous run from one end to the other. No splices
or use of punch down blocks.
