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

The Gefen VGA Extender SRN
The VGA Extender SRN allows users to extend video signals far beyond the A/V
rack. The VGAExtender SRN can be used to extend an analog VGAsignal 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.
Ifusinganon-VESAstandardresolution orif EDIDis needed,an EDIDstorage
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 VGAto
DVI adapters.
Use industry standard Category-5 (CAT-5) cable to operate the VGAExtender• 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.

The link light will stay on when a VGA connection is made with the source and the
sender unit. If the link light turns off verify that the VGAcable is connected properly
from the source to the sender unit and the display to the receiver unit. The receiver
end link light will stay on as long as a CAT-5e cable is connected between the send-
er and receiver unit
The power light will stay on as long as the power supply is connected to the sender

How to Connect the VGA Extender SRN
Connect the VGA Extender SR sender unit to the VGA output on the back of1. 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 VGA2. 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 VGAExtender SR4. 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 VGAto 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 flat 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 specifically engineered their products to work with the TIA/EIA-568-B
specification. Please adhere to the table below when field 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.
