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 (45 meters). 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
(45 meters) 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.

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 (CAT-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.

CONNECTING THE VGA EXTENDER SRN
How to Connect the VGA Extender SRN
1. Connect the VGA Extender SRN sender unit to the VGA output on the back
of your computer. The supplied six foot M-F VGA cable connects the CPU
and sender unit together.
2. Connect the VGA Extender SRN receiver unit to your monitor with the VGA
cable that is attached to your monitor.
3. Connect CAT5 cable between the VGA Extender SRN sender and receiver.
4. Plug the 5-Volt power supply into the sender unit. The VGA Extender SRN
receiver unit will draw power from the sender.
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 non-VESA-standard resolutions or if EDID
is needed, an EDID storage and relay device is needed. Gefen
recommends using the DVI Detective (Gefen Part No. EXT-DVI-EDID,
EXT-DVI-EDIDN, or EXT-DVI-EDIDP) with two VGA to DVI adapters.

OPERATING THE VGA EXTENDER SRN
Adjusting the Signal Quality
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 skew 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, or if there is no output video or the image contains video artifacts such as
video noise / snow, use the steps below to adjust the Trim Pot.
1. Insert a small at head device, such as a screw driver into either the bright-
ness or focus trim pot hole.
2. Turn the trim pot in millimeter increments in either a clockwise or counter-
clockwise direction until the desired brightness and focus are reached.
3. Remove the adjustment device from the trim pot hole.
