faction is very important to us.

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 LR
The VGA Extender allows users to extend video signals beyond the A/V rack.
The VGA Extender Series can be used to extend an analog signal to cover dis-
tances up to 330 feet. Industry standard Category 5e (CAT-5e) cable is used for
the extension.
How It Works
The VGA Extender LR sender unit connects to your source using the supplied
cable. The receiver unit connects to your display - up to 330 feet away. One
CAT-5 cable connects the sender and the receiver to each other, extending your
video flawlessly.
Note: This is a new VGAExtender that goes double the distance of the previous
version, and also has a trimpot for fine video adjustment.
INTRODUCTION
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE VGA EXTENDER LR
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 LR system. CAT-5e cable is preferred.
Please connect all the cables between the computer and the VGA Extender• LR before powering up the VGA Extender LR unit.
The VGA Extender LR units are housed in a metal box for better RF• shielding.

How to Connect the VGA Extender LR
Connect the VGA Extender LR sender unit to the VGA output on the back of1. your computer. The six foot M-F VGA cable connects the CPU and sender
unit together.
Connect the VGA Extender LR receiver unit to your monitor with the VGA2. cable that is attached to your monitor.
Connect the CAT-5e cable between the VGA Extender LR sender and3. receiver’s CAT5 input.
Plug the 5V DC power supply into the sender unit. The VGAExtender LR4. receiver will draw power from the sender.
BRIGHTNESS AND FOCUS TRIM POTS
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
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 small screw
driver into the focus Trim Pot hole. Turn the Trim Pot in millimeter increments in
either a clockwise or counterclockwise direction. Once the desired focus setting
has been 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.
