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.

OPERATION NOTES
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 SR •
system. CAT-5e cable is preferred
Please connect all the cables between the computer and the VGA Extender SR •
before powering up the VGA Extender SR unit
The VGA Extender SR 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 VGA cable 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 sender and receiver unit
The power light will stay on as long as the power supply is connected to the sender
unit.

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.
