Congratulations on your purchase of the DVI over one CAT6 Extender. 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 DVI over one CAT6 Extender
The Gefen DVI over one CAT6 Extender will send a 1920x1200@60Hz DVI-D
signal over a single CAT-6a cable to distances of up to 200 feet (60m). Extension
of high resolution computer video can now be simplified with the use of only a
single CAT-6a cable. Previous solutions used 2 cables to accomplish this.
The DVI over one CAT6 extender’s pure digital transmission method insures
100% signal integrity over this single cable extension solution.
How It Works
The Gefen DVI over one CAT6 Extender system consists of two devices, a
sender and a receiver. The single-link DVI source (set-top box, DVD player, or
computer video card output) connects to the sender unit with the supplied 6-foot
DVI cable. The receiver unit connects to a DVI-compliant display. One CAT-
6a cable links the sender and receiver together at distances of up to 200 feet.
Power is applied to both the sender and receiver with the included 5V DC power
supplies. A perfect image is now displayed on the remote DVI display.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE DVI OVER ONE CAT6 EXTENDER
• The DVI over one CAT6 Extender was designed for use with high quality
CAT-6a (augmented) cabling. This unit will either not perform to specification
or refuse to operate completely if cabling other than CAT-6a is used.
• When field terminating CAT-6a cabling please adhere to the TIA/EIA-568-B
specification shown on page 12 for your convenience.
• The DVI over one CAT6 has a maximum distance rating based on the
bandwidth (i.e. resolution and color) of the video being transmitted. When
used with high quality CAT-6a cabling, you may expect a maximum
extension range of 200 feet (60 meters) at 1920x1200 or 1080p resolution at
up to a 60Hz refresh rate. Lower quality cabling or older standards such as
CAT5 cables will shorten the maximum achievable extension distance.
• For CAT5e cables, the maximum distance is 150ft at 1080p or 1920x1200.
• This product features HDCP pass-through.

How to Connect the DVI over one CAT6 Extender
1. Connect a DVI-D cable (one is supplied) between the DVI output on a
source device and the DVI input connector on the DVI over one CAT6
Extender sender unit.
2. Connect a single CAT6a cable between the sending and receiver units.
NOTE: When field-terminating CAT6a cabling please adhere to the TIA/EIA-
568-B specification. Please see page 12 for more information.
3. Connect a DVI-D cable (user-supplied) between the DVI input on a DVI-
compliant output device (i.e. computer display) and the DVI output on the
DVI over one CAT6 Extender receiver unit.
4. Connect the included 5V DC power supplies (two are included) between the
sender and receiver units and available power outlets.
5. Power up the DVI output device (i.e. DVI computer monitor) first and the DVI
source device (i.e. computer) last.

CONNECTING AND OPERATING THE
DVI OVER ONE CAT-6 EXTENDER
Adjusting the Signal Quality
The DVI over one CAT6 receiver unit has a equalization device called a Trim
Pot (trim potentiometer) to compensate for the extension distance and the quality/
skew variances that are found in different CAT6a cabling brands. If there is no output
video or if output video contains video artifacts and/or video noise such as snow,
please use the steps below to adjust the Trim Pot.
1. Insert a small flat-headed tool into the Trim Pot on the front panel of the
receiver unit.
2. The Trim Pot has 8 set positions. Turn the Trim Pot in a clockwise fashion
until it clicks into the next position. Continue adjusting the Trim Pot by trying
all 8 positions until the issue is resolved.
3. Carefully remove the adjustment tool.

DIP Switch Location
On the bottom of the Receiver Unit, there are four (4) DIP switches. Each DIP
switch performs a different function.
Before modifying DIP switch settings, disconnect the power from the Receiver
unit. After the DIP switches have been configured, reconnect the power.

DIP SWITCH CONFIGURATION
DIP Switch Settings
DIP 1 - EDID Management
• OFF - Local EDID
When Local EDID mode is used, the EDID will be assembled by copying
all video and audio features of the connected output device. Deep Color
support will be manually controlled using DIP switch 2 (see DIP 2 - Deep
Color, below).
• ON - Pass-through EDID
Allows all video and audio features of the connected devices to be passed
to the source device without control over Deep Color. By default, the unit is
shipped with DIP 1 in the ON position.
DIP 2 - Deep Color
• OFF - Disables Deep Color support
Disables Deep Color in the EDID. Deep Color management is only available
when Local EDID is being used (DIP 1 = ON).
• ON - Enables Deep Color support
Enables Deep Color support. In Pass-through EDID Mode, setting DIP 2 =
ON has no effect since all EDID information is passed through.

Gefen has specifically engineered products to work with the TIA/EIA-568-B
specification. Please follow the table below when field terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.
This product was designed for use with CAT-6a (augmented) cabling only. This
unit will either not perform to specification or refuse to operate completely if
cabling other than CAT-6a is used.
Each cable run must consist of a single undivided segment of CAT-6a cabling
from Sender to Receiver. Punch-down blocks or splices will not work.
