READ THESE NOTES BEFORE IN STALL ING
OR OPERATING THE DVI CAT-5 EXTREME EXTENDER
• The DVI CAT-5 Extreme is housed in a metal box for better RF shielding.
• Your CAT-5 cable should not exceed 200 feet.
• If you do not need DDC data you can use a single CAT-5 cable for the video only. The
DDC will not be connected.
• If the source requires EDID present, you can use the Gefen DVI Detective to provide
EDID information.

INTRODUCTION
The DVI CAT-5 Extreme sender unit sits next to your computer, DVD player or any settop box with a DVI output. The cable supplied with the DVI CAT -5 Extreme connects your
DVI source to the send unit. The DVI CAT-5 Extreme receiver unit sits next to your DVI
display - up to 150 feet away. The display plugs into the back of the DVI CAT-5 Extreme
receiver unit. Two CAT-5 cables connect the DVI CAT-5 Extreme-S and the DVI CAT-5
Extreme-R units to each other.

Plug the 5V power supply into the DVI CAT-5 Extreme sender and receiver unit
You should now have picture. If you do not see a picture, try unplugging and re-
plugging the DVI input on the DVI sender unit. Make sure your CAT-5 cables are not
crossed. Recycle the power on the unit.

DIP SWITCH USAGE GUIDE
5
Gefen CAT5 Extreme products (sender and receiver) both contain a pair of dip
switches located underneath the unit. These dip switches are used to select from
sets of confi gurations that will equalize the signal to best match the conditions in your
setup.
Receiver Confi guration Sender Confi guration 10m to 33m Cables
Dip #1 Dip #2 Dip #1 Dip #2
Off Off Off Off Very Good quality cable
On Off Off Off Good quality cable
Off On Off Off Medium cable
On On Off Off Bad cable
Dip #1 Dip #2 Dip #1 Dip #2 2m to 10m Cables
On Off On Off Very Good quality cable
On / Off Off On Off Good quality cable
Off On / Off Off Off Medium cable
On On / Off Off Off Bad cable
Adjustment Guidelines:
1) Dip #1 and Dip #2 on the receiver are Equalization Controllers
a) When both are OFF Equalization is zero => Good quality cables or Bad
quality short cables.
b) When both are ON Equalization is max => Bad quality long cables.
2) Dip #1 on the sender side should be ON when a short and good quality cable is
connected

Frequently Asked Questions
What kind of CAT-5e cable should I be using?
Solid core CAT-5e cable rated at 350 Mhz 568a or 568b is the minimum requirement.
CA T-6 cables are also a viable cable to use. Higher resolutions and transmission lengths
greater then 80 feet might require low skew cables for optimum performance.
I’m getting no video on the screens, what can I check?
First thing to check is make sure that the video CAT5 is linked to the other video CAT5
port and the same with the DDC ports. Test to make sure the units are working with short
CA T-5e cables 15-20 feet. Units shipped starting 12-2005 have the service switches inside
the unit enabled. Please refer to the Service Switch Usage Guide on page 5.
How can I fi x the fl ickering picture?
Flickering or a Blinking image is the result of a loss of sync between the display and the
source. Try lowering the resolution to see if that helps, if it does, the CAT -5 cables you are
using are unable to handle the bandwidth of the higher resolution and thus you are losing
sync. Try a shielded CAT-5e cable on the DDC to reduce interference.
Why is there a green or pink tint to my picture?
A tint of green or pink in the picture is a result of incorrect colorspace being transmitted.
This can be resolved by recycling power on your devices including the extender. If this
does not help, the DDC data containing the colorspace is not being transmitted correctly
due to loss in the CAT5 cable, try replacing the DDC cable.

CAT-5
Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair type cable
designed for high signal integrity . The actual standard defi nes specifi c electrical properties
of the wire, but it is most commonly known as being rated for its Ethernet capability of 100
Mbit/s. Its specifi c standard designation is EIA/TIA-568. Cat 5 cable typically has three
twists per inch of each twisted pair of 24 gauge copper wires within the cable.
CAT-5e
Similar to Cat 5 cable, but is enhanced to support speeds of up to 1000 megabits per
second.
DDC
Short form for Display Data Channel. It is a VESA standard for communication between
a monitor and a video adapter. Using DDC, a monitor can inform the video card about its
properties, such as maximum resolution and color depth. The video card can then use
this information to ensure that the user is presented with valid options for confi guring the
display.
DDWG
Digital Display Working Group DDWG are the creators of the DVI specifi cation.
DVI
Digital Visual Interface. Connection standard developed by Intel for connecting computers
to digital monitors such as fl at panels and DLP projectors. A consumer electronics version,
not necessarily compatible with the PC version, is used as a connection standard for HDTV
tuners and displays. Transmits an uncompressed digital signal to the display. The latter
version uses HDCP copy protection to prevent unauthorized copying.
HDCP
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV
signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent
unauthorized duplication of copy written material.
HDTV
High-Defi nition T elevision. The high-resolution subset of our DTV system. The A TSC defi nes
HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system,
accompanied by 5.1 channels of Dolby Digital audio. The CEA defi nes HDTV as an image
with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and
1920:1080i are typically accepted as high-defi nition scan rates.
VESA
Video Electronic Standards Association, a consortium of manufacturers formed to establish
and maintain industry wide standards for video cards and monitors. VESA was instrumental
in the introduction of the Super VGA and Extended VGA video graphics standards with
a refresh rate of 70 Hz, minimizing fl icker and helping to reduce user eyestrain and
fatigue.
