READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE HDMI CAT-5 EXTREME EXTENDER
• The HDMI 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 or HDCP data you can use a single CAT-5 cable for the video
only. The DDC will not be connected. (For further information, see our Terminology
section on page 9.) If HDCP is required, both CAT-5 cables must be used between the
sender and receiver units.
• If the source requires EDID present, you can use the Gefen DVI Detective to provide
EDID information.
OPERATION NOTES

INTRODUCTION
The HDMI CAT-5 Extreme sender unit sits next to your computer, DVD player or any set-
top box with a HDMI output. The cable supplied with the HDMI CAT-5 Extreme connects
your HDMI source to the send unit. The HDMI CAT-5 Extreme receiver unit sits next to
your HDMI display - up to 200 feet away. The display plugs into the back of the HDMI
CAT-5 Extreme receiver unit. Two CAT-5 cables connect the HDMI CAT-5 Extreme-S and
the HDMI CAT-5 Extreme-R units to each other.
CONTENTS

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

SERVICE SWITCH USAGE GUIDE
5
The Senders and Receivers of the Gefen CAT5 Extreme products both contain a set of
service switches (also called dip switches) located underneath each unit. Peeling back
the silver sticker will reveal the service switch bay. These service switches are used
to boost and equalize the signal to best match the conditions in your setup. (*Note:
Adjustments should be done with sources and display on. Switches 3 and 4 are not
used.)

No EQ (Default) OFF OFF

Adjustment Guidelines:
1) Strong boost should not be used on stranded cables. Strong boosting will cause
pixels or no picture on these cables.
2) Using the wrong settings will not damage the units; it will either produce no
image or a noisy image.
3) To elminate the possibility of cross talk and interference, cables must be
terminated with 568B scheduling. (See page 6 for details)

Frequently Asked Questions
What kind of CAT-5e cable should I be using?
Solid core CAT-5e cable rated at 350 Mhz and terminated in 568a or 568b is the
minimum requirement. For resolutions greater than 1280x1024 or 1080i, Gefen
recommends solid CAT-6 cables.
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. Try removing the power supply from the receiver side,
if the power light turns off then you have your CAT-5 cables crossed. In some setups with
grounding issues you will not get a picture with the receiver powered. Test to make sure
the units are working with short CAT-5e cables 15-20 feet. You can also make sure you
have the correct boost setting configured (refer to page 5).
Occasionally the picture blanks out, how do I fix this?
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-6 cable on the video line to reduce interference.
You can also try adjusting the service switches. Usually this is caused by EMI and
a shielded CAT-6 with metal RJ-45 connectors with the drain wire soldered to the
connectors will resolve the issue. Please refer to the service switch guide on page 5 for
the different combinations.
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 defines specific electrical properties
of the wire, but it is most commonly known as being rated for its Ethernet capability of 100
Mbit/s. Its specific 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 configuring the
display.
DDWG
Digital Display Working Group DDWG are the creators of the HDMI specification.

audio/video source, such as a set-top box, DVD player, andA/V receiver and a compatible
digital audio and/or video monitor, such as a digital television (DTV).
HDCP
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV
signals over HDMI and HDMI connections and on D-Theater D-VHS recordings to prevent
unauthorized duplication of copy written material.
