INTRODUCTION
The HDMIEXTEND extends your HDTV display up to 200 feet away from your HDTV source using
two CAT-5 cables. It is equipped with HDMI™ (high definition multimedia interface) connectors and is
capable of supporting DVI (digital visual interface) equipment when used with a HDMI to DVI Adapter,
providing greater flexibility and options when integrating several home theater components.
HOW IT WORKS
The HDMIEXTEND transmitter unit sits next to your computer, set-top box or DVD player source.
Cables supplied with the HDMIEXTEND connect your DVI or HDMI™ source to the transmitter unit.
The HDMIEXTEND receiver unit sits next to your HDTV display - up to 200 feet away. The display
plugs into the back of the HDMIEXTEND.
The HDMIEXTEND system consists of:
(1) HDMIEXTEND transmitter
(1) HDMIEXTEND receiver
(1) 6 ft HDMI to HDMI Cable M-M
(2) HDMIEXTEND wall-mount adaptor plates
(2) 5VDC power supply

INSTRUCTIONS
1) Connect your display to the HDMIEXTEND receiver unit
2) Connect your source to the HDMIEXTEND transmitter unit
3) Connect your CAT-5 cables between the transmitter and the receiver
4) Plug the 5V power supply into the HDMIEXTEND transmitter and receiver unit
You should now have picture. If you do not see a picture, try unplugging and replugging the HDMI
input on the HDMI sender unit. Make sure your CAT-5 cables are not crossover type and have been
properly crimped and tested. Cycle the power on the unit.
* If problems persist try adjusting the Dip Switches by following the Dip Switch Usage Guide.

OPERATION NOTES
READ THESE NOTES BEFORE INSTALLING OR OPERATING THE HDMIEXTEND
•The HDMIEXTEND transmitter and receiver is housed in a metal box for better RF shielding.
•The 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 Technology Terminology
section) If HDCP is required, both CAT-5 cables must be used between the transmitter and
receiver units.
•CAT6 cable is suitable for high resolutions at 50 meters.
SERVICE SWITCH USAGE GUIDE
The transmitter and receiver of the HDMIEXTEND 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.)
Transmitter Dip Switch Settings
Setting Switch 1 Switch 2
No Boost OFF ON
Normal Boost (Default) OFF OFF
Strong Boost ON OFF

Receiver Dip Switch Settings
Setting Switch 1 Switch 2
No EQ (Default) OFF OFF
EQ Setting 2 ON OFF
EQ Setting 3 OFF ON
Maximum EQ ON ON
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 eliminate the possibility of cross talk and interference, cables must be terminated with 568B
scheduling.

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, Xantech Corporation 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.

TECHNOLOGY TERMINIATION
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.
HDMI
The High-Definition Multi-media Interface (HDMI) is an industry-supported, uncompressed, all-digital
audio/video interface. HDMI provides an interface between any compatible digital audio/video source,
such as a set-top box, DVD player, and A/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.
HDTV
High-Definition Television. The high-resolution subset of our DTV system. The ATSC defines
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 defines 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-definition 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 flicker and helping to reduce user eyestrain and fatigue.
