READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE DVI CAT-5 MS EXTREME EXTENDER
• The DVI CAT-5 MS Extreme units are housed in a metal box for better RF
shielding.
• Your CAT-5 cable should not exceed 300 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 to your source but will not transmit HDCP.
• Shielded CAT6 with metal RJ-45 connectors is recommended to protect from
random ashes caused by EMI.
• Power supply for the receiver should not be connected unless you are using one
CAT5 or going over a distance of 200ft.
• Extensions over 130ft. require you to manually EQ your signal (see page 4).
• Extensions under 130ft. use Auto EQ (which is on by default) (see page 4).
• The extender is factory set to Auto EQ which will work for distances under 130 ft.
OPERATION NOTES

INTRODUCTION
The DVI CAT-5 MS Extreme sender unit sits next to your computer, DVD player or any
set-top box with a DVI output. The cable supplied with the DVI CAT-5 MS Extreme
connects your DVI source to the sender unit. The DVI CAT-5 MSR Extreme receiver unit
sits next to your DVI display - up to 300 feet away. The display plugs into the back of the
DVI CAT-5 MSR Extreme receiver unit. Two CAT-5 cables connect the DVI CAT-5
Extreme-S and the DVI CAT-5 MSR Extreme-R units to each other.

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.

HOW TO USE THE EQ TRIM POT
The EQ trim pot is used extensions over 130 ft. By default, the DVI Extreme comes
set to "Auto EQ" (with dip switch 1 OFF). Underneath the receiver is a bank of dip
switches, hidden by a blank sticker, and if you ip dip switch 1 ON you can turn off
the "Auto EQ" so that you can manually EQ your signal by using the EQ trim pot on
the receiver. If you ip dip switch number 1 back to the OFF position you can set
the DVI Extreme back to "Auto EQ". Auto EQ works best when the sender is set to
"NO BOOST" (see page 5). Auto EQ also works best up to 130 ft reliably. If you are
using the DVI CAT5 Extreme beyond any distance of 130 ft., then It is best if you
manually EQ your signal.
USING THE TRIMPOT
Have both of your CAT5 or CATs6 cables connected.
Start by having the source connected and playing with your display on.
Set the sender to medium boost.
Start with the trimpot all the way counter clockwise and slowly turn the trim pot
clockwise.

If you do not get a picture still or have noise, set the sender to high boost and try to
re-EQ your signal.

SERVICE SWITCH USAGE GUIDE
The sender unit of the Gefen CAT5 MS Extreme contain a set of service switches
(also called dip switches) located underneath the unit. Peeling back the silver
sticker on the bottom of the unit will reveal the service switch bay. These service
switches are used to boost 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 Boost OFF ON
Normal Boost (Default) OFF OFF
Strong Boost ON OFF
Receiver Dip Switch Settings
Setting Switch 1 Switch 2
Manual EQ ON OFF
Auto EQ 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 eliminate the possibility of cross talk and interference, cables must be
terminated with 568B scheduling. (See page 6 for details)
4) No Boost should be set when using Auto EQ.

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 shielded 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 congured (refer to page 5). If you are
getting no video or noise you can also try setting the DVI CAT5 Extreme to Auto EQ or
manually EQ your signal. (see page 4)
Occasionally the picture blanks out, how do I x 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. 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.
You can also try adjusting the service switches. Please refer to the service switch
guide on page 5 for the different combinations. Also eliminate any patch panels and
wall plates. Patch panels and wall plates are prone to EMI if they are not shielded
properly.
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 color space 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 color space 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 denes specic electrical
properties of the wire, but it is most commonly known as being rated for its Ethernet
capability of 100 Mbit/s. Its speci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
conguring the display.
DDWG
Digital Display Working Group DDWG are the creators of the HDMI specication.
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-Denition Television. The high-resolution subset of our DTV system. The ATSC
de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 de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-de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 icker and helping to reduce user
eyestrain and fatigue.
