OPERATION NOTES
INTRODUCTION
Thank you for purchasing the DVI CAT5 4X Extender.
The DVI CAT5 4X Extender can extend 4 single link (1920 x 1200) DVI sources
to 4 displays up to 300ft away.
The 4x4 DVI CAT5 Distribution Amplier is the perfect solution for anyone who
needs to send multiple sources to multiple displays in remote locations at the
same time.
The DVI CAT5 4X Extender has 4 DVI single link inputs with 8 (2 per display)
RJ45 output ports. Each pair of CAT5e cables will extend out to a single receiver
with 2 RJ45 inputs and one DVI output port for your display. This will allow you
to extend 4 separate video signals to 4 remote locations.

READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE DVI CAT5 4X Extender
• The DVI CAT5 4X Extender and DVI CAT5 MSR units are housed in a metal
box for better RF shielding.
• Your CAT5e cables should not exceed 300 feet.
• If you do not need DDC or HDCP data you can use a single CAT5e 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 CAT5e cables
must be used between the sender and receiver units.
• If you are using a single CAT5e cable and the source requires EDID present,
you can use the Gefen DVI Detective to provide EDID information to your
source. The DVI Detective will not transmit HDCP.
• Shielded CAT5e or CAT6 with metal RJ-45 connectors is recommended to
protect from random video ashes caused by EMI.
• Power supply for the receiver should not be connected unless you are using
one CAT5e or going over a distance of 180ft.
• Extensions over 130ft. require you to manually EQ your signal (see page 5).
• Extensions under 130ft. use Auto EQ (which is on by default) (see page 5).
NOTE: The DVI CAT5 4X Extender is fully HDCP compliant

HOW TO USE THE EQ TRIM POT
The EQ trim pot is used extensions over 130 ft. By default, the DVI CAT5
MSR receivers come set to "Auto EQ" (with dip switch 1 ON). Underneath
the receiver is a bank of dip switches hidden by a blank sticker. If you ip dip
switch 1 OFF 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 to the ON position you can set the DVI CAT5 MSR to "Auto EQ". Auto EQ
works only when the sender is set to "NO BOOST" (see page 6). Auto EQ
works reliably up to 130ft. If you are using the DVI CAT5 MSR beyond any
distance of 130 ft. you will have to manually EQ your signal.
USING THE TRIMPOT
Have both of your CAT5e or CAT6 cables connected.
Start by having the source connected and playing with your display on.
Start with the trimpot turned all the way counter clockwise and slowly turn
the trim pot clockwise until the image stablilizes and displays no noise.

If you still do not get a picture or have video noise, set the sender's to medium
boost and try to re-EQ your signal. If that still does not work try the high boost
setting.

DIP SWITCH GUIDE
6
The EXT-DVI-CAT5-4X and EXT-DVI-CAT5MSR products both contain a set
of service switches (also called dip switches) located underneath each unit.
The EXT-DVI-CAT5-4X has 4 sets of DIP switches, one for each input, while
the EXT-DVI-CAT5MSR has a single bank of DIP switches. Peeling back the
silver sticker on the bottom of either unit will reveal the DIP switch bank. 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.)

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 7 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 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 CAT5e 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 of 15-20 feet. You can also make sure you have the correct boost setting
congured (refer to page 5).
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 CAT5e 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 and manually adjusting the equalization. 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.
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 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.
