Congratulations on your purchase of the DVI CAT5 4X Extender. Your complete
satisfaction is very important to us.

Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.
The Gefen DVI CAT5 4X Extender
The DVI CAT5 4X Extender is the perfect solution for anyone who needs to send
multiple (up to four) DVI video sources to multiple (up to four) DVI displays in
remote locations at the same time.
The DVI CAT5 4X Extender has 4 DVI video inputs. The DVI sources are sent to
up to four DVI CAT5 MS receivers via industry standard CAT-5, CAT-5e or CAT-6
cables. Distances of up to 300 feet for 1080i video, and 150 feet for 1080p video
are possible. Signal auto-equalization is set by default and will provide optimal
image reproduction for cable runs of 130 feet or less. Manual equalization is
available for cable runs at greater distances.
How It Works
Connect your DVI video sources to the DVI CAT5 4X Extender’s inputs using the
supplied DVI cables. Run two CAT-5, CAT-5e or CAT-6 network cables from the
DVI CAT5 4X Extender to each of the DVI CAT5 MS Receivers. Lastly, connect
up to four DVI displays to the DVI CAT5 MS receivers at the remote locations.
INTRODUCTION
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.
• The maximum cable extension is 300 feet (91 meters) for video resolutions
of 1080i and below.
• The maximum cable extension is 150 feet (45 meters) for video resolutions
of 1080p.
• If EMI is present anywhere near the RJ-45 video cable runs, it may
be necessary to use shielded RJ-45 cable. This is to prevent possible
interference from degrading the video signal. Using shielded cable, however,
will reduce the maximum distance that the RJ-45 cable can be run.
• Extensions under 130 feet can use Auto EQ (which is on by default).
Extensions over 130 feet will require you to manually EQ your signal (see
page 5).
• Each cable run must be one continuous run from one end to the other. No
splices or use of punch down blocks.
• High quality CAT-6 cabling should be used for maximum performance.
• Do not use stranded or low/no skew cabling. Solid core cabling should be
used for maximum performance.
• HDCP Compliant.

How to Connect the DVI CAT5 4X Extender
1. Connect your sources (up to four) to the DVI CAT5 4X Extender unit’s DVI
inputs using the supplied DVI cables.
2. Connect your displays (up to four) to the DVI CAT5 MSR receiver unit’s
DVI outputs using user supplied DVI cables.
3. Connect both CAT-5, CAT-5e or CAT-6 cables (DDC and Video) between
the DVI CAT5 4X Extender and each DVI CAT5 MSR receiver.
NOTE: If field terminating network cable, please adhere to the TIA/EIA-568-B
standard. Please see page 9 for more information.
4. Connect the 24V DC power supply into the DVI CAT5 4X Extender sender.
5. Connect the 5V DC power supplies into each of the DVI CAT5 4X receivers.
6. Power on the displays.
7. Power on the sources.
NOTE: If an image is not being shown on the display, please check all cabling for
proper connections and follow the steps outlined below and in the next section.
DVI CAT5 4X EXTENDER CONFIGURATION
The DVI CAT5 4X Extender and DVI CAT5 MSR receivers have built-in auto
equalization that will automatically tune out any unwanted video noise. This
feature is reliable with premium cable runs up to a maximum of 130 feet. It may
be necessary to disable this feature if there is either no video being displayed on
initial start-up, there is video noise in the image, or the cable run exceeds 130
feet. First, verify that all the proper connections have been made and that all
devices are powered on before attempting to disable auto equalization. Please
follow the section on the next page to manually equalize the video signal.
CONNECTING AND OPERATING THE DVI CAT5 4X EXTENDER

MANUAL EQUALIZATION PROCEDURE
The DVI CAT5 4X Extender and DVI CAT5 MSR receiver units both have sets of
dip switches located on the underside of their casings. There is a piece of silver
metallic tape that must be removed to expose these dip switches. The DVI CAT5
4X Extender unit carries 4 banks of 4 dip switches. Each DVI CAT5 MSR receiver
carries one bank of 4 dip switches. Dip switches 1 and 2 on both the sending and
receiving units are used in this procedure. Dip switches 3 and 4 are not used. By
default, dip switch 2 on each bank of the DVI CAT5 4X Extender should be in the
ON position, and all dip switches on each DVI CAT5 MSR receiving unit should
be in the OFF position (Auto EQ On). To turn off auto equalization, turn dip switch
1 on the receiving units to the ON position (Auto EQ off). With these settings,
please follow the steps below to equalize the picture.
1. Insert a small flat head tool into the trim pot on the receiver unit.
2. Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force
the trim pot beyond this point. Doing so may render the trim pot useless.
3. Slowly turn the trim pot counter-clockwise in millimeter increments until the
image stabilizes and all video noise disappears.
4. Carefully remove the adjustment tool.
NOTE: If your cable run is beyond 130 feet, or the steps above do not produce
any video, it may be necessary to increase the boost from the sending unit. Use
the chart below to increase the senders to medium boost by changing the DVI
CAT5 4X Extender’s dip switches. Once a new boost setting is set, repeat steps
1 through 4 from above. If this still does not produce and image, increase the
boost to high and repeat the EQ process.
