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.

The DDC cable (for each pair or extensions) does not need to be run if the •
source does not require HDCP or DDC. In this scenario, a single CAT-5,
CAT5e or CAT-6 cable for the video can be run. If DDC is still required while
HDCP is not, the use of an EDID storage device (part# EXT-DVI-EDIDN,
EXT-DVI-EDIDP) can be used to transmit DDC information back to the
source with this single cable solution.

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.

Power supply for the receiver should not be connected unless you are using •
the single CAT-5, CAT-5e or CAT-6 cable solution listed above.

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.•
