T
he Gefen 2x Dual Link DVI Extender over CAT-
6
The 2x Dual Link DVI Extender over CAT-6 extends any dual link DVI source,
to two displays up to 200 feet (60 meters) away. Dual-link resolutions up t
o
840 x 2400 are supported using four CAT-6 cables. Extending dual-link
esolutions over standard DVI cables have a limitation of 15 feet. Exceedin
g
this distance requires additional repeaters and/or boosters. The 2x Dual Lin
k
DVI Extender over CAT-6 provides an easy-to-install solution, using CAT-6
les.
How It Works
Place the 2x Dual Link DVI Extender over CAT6 Sender unit next to the source.
se the included DVI cables to connect the DVI source(s) to the Sender unit.
onnect the Receiver unit to the DVI displays using DVI cables. Connect
the Sender unit to the Receiver unit using four CAT-6 cables up to 200 feet
60 meters). Connect the included locking power supplies to the Sender and
eceiver units, then connect both power cables to available electrical outlets.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 2X DUAL LINK DVI EXTENDER OVER CAT-
6
• The 2x Dual Link DVI Extender over CAT-6 was designed for use with high
uality CAT-6a (augmented) cabling. This unit will either not perform to
pecifi cation or refuse to operate completely if cabling other than CAT-6a is
.
• When fi eld terminating CAT-6a cabling please adhere to the TIA/EIA-568-B
pecifi cation shown on page 12.
• The 2x Dual Link DVI Extender over CAT-6 has a maximum distance
ating based on the bandwidth (i.e. resolution and color) of the video being
transmitted. When used with high quality CAT-6a cabling, you can expect a
aximum extension range of 200 feet (60 meters) at 3840 x 2400 or 1080p
esolution. Lower quality cabling or older standards such as CAT-5 cables
will shorten the maximum achievable extension distance.
• For CAT-5e cables, the maximum distance is 150 feet at 1080p Full HD or

ADJUSTING THE SIGNAL QUALITY
Adjusting the Signal Qualit
y
The 2x Dual Link DVI Extender over CAT-6 Receiver unit has two trim pot (trim
otentiometers) to compensate for the extension distance and the quality/skew
variances that are
f
ound in different CA T-6a cabling brands. EQ1 adjusts the output
ignal for DVI 1 and EQ2 adjusts the output signal for DVI 2. If there is no output
video or if output video contains video artifacts and/or video noise such as snow
,
se the steps below to adjust the trim pot.
1. Insert a small fl at-headed tool into each of the trim pots on the front panel of
th
eiver u
nit.
2. Each trim pot has 8 set positions. Turn the trim pot in a clockwise fashion
ntil it clicks to the next position. Continue adjusting the trim pot by trying all
positions until the issue is resolved.
.
arefully remove the adjustment tool.
