INTRODUCTION

Congratulations on your purchase of the 2x Dual Link DVI KVM Extender Over
CAT-6. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
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 2x Dual Link DVI KVM Extender Over CAT-6a

The 2x Dual Link DVIKVM Extender over CAT-6a is a cost-effective solution that
allows the extension of keyboard, video and mouse to a remote workstation up
to 200 feet (60 meters away). This product is particularly useful because it is able
to extend dual link resolutions beyond the limitations of standard DVI cables.
Dual-link resolutions up to 3840 x 2400 are supported using two CAT-6a cables
for each display. USB 2.0 data rates up to 480 Mbps are supported in addition to
backward-compatibility with USB 1.1. The Receiver unit allows the connections
of up to four USB devices, providing access to printers, scanners, cameras,
external storage media, digital signage, and automated control systems.

How It Works

Place the 2x Dual link DVIKVM Extender over CAT-6a Sender unit next to the
DVI sources. Use the included DVI cables to connect the DVI sources to the
Sender unit. Use the supplied USB cable to connect the USB host (source)
device to the USB port on the Sender unit. Connect the Receiver unit to two
dual-link DVI displays using DVI cables. Connect up to four USB devices to
the Receiver unit. Use ve CAT-6a cables, each up to 200 feet (60 meters), to
connect the Sender to the Receiver unit. Connect the included locking power
supplies to the Sender and Receiver units and plug both power cords into
available electrical outlets.

DIP SWITCH CONFIGURATION

DIP Switch Location

On the bottom of both the Sender unit and Receiver unit is a bank four (4) DIP

switches.

The DIP switches on the Sender unit allow the management of EDID, ber optic
extenders, and HDCP.

Sender unit

DIP Switch 1 - EDID Management

• ON - Pass Through EDID

DDC and HPD are passed through. Both the connection status and the full
video capabilities of the monitor. All video features of the connected devices
are passed to the source device.

• OFF (default) - Local EDID

When Local EDID mode is used, the EDID will be assembled by copying all
video features of the connected output device.

The four DIP switches on the
bottom of the Sender unit.

NOTE: The DIP switches on the Receiver unit do not provide any
function and are reserved for future expansion.

11

DIP SWITCH CONFIGURATION

DIP Switch 2: +5V for Fiber Optic Extenders

• ON - Enable +5V

Enable +5V for DVI ber optic extenders.

• OFF (default) - Disable +5V

Disable +5V for DVI ber optic extenders.

DIP Switch 3: DVI Support*

DIP switch 3 is only functional when DIP switch 1 is set to OFF (Local EDID).

• ON - DVI Mode

If a DVI connection is used, set DIP 3 to the ON position. DVI is supported
by disabling HDCP pass-through.

• OFF (default) - HDCP Pass-Through

If HDMI is connected, set DIP 3 in the OFF position.

DIP Switch 4: Not used

• Reserved for future expansion.

IMPORTANT: After changing DIP switch 1 or DIP switch 3, the
Sender unit must be power-cycled for the changes to take effect.

ADJUSTING THE SIGNAL QUALITY

Adjusting the Signal Quality

The 2x Dual Link DVIKVM Extender Over CAT-6a Receiver unit has two trim pots
(trim potentiometers) to compensate for the extension distance and the quality/skew
variances that are found in different CAT-6a cabling brands. EQ 1 adjusts the output

signal for DVI Out 1 and EQ 2 adjusts the signal for DVI Out 2. If there is no output

video or if output video contains video artifacts and/or video noise such as snow,
use the steps below to adjust the trim pot.

1. Insert a small at-headed tool into each of the trim pots on the front panel of
the Receiver unit.

2. Each trim pot has 8 set positions. Turn the trim pot in a clockwise fashion

until it clicks to the next position. Continue adjusting the trim pot by trying
all 8 positions until the issue is resolved.

3. Carefully remove the adjustment tool.

Trim Pot Trim Pot

IMPORTANT: Any time a cable is changed-out or replaced, the trim
pots on the Receiver unit will need to be adjusted.
