Is the power supply included?

Yes, the unit comes with a 5V DC power adapter. Note that both transmitter and receiver require power.

Can I use CAT5e cable instead of CAT6?

Yes, it works with both CAT5e and CAT6 cables, but CAT6 is recommended for optimal performance at longer distances.

How do I connect the DVI extender?

Connect the DVI source to the transmitter, run a CAT6 cable from transmitter to receiver, connect the receiver to the display, and plug in both power adapters.

What do the LED indicators mean?

The Power LED indicates unit is on, Link LED shows cable connection, and Signal LED lights when a valid DVI signal is detected.

Does the extender require any software or drivers?

No, it is plug-and-play and does not require any software or drivers.

Can I daisy-chain multiple extenders?

No, the EXT-2DVI-CAT6DL is designed for point-to-point connections only. For multiple displays, use a splitter.

What should I do if there is no video output?

Check all cable connections, ensure both units are powered, and verify that the source device is outputting a DVI signal. Try a different CAT6 cable if issues persist.

The 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 to 3840 x 2400 are supported using four CAT-6 cables. Extending dual-link resolutions over standard DVI cables have a limitation of 15 feet. Exceeding this distance requires additional repeaters and/or boosters. The 2x Dual Link DVI Extender over CAT-6 provides an easy-to-install solution, using CAT-6 cables.

How It Works

Place the 2x Dual Link DVI Extender over CAT6 Sender unit next to the source. Use the included DVI cables to connect the DVI source(s) to the Sender unit. Connect 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 Receiver units, then connect both power cables to available electrical outlets.

READ THESE NOTES BEFORE INSTALLING OR OPERATING THE 2X DUAL LINK DVI EXTENDER OVER CAT6

• The 2x Dual Link DVI Extender over CAT-6 was designed for use with high quality CAT-6a (augmented) cabling. This unit will either not perform to specification or refuse to operate completely if cabling other than CAT-6a is used.
• When field terminating CAT-6a cabling please adhere to the TIA/EIA-568-B specification shown on page 12.
• The 2x Dual Link DVI Extender over CAT-6 has a maximum distance rating 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 maximum extension range of 200 feet (60 meters) at 3840 x 2400 or 1080p resolution. Lower quality cabling or older standards such as CAT-5 cables will shorten the maximum achievable extension distance.
• For C AT-5e cables, the maximum distance is 150 feet at 1080p Full HD or 2560 × 1600 .

Features

• Extends Dual Link DVI on two Dual Link DVI displays up to 200 feet (60 meters) over tour CAT-6a cables
  • Supports Dual Link resolutions up to 3840 x 2400
  • EDID management for Local and Pass-through modes
• Locking Power Supplies
• Rack-mountable

Application

• Computer Extension over C AT-6 up to 3840 x 240

When connecting the CAT-6 cables, make sure that the connectors on the Sender unit are connected to the corresponding connectors on the Receiver unit (e.g. Link 1.1 --> Link 1.1, Link 1.2 --> Link 1.2, and so on).
   NOTE: When field-terminating CAT-6a cabling please adhere to the TIA/EIA-568-B specification. Please see page 12 for more information.
3. Connect two dual-link DVI cables from the Receiver unit to each of the two dual-link displays.

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, fiber optic extenders, and HDCP. The DIP switches on the Receiver unit do not provide any function and reserved for future expansion.

Sender unit

The four DIP switches on the 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 audio and 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 and audio features of the connected output device.

DIP Switch 2: +5V for Fiber Optic Extenders

- ON - Enable +5V

Enable +5V for DVI fiber optic extenders.

• OFF(default) - Disable +5V

Disable +5V tor DVI _fi 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

It 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

The 2x Dual Link DVI Extender over CAT-6 Receiver unit has two trim pot(trim potentiometers) to compensate for the extension distance and the quality/skew variances that are found in different CAT-6a cabling brands. EQ1 adjusts the output signal 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, use the steps below to adjust the trim pot.

1. Insert a small flat-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.
