READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE DVI CAT-5 EXTENDER
• The DVI CAT-5 Extender is housed in a metal box for better RF shielding.
• Your CAT-5 cable should not exceed 150 feet.
• If you don't need DDC data you can use a single CAT-5 cable for the video only. The
DDC will not be connected. An additional 5 VDC power supply will be needed for the
receiver side.
• If the source requires EDID present, you can use the Gefen DVI Detective to provide
EDID information. This will also provide an additional 5v power supply for the receiver
side.
* CAT6 cable is suitable for high resolutions at 50 meters.

display - up to 150 feet away. The display plugs into the back of the DVI CAT-5 Extender
receiver unit. Two CAT-5 cables connect the DVI CAT-5 Extender-S and the DVI CAT-5
Extender-R units to each other.

DIP SWITCH USAGE GUIDE

Gefen CAT5 Extenders (sender and receiver) both contain a pair of dip switches
located on the board. These dip switches are used to select from a set of
configurations that will equalize the signal to best match the conditions in your setup.
How to open the DVI CAT5 Extender:
1. Unscrew the four screws underneath the unit.
2. Unscrew the 2 hex nuts beside the DVI connector.
3. Slide the top plate off the base to expose the circuit board.
4. The dip switches are located directly on the circuit board.
Sender Dip Switches
Option No. Switch 1 Position Switch 2 Position Description
1 0 (OFF) 0 (OFF) Medium Boost
(Default)
2 1 (ON) 0 (OFF) Strong Boost
Receiver Dip Switches
Option No. Switch 1 Position Switch 2 Position Description
1 0 (OFF) 0 (OFF) EQ 0
(Default)
2 1 (ON) 0 (OFF) EQ 1
3 0 (OFF) 1 (ON) EQ 2
4 1 (ON) 1 (ON) EQ 3
Adjustment Guidelines:
1) Higher EQ level is used to equalize poor/low quality CAT-5e cables
2) Stronger boost is used to drive signals through longer cables
3) It is an optimal balance of Boost and EQ that will result in the best possible
picture.
