READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE DVI RS-232 EXTENDER
• The DVI RS-232 Extender is housed in a metal box for better RF shielding.
* In order to extend the full 150 feet you need a high quality CAT5e cable.
* We suggest a Belden Datatwist 1585Aor 1700 series cable or similar.
* CAT6 cable is suitable for high resolutions at 150 feet.
* If using a ADC-DVI Adapter, the "5V to cable" jumper by the input connector on the
sender unit needs to be enabled.
• If the source requires EDID present, you can use the Gefen DVI Detective to provide
EDID information.

DIP SWITCH USAGE GUIDE
6
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 RS-232 Extender:
1. Unscrew the four screws underneath the unit.
2. Unscrew the four hex nuts beside the RS-232 and DVI connectors.
3. Slide the top plate off the base to expose the circuit board.
4. The dip switches are located directly on the circuit board.
