SERVICE SWITCH USAGE GUIDE The Sender and Receiver of the Gefen DVI Audio Extender both contain a set of service switches (also called dip switches) located underneath each unit. Peeling back the silver sticker will reveal the service switch bay. These service switches are used to boost and equalize the signal to best match the conditions in your setup.

TROUBLESHOOTING Frequently Asked Questions What kind of CAT-5e cable should I be using? Solid core CAT-5e cable rated at 350 Mhz and terminated in 568a or 568b is the minimum requirement. For resolutions greater than 1280x1024 or 1080i, Gefen recommends solid CAT-6 cables. I’m getting no video on the screens, what can I check? First thing to check is make sure that the video CAT5 is linked to the other video CAT5 port and the same with the DDC ports.
TERMINOLOGY CAT-5 Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair type cable designed for high signal integrity. The actual standard defines specific electrical properties of the wire, but it is most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Its specific standard designation is EIA/TIA-568. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cable.
