Congratulations on your purchase of the Gefen 2X1 DVIKVM DL Switch. 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. Geten'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 2X1 DVIKVM DL Switch

The 2X1 DVIKVM DL Switch allows effortless switching between two cross-platform dual link DVI computers using just one dual link DVI display and USB 2.0 keyboard and mouse. Audio, video and control signals are switched for each computer upon selection, providing an easy and effective method of accessing two computers from one workstation without the hassle of networking.

How It Works

Connect a dual link DVI display and USB 2.0 keyboard/mouse to the 2X1 DVIKVM DL Switch's outputs. Connect both computer's dual link DVI, USB and audio ports to the inputs on the Switcher using the supplied cables. From there, select the computer to control using the IR remote that comes with the Switcher. A contact closure remote control may also be used. The Switcher is compatible with both Macintosh and P C keyboards, mice and monitors.

PLEASE READ THESE NOTES BEFORE INSTALLING OR OPERATING THE 2X1 DVIKVM DL SWITCH

• When turning on or rebooting your computers, the DVI DL Switcher must be selected to the computer that is booting until the computer completes the boot cycle. This step can be eliminated using the Gefen DVI Detective, which stores the displays EDID.
• It you loose your picture when switch from source 1 to source 2 or vice-versa you will need a DVI Detective (Gefen part no. EXT-DVI-EDIDP).
• If you are experiencing USB dropouts try using the switcher just as a USB hub by only connecting the USB cables from your computers to the switcher. Connect your devices to the USB out portion of the switcher and connect your display to your computer directly. Start your computer up and try switching. If your USB devices do come up normally then you will need a DVI Detective to negotiate the video/USB signals for faster switching. If they do not come up normally, contact Gafen Technical Support for assistance.
