INTRODUCTION

Congratulations on your purchase of the 4x1 DVI KVM Switcher. 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.

Gefen’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 4x1 DVI KVM Switcher

The rack-mountable Gefen 4x1 single link DVI KVM Switcher offers an

economical solution by eliminating the need to purchase many displays for each

computer in a studio or lab situation. A plug-and-play solution that supports both

Macintosh and IBM-PC computers, the 4x1 DVI KVM Switcher shares one DVI

display with up to four computers or other DVI video sources. A single USB 2.0

port, keyboard & mouse ports, and an analog audio jack are also switched. The

switcher saves space on your desktop by eliminating a crowded workspace full

of DVI monitors, keyboards & mice, and USB and audio cables. Switching of DVI

sources is easy and reliable.

How It Works

The DVI monitor is connected to the 4x1 DVI KVM Switcher’s output. Up to four

DVI video sources connect to the switcher’s DVI inputs using included high

quality DVI cables. The included power supply is connected to the switcher via

the locking power plug and then to a power outlet. The currently selected DVI

video signal appears on the shared monitor. DVI Video sources (and optionally

keyboards & mice, USB and audio cables) are selected/switched using the RMT-

4IR remote control, RS-232 control, or the input selector push button on the front

panel of the switcher.

CONNECTING & OPERATING THE 4X1 DVI KVM SWITCHER

How to Connect the 4x1 DVI KVM Switcher to your devices:

1. Connect your computers’ DVI, USB, and Audio sources to the 4x1 DVI KVM

Switcher inputs using the supplied cables.

2. Connect your USB and audio devices to the USB and audio outputs using the

supplied cables.

3. Connect your DVI-compliant display to the DVI output of the 4x1 DVI KVM

Switcher using a user-supplied DVI cable.

4. Connect the included 5V DC power supply to the Switcher by connecting its

5V DC power supply tip into the receptacle in the rear of the unit, then plug it

into the wall.

5. Turn on the DVI display or projector ﬁrst, then the DVI video sources/

computers.

Note: Computers must be turned on one at a time and the switcher must

be selected to the computer that is booting up. This is so that monitor

information (EDID) can be transmitted from the display to each computer.

After one computer completes the startup process, you can boot up the

second computer and repeat the process with the remaining computers.

How to Operate the 4x1 DVI KVM Switcher:

1. Use the RMT-4IR remote control to remotely switch between DVI video

sources.

2. Alternatively, use the front panel selector buttons.

OPERATION NOTES & TROUBLESHOOTING

USB

If your USB stops functioning correctly, you can manually re-intialize the

USB hub in the switch by pushing twice on the channel select button that

corresponds with the channel that the switcher is pointed at, on the front of

the unit. This will cause the channel selected LED to blink once letting you

know that the internal USB hub has been re-initialized. To have the USB

re-initialize automatically every time you switch, look under the 4x1 DVI

Switcher and locate the blank sticker. Peel it off to reveal a bank of four dip

switches. Find the dip switch labeled “4” and ﬂip it to the ON position. Now

every time you switch the hub will re-initialize itself.

Video

When turning on or rebooting your computers, the 4x1 DVI KVM 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. If you lose your picture when you switch between sources you will

need a DVI Detective.
