INTRODUCTION

Congratulations on your purchase of the 4x1 DVI DL 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 DL Switcher

The rack-mountable Gefen 4x1 DVI DL Switcher offers an economical solution by

eliminating the need to purchase many displays for each DVI source in a studio

or lab situation. A plug-and-play solution, the 4x1 DVI DL Switcher shares one

dual-link display with up to four computers or other DVI video sources, saving

space on your desktop. The source computer is selected using the included IR

remote control or through RS-232 control.

How It Works

The DVI monitor is connected to the switcher’s output. Up to four DVI 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 computer’s video signal

appears on the shared monitor. Video sources 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.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE GEFEN 4X1 DVI DL SWITCHER

single-link resolution inputs and switch them, one at a time, to a DVI output

device such as a display/monitor or projector. Resolutions can be up to

3840x2400.

• The 4x1 DVI DL Switcher is housed in a metal box for better RF shielding.

• By default, the EDID of the attached display is copied to all the local inputs.

Make sure that the display is connected to the switcher before applying

power.

CONNECTING AND OPERATING THE 4X1 DVI DL SWITCHER

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

1. Connect user supplied DVI cables from the DVI sources into the 4x1 DVI

Switcher’s Inputs.

2. Connect the cable from your display (monitor or projector) into the DVI Out

of the 4x1 DVI DL Switcher.

3. Connect the 5V power supply, then plug it into the wall. Turn on the DVI

display or projector ﬁrst, then the video sources (computers). Turn on

the 4x1 DVI DL Switcher by screwing its 5V DC power supply tip into the

receptacle in the rear of the chassis.

Note: The Switcher retrieves device resolution and video timing capability

information called EDID from the display and feeds it to all connected input

sources. This mode of operation is called LOCAL EDID mode. It allows

a much faster setup time and improved operational stability since input

sources do not need to individually collect and store EDID on their own.

If some sources do not display correctly, you can individually conﬁgure each

input source and/or program custom EDIDs (such as standard compatible

resolutions) into the Switcher, or alternately set each input source to directly

read EDID from the display device (with the Local EDID Mode turned OFF).

These procedures are covered in detail on pages 10-11 along with EDID

concepts in general.
