INTRODUCTION

Congratulations on your purchase of the 8x1 DVI 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 8x1 DVI Switcher

The rack-mountable Gefen 8x1 single-link DVI 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 8x1 DVI Switcher shares

one DVI display with up to eight 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 eight 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-8IR 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 8X1 DVI SWITCHER

• The 8x1 DVI Switcher will take any of up to eight (8) DVI 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 1920x1200.

• The 8x1 DVI Switcher is housed in a metal box for better RF shielding.

• Computers must be turned on one at a time and during this process the 8x1

DVI Switcher must be selected to the computer that is currently booting up.

This is so that monitor information (EDID) can be transmitted properly from

the display to each computer. Please see page 6 for further information.

PANEL DESCRIPTIONS

1 External IR Port

For connection of external IR extension device such as the Gefen IR Extender

(part # EXT-RMT-EXTIR).

2 IR Receiver

Receives IR signal from the handheld Infrared remote control unit included with

the product.

3 DVI Signal Status LEDs 1-8

Provide visual conﬁrmation of the currently selected DVI input signal out of the

eight DVI input ports.

4 Power Indicator LED

Indicates when the 8x1 DVI Switcher is receiving 5V DC power from its included

AC power supply.

5 5V Locking Power Receptacle

Supplies power to the 8x1 DVI Switcher from the included external 5V DC

power supply. The 5V power supply has a locking power tip which screws into

this receptacle.

6 DVI Input Ports 1-8

DVI video sources one through eight attach to the 8x1 DVI Switcher.

7 DVI Output Port

This DVI output port is connected to the display device (Monitor, Projector).

8 RS-232 Serial Communications Interface

Provided for external control of the 8x1 DVI Switcher.

CONNECTING AND OPERATING THE 8X1 DVI SWITCHER

How to Connect the 8x1 DVI Switcher to your devices:

1. Connect the supplied DVI cables from the DVI sources into the 8x1 DVI

Switcher’s Inputs.

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

of the 8x1 DVI Switcher.

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

DVI display or projector ﬁrst, then the video sources. Turn on the 8x1 DVI

Switcher by screwing its 5V DC power supply tip into the receptacle in the

rear of the chassis.

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

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

monitor information (EDID) is correctly 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.

This can be avoided with the use of the LOCAL EDID mode (page 11)

that will constantly supply each computer with an EDID. In this scenario, a

stored EDID, or user uploaded EDID, is supplied to each input for use by

the connected source device. Then, each computer can boot up in any order

and at anytime, regardless of which computer the switch is selected to.

How to Operate the 8x1 DVI Switcher:

4. Use the RMT-8IR remote control to remotely switch between DVI video

sources.

5. Alternatively, use a RS-232 control system such as a PC with

communications software (for example, Microsoft’s Hyperterminaltm) or an

automated control system such as Crestron.tm
