INTRODUCTION
Congratulations on your purchase of the 8x1 DVI DL/SL 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 DL/SL Switcher
The rack-mountable Gefen 8x1 single-link/dual-link DVI 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, the 8x1 DVI DL/
SL Switcher shares one dual-link 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.

8X1 DVI DL/SL REMOTE INSTALLATION
To use the RMT-8IR remote, remove the battery cover on the back of the remote to
reveal the battery compartment. Insert the included battery into the open battery slot.
The positive (+) side should be facing up. Ensure that both DIP (Dual Inline Package)
switches are in the OFF position. Replace the battery cover. The remote ships with 2
batteries. One battery is needed for operation and the other battery is complimentary.

RMT-8IR REMOTE AND 8X1 SWITCHER CONFIGURATION
How to Resolve IR Code Conflicts
In the event that IR commands from other remote controls conflict with the
supplied RMT-8IR remote control, changing the remote channel will alleviate this
issue. The RMT-8IR remote control and the 8x1 DVI DL/SL Switcher both have
banks of DIP (Dual Inline Package) Switches for configuring the remote channel
that both units use to communicate. These settings must exactly match each
other for proper operation.
The DIP Switch bank on the RMT-8IR is located underneath the battery cover.
DIP Switch banks for the 8x1 DVI DL/SL Switcher are located on the underside of
the unit beneath a black piece of metallic tape. One DIP switch bank (4-switch)
is for the adjustment of remote control frequencies and switch behavior. The
other DIP switch (8-switch) is reserved for Gefen use only. DIP Switches 1 and
2 on the RMT-8IR directly correspond to DIP Switches 1 and 2 on the 8x1 DVI
DL/SL Switcher. Only switches 1 and 2 (of 4 in that bank) are used for IR Code
settings.
