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

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.

reveal the battery compartment. Insert the included battery into the open battery slot.

RMT-8IR REMOTE AND 8X1 SWITCHER CONFIGURATION  
How to Resolve IR Code Conicts  
In the event that IR commands from other remote controls conict 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 conguring 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.
