The Gefen 8x1 DVI DL/SL Switcher
The rack-mountable Gefen 8x1 DVI dual-link/single-link 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 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.
