INTRODUCTION
Congratulations on your purchase of the 8 x1 DVI-DL KVM 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 KVM DL/SL Switcher
The rack-mountable Gefen 8x1 dual link/single link DVI KVM 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 that supports both
Macintosh and IBM-PC computers, the 8x1 DVI KVM DL/SL Switcher shares one
DVI display with up to eight computers or other DVI video sources. A single USB
2.0 port, keyboard & mouse ports, and an analog audio jack are also switched.
The switcher saves space on your desktop by eliminating a crowded workspace
full of DVI monitors, keyboards & mice, and USB and audio cables. Switching of
DVI sources is easy and reliable.
How It Works
The DVI monitor is connected to the 8x1 DVI KVM DL/SL Switcher’s output. Up
to eight DVI video 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 DVI
video signal appears on the shared monitor. DVI Video sources (and optionally
keyboards & mice, USB and audio cables) 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 KVM DL/SL SWITCHER
•
The 8x1 DVI KVM DL/SL Switcher will take any of up to eight (8) DVI dual-
link or 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 8x1 DVI KVM DL/SL Switcher is housed in a metal box for better RF
shielding.
Computers must be turned on one at a time and the switcher must be
selected to the computer that is booting up. 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 a EDID storage device (DVI DETECTIVE; part# EXT-DVI-EDIDN) that
will constantly supply each computer with an EDID. In this scenario, each
computer must have a detective placed between itself and the switcher.
Then, each computer can boot up in any order and at anytime, regardless of
which computer the switch is selected to.

CONNECTING & OPERATING THE 8X1 DVI KVM DL/SL SWITCH
How to Connect the 8x1 DVI KVM DL/SL Switcher to your devices:
1. Connect your computers’ DVI, USB, and Audio sources to the 8x1 DVI KVM
DL/SL Switcher inputs using the supplied cables.
2. Connect your DVI display to the DVI output of the 8x1 DVI KVM DL/SL
Switcher using a user-supplied DVI cable.
3. Connect your USB and audio devices to the USB and audio outputs with user-
supplied cables.
4. Connect the included 5V DC power supply to the Switcher by by screwing its
5V DC power supply tip into the receptacle in the rear of the unit, then plug it
into the wall.
5. Turn on the DVI display or projector first, then the DVI video sources/
computers.
Note: Computers must be turned on one at a time and the switcher must
be selected to the computer that is booting up. This is so that monitor
information (EDID) can be 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 a EDID storage device (DVI DETECTIVE;
part# EXT-DVI-EDIDN) that will constantly supply each computer with
an EDID. In this scenario, each computer must have a detective placed
between itself and the switcher. 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 KVM DL/SL Switcher:
1. Use the RMT-8IR remote control to remotely switch between DVI video
sources.
2. Alternatively, use a RS-232 control system or the front panel selection
button.

8X1 DVI KVM DL/SL SWITCHER 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 KVM 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 KVM 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 KVM 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 KVM DL/SL Switcher. Only switches 1 and 2 (of 4 in that bank) are
used for IR Code settings.
