Congratulations on your purchase of the 2x1 DisplayPort KVM. 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 2x1 DisplayPort KVM
The 2x1 DisplayPort KVM Switcher allows effortless switching of DisplayPort
between two computers using just one display and one USB2.0 port for a
keyboard and mouse. Audio, video and control signals are switched for each
computer upon selection, providing an easy and effective method of accessing
two computers from one workstation without the hassle of network. Switching can
also be performed through the front panel Select button, IR remote control or via
RS232.
How It Works
DisplayPort’s plug-and-play construction and compact connector enables faster,
easier installations with less chance of errors.
Connect a DisplayPort display and USB 2.0 keyboard/mouse to the Switcher’s
outputs. Connect both computers’ DisplayPort, USB and audio ports to the
Switcher’s inputs using the supplied cables. The Switcher is compatible with both
Macintosh and PC keyboards, mice and displays.
Note: If the source and/or display is not DisplayPort compliant, a protocol-
specific protocol adapter will be required in order to connect the source to the
Switcher and/or the Switcher to the high-resolution display.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 2X1 DISPLAYPORT KVM
• Display Information (EDID) is normally required by source/host devices to
determine the capabilities of the attached peripherals. The 2x1 DisplayPort
KVM features complete EDID passthrough. This means that when EDID
is present on the output device, it will be passed to the active source/host
device.

RMT-2IR REMOTE CONTROL DESCRIPTION

9
To use the RMT-2IR 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.

How to Resolve IR Code Conflicts
In the event that IR commands from other remote controls conflict with the
supplied RMT-2IR remote control, changing the remote channel will alleviate
this issue. The RMT-2IR remote control and the 2x1 DisplayPort KVM 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-2IR is located underneath the battery cover.
DIP switch banks for the 2x1 DisplayPort KVM are located on the underside of
the unit beneath a black piece of metallic tape. Switches 1 and 2 on the RMT-2IR
directly correspond to DIP Switches 1 and 2 on the 2x1 DisplayPort KVM. Only
switches 1 and 2 (of 4 in that bank) are used for IR Code settings.
