INTRODUCTION
Thank you for purchasing Gefen Inc.’s ex•tend•it USB•241
KVM switcher series. The USB•241 switches your moni-
tor and USB between two computers and is expandable
up to 8 USB•241 units for a total of 16 computers. The
USB•241 switcher is designed to be placed close to the
computers. The USB and Video output of the USB•241
unit can be extended with the ex•tend•it CAT5•2000I USB
product, up to 300 feet away. Alternately, the USB•241
can be switched remotely using the RMT-16 wired remote
control. Video and USB can be extended up to 25 feet
away without the need for an additional amplifier.
Theex•tend•itUSB•241unitcanbeconfiguredforalltypes
of monitors and resolutions. Each CPU needs to be con-
figured for the specific monitor size and resolution. For all
new computers from year 2000 and up, the resolution of
the monitors can be adjusted from the control panel of
each computer.
The ex•tend•it USB•241 can be configured for different
modes of switching by setting dip switches on the front
panel. The default model comes with all the switches off.
It allows switching between two CPUs. In order to control
more than two CPUs, the dip switches are set to Master
and an address from 1 to 8 is selected on the selector
switch.
The ex•tend•it USB•241 can be connected together with
other USB•241 units using an expansion cable between
the USB•241 units.
Another useful configuration is for dual monitor switching.
By using two USB•241 units, and a setup for the two units
as Master and Slave configuration, two computers using
two monitors each, can be switched with the USB•241.

READ THESE NOTES BEFORE INSTALLING OR
OPERATION OF THE USB•241 SYSTEM
1. The ex•tend•it USB•241 units were designed to
operate on any type computer with USB keyboard/
mouse and analog video. Using the USB•241
equipment with non USB computers is not
guaranteed or recommended.
2. Powering down an ex•tend•it USB•241 unit while the
computer is on can cause the USB signal to freeze.
It is recommended to always leave the power of the
USB•241 unit ON.
3. The monitor dip switch setting on the ex•tend•it
USB•241 unit needs to be configured to the type of
monitor used. Incorrect dip switch setting will result
in no picture or incorrect picture size upon start up
of the computer. Latest model computers require no
dipswitch setting. See detail on page 11 for
configuration.
4. Selecting Setting switches on the front panel can be
updated during any time of operation. See details on
page 12 & 13.
5. When using a local keyboard in a system that
includes the use of a CAT5•2000S unit and the
USB•241, the USB signal is connected to the
USB•241 directly from the computer. The video is
connected from the CAT5•2000S local monitor out.
