INTRODUCTION
Congratulations on your purchase of the USB-400FO. 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 USB-400FO
The USB-400 FO Extender supports all USB 2.0 devices, extending to 1640 feet
(500 meters) away from the USB source. The receiver end is also a four USB
2.0 hub.
By using fiber optic cables, the USB-400FO extends a long distance from the
location of a computer. It provides an EMI-free solution for using USB at remote
locations.
How It Works
The USB-400FO sender unit is connected to the source using the supplied USB
short cable. The USB peripheral(s) are connected to the receiver unit at the
remote end. Two LC-terminated multi-mode fiber optic cables are used to link the
sender to the receiver. The Receiver unit must be powered by a 5V DC power
supply. The Sender unit is powered by the USB bus.
Applications
The USB-400FO is invaluable for applications where complete control of devices
is necessary when using USB when placing in restricted areas, such as medical
facilities and oil rigs. The USB-400FO will connect with any USB-compliant
peripheral in all operating systems supporting USB 2.0.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE USB-400FO
This equipment is a new version replacing the existing part number,
EXT-USB-400FO, and can provide outstanding extension facilities for any device
or USB application that requires a peripheral connection over a distance, such as
a USB camera or USB hard drive, keyboard and mouse.
The USB-400FO works like a USB hub with extension capabilities over a distance of
up to 1,640 feet. This means, for example, that a remote USB sensor can be placed
at a safe distance from the sender unit in situations that demand this type of security.
The USB-400FO signal controls the keyboard, mouse, trackball and other USB
peripherals using send and receive units. The USB signal is extended by using
multimode fiber optic cabling.
The USB-400FO uses dual multi-mode LC fiber optic cables to connect the sender
and receiver units.
FCC Radio Frequency Interference Statement Warning
This device complies with Part 15 of the FCC rules. Operation is subject to the
following two conditions:
(1) this device may not cause harmful interference, and (2) this device must
accept any interference received including interference that may cause undesired

cabling) OR, 2-strand fiber optic cabling with two information outlets and two
2-strand fiber optic patch cords with Duplex LC connectors (if using premise
cabling) .
The Sender Unit and Receiver Unit are interconnected by up to 500 meters of
fiber optic cabling. Two strands of 50/125m (500m) MMF or 62.5/125m (275m)
MMF cabling are required. The cabling subsystem must provide a duplex
connection with crossover, and must be terminated with Duplex LC connectors
at both ends.

TROUBLESHOOTING
Verifying Installation on PC or Macintosh Computers
1. For Windows users (2000, XP, Vista, Windows 7), open the Device Manager
to confirm that the USB-400FO has installed correctly. Expand the entry for
Universal Serial Bus controllers by clicking the + sign. If the USB-400FO has
been installed correctly, you should find it listed as a “Generic USB Hub”.
2. For Mac OS X users, open the System Profiler to confirm that the USB-400FO
has installed correctly. In the left hand column under Hardware, select “USB” and
inspect the right hand panel. If the USB-400FO has been installed correctly, you
should find it listed as a “Hub” under the USB high-Speed Bus/USB Bus.
