INTRODUCTION
Congratulations on your purchase of the USB 400 FO. 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 400 FO
The USB 400 FO Extender supports all USB 2.0 devices, extending to 1640 feet
(500 meters) away from the USB source using 50/125µm multi-mode ber, or
900 feet (275 meters) using a 62.5/125 µm multi-mode ber. The receiver end is
also a four USB 2.0 hub.
By using ber optic cables, the USB 400 FO 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 400 FO 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 ber 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 400 FO 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 400 FO will connect with any USB-compliant
peripheral in all operating systems supporting USB 2.0.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE USB 400 FO
This equipment provides 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 400 FO 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 400 FO signal controls the keyboard, mouse, trackball, and other USB
peripherals using send and receive units. The USB signal is extended by using
multi-mode ber optic cabling.
The USB 400 FO uses dual multi-mode LC ber 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
operation.
Requirements:
To complete the installation, you will also require the following items that are not
included with the product:
• USB 1.1 or 2.0 Compatible computer (host computer) with a USB compliant
operating system

• 2-strand multi-mode ber optic cable with Duplex LC connectors (if using
surface cabling) OR, 2-strand ber optic cabling with two information outlets
and two 2-strand ber 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
ber optic cabling. Two strands of 50/125μm (1640 feet max.) multi-mode ber or
62.5/125μm (900 feet max.) multi-mode ber cabling are required. The cabling
subsystem must provide a duplex connection with crossover, and must be
terminated with Duplex LC connectors at both ends.
