This manual explains the installation and operation of the Wireless USB 2.0 Extender.
The instructions in this guide assume a general knowledge of computer installation
procedures, wireless network installation requirements, and some understanding of
USB devices.
NOTE: Notes give additional information that could make installation easier.
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
• USB device(s)
NOTE: The Wireless USB 2.0 Extender uses an IEEE 802.11g radio platform to
wirelessly communicate between the Wireless USB 2.0 Sender unit and the Wireless
USB 2.0 Receiver unit using the 2.4GHz radio frequency range. Other products, such
as wireless routers and 2.4GHz cordless telephones, also broadcast in this same
2.4GHz range. Please be aware of potential interference issues with such products
before you begin installation of the Wireless USB 2.0 Extender.
NOTE: The Wireless USB 2.0 Sender unit and the Wireless USB 2.0 Receiver unit of
your new Wireless USB 2.0 Extender have been “Paired” during manufacturing. This
means that they will only communicate with each other, even if other Wireless USB 2.0
Extender units are installed near by.
NOTE: Use only the AC adapters supplied with the Wireless USB 2.0 Extender. Use
of substitute adapters may cause permanent damage to the system and will void the
warranty.
The Wireless USB 2.0 Extender provides the freedom to connect high performance and
high speed USB peripherals anywhere up to 100 feet from the CPU. Instant access to
data (up to 54 Mbps) with zero wires. Work with your USB 2.0 peripherals as if they
were all connected locally.
Wireless Hi-speed USB 2.0 transmits data up to 54 Mbps allowing for little or no
downtime. Compatible with original USB and uses the same cables and connectors.
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE USB 2.0 EXTENDER SYSTEM.
* The wireless USB extender does not support isochronous USB.
* In order to operate properly, the Wireless USB 2.0 Extender sender and receiver units
must not exceed 100 feet.
* To prevent interference, keep sender and receiver in plain sight of each other.

ESTABLISHING WIRELESS COMMUNICATION
The Wireless USB 2.0 Extender will automatically establish a wireless connection
between the Wireless USB 2.0 Sender unit and the Wireless USB 2.0 Receiver unit
once power is applied to both units and they are located within their operating range.
The Link LED on both units will turn on once the wireless connection has been made.
NOTE: It may take up to 30 seconds for the Wireless USB 2.0 Extender to establish
wireless communication. TheActivity LED will flash during this time to indicate that the
radios are powering up.

Set up the host computer in an appropriate location.
Determine where you want to locate the USB device(s).
Determine suitable locations for the Wireless USB 2.0 Sender unit and the
Wireless USB 2.0 Receiver unit such that they will be able to maintain wireless
communication. Physical obstacles and other radio wave emitting devices can
cause interference that will reduce the maximum distance and data rate between the
Wireless USB 2.0 Sender unit and the Wireless USB 2.0 Receiver unit.
If other 802.11g based products will be in operation in the same area, determine
the optimal Radio Channel selection for all wireless products. See the Wireless
Operation section on Page 5 for more information on channel selection.
Plug the power adapter into a suitable AC outlet.
