User Guide
Wireless Operation
The LEX unit and REX unit wirelessly communicate over the IEEE
802.11g radio protocol at a distance up to 30 meters. The actual
communications distance will vary greatly depending on the amount and
type of physical obstacles and radio interference in your area. In
general, the WiRanger should have similar range to that of a normal
802.11g router or access point.
The LEX unit and REX unit of this WiRanger are “Paired” at the factory
so that they will only communicate with each other, even if other
WiRanger’s are installed near by.
NOTE:
Under normal operating conditions, you should never need to
“Pair” the units. However, if absolutely required, the units
can be “Paired” using the procedure listed on Page 12,
Advanced Setup – Pairing a LEX unit and a REX unit.
The IEEE 802.11g standard allows for different wireless devices to
operate on different Radio Channels. This means that your 802.11g
wireless router or access point can co-exist with the WiRanger, if they
are configured to operate on different channels.
5
Your WiRanger will be pre-configured to operate on 802.11g Radio
Channel 11. Ideally, your other 802.11g products should be configured
to work on a channel that is at least 5 channels apart from the one used
by the WiRanger.
For example, if the WiRanger is on channel 11 and you also have a
802.11b/g router. Then configure the router to operate on channel 6, or
lower.
NOTE:
If required, you can view or change the current WiRanger
802.11g Radio Channel. See Advanced Setup – Viewing and
Changing the 802.11g Radio Channel on Page 9 for
instructions.
NOTE:
The WiRanger does not broadcast an SSID and will not be
visible to a wireless network scan.
USB Cables
USB cables have two distinct connectors. The Type A connector is used
to connect the cable from a USB device to the Type A port on a
computer or hub. The Type B connector is used to attach the USB cable
to a USB device.

Compatibility
The WiRanger complies with USB 2.0 specifications governing the
design of high-speed USB devices. However, because of the data rate
limitations inherent in the IEEE 802.11g radio platform, Icron
Technologies Corporation does not guarantee that all USB devices are
compatible with the WiRanger.
In particular, webcams that use the BULK transfer protocol are not
supported. For more information on potential incompatibilities, please
see the FAQ page of the Icron Technologies Corporation website:
http://www.icron.com/products/usb/faq.php
Or contact Technical Support for further assistance (see page 20).

Limited Hardware Warranty
Icron Technologies Corporation warrants that any hardware products
accompanying this documentation shall be free from significant defects in
material and workmanship for a period of one year from the date of
purchase. Icron Technologies Corporation’s hardware warranty extends to
Licensee, its customers and end users.
Hardware Remedies
Icron Technologies Corporation’s entire liability and the Licensee’s
exclusive remedy for any breach of warranty, shall be, at Icron Technologies
Corporation’s option, either (a) return of the price paid or (b) repair or
replacement of hardware, which will be warranted for the remainder of the
original warranty period or 30 days, whichever is longer. These remedies are
void if failure of the hardware has resulted from accident, abuse, or
misapplication.
Limitation of Liability
The hardware warranty set forth in this agreement replaces all other
warranties. Icron Technologies Corporation expressly disclaims all other
merchantability and fitness for a particular purpose and non-infringement of
third-party rights with respect to the hardware. Icron Technologies
Corporation dealer, agent, or employee is authorized to make any
modification, extension, or addition to this warranty. Under no
circumstances will Icron Technologies Corporation, its suppliers or licensors
be liable for any costs of procurement or substitute products or services, lost
profits, loss of information or data, or any other special, indirect,
consequential, or incidental damages arising in any way out of the sale of,
use of, or inability to use Icron Technologies Corporation product or service,
even if Icron Technologies Corporation, its suppliers or licensors have been
advised of the possibility of such damages. In no case shall Icron
Technologies Corporation, its suppliers and licensors’ liability exceed the
actual money paid for the products at issue. Because some jurisdictions do
not allow the limitation of implied warranties of liability for incidental,
consequential, special, or indirect damages, the above limitation may not
always apply. The above limitations will not apply in case of personal injury
where and to the extent that applicable law requires such liability.
