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.

Download from Www.Somanuals.com. All Manuals Search And Download.  
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:  
Or contact Technical Support for further assistance (see page 20).

Advanced Setup – Pairing a LEX unit and a REX unit  
The following instructions are for advanced users only.  
These instructions should only be executed if specifically required and if you  
are comfortable with the operations. Under normal operating conditions,  
you should never need to pair a LEX unit and a REX unit.  
Paired units are defined as a LEX unit and a REX unit that are aware of each  
other’s unique address and communicate exclusively.  
Pairing is accomplished by infrared (IR) communication through the IR  
windows on the LEX unit and the REX unit; pairing information is not sent  
over the 802.11g radios. The IR communication distance is limited to an  
approximate distance of 20 cm.  
NOTE: The WiRanger’s LEX unit and REX unit are shipped paired  
from the factory.  
NOTE: If the Pair/CH button is pressed whether accidentally or  
purposefully and the LEX unit and the REX unit are not able  
to communicate via the IR interface no effect in operation  
will be detected and pairing will not occur.  
1. Place the LEX unit and the REX unit 5 cm apart from each other  
with their IR windows pointed directly at each other. The IR  
windows must have a clear and unobstructed view of each other.  
2. Power on both the LEX unit and the REX unit and wait for  
approximately 20 seconds before proceeding to step 3. If the units  
are already on, proceed to step 3.  
3. Press the Pair/CH button on either unit for approximately 1 second.  
Upon release of the button the Host, Link and Activity LED’s on  
both the LEX unit and the REX unit should begin to blink rapidly.  
NOTE: DO NOT remove power while LED’s are blinking.  
NOTE: If step 3 is attempted too early after power up, the pairing  
procedure will not occur. Wait a few seconds longer and  
retry step 3.  
NOTE: If the rapid blinking of the LED’s does not occur, confirm  
that the IR windows on the LEX unit and the REX unit are  
unobstructed, pointed at each other, and are 5 cm apart.  
Retry pressing the PAIR button. If the LED’s still do not  
blink upon release of the button unplug both units for at least  
10 seconds and return to step 1.

4. Wait for the LED’s on the LEX unit and the REX unit to stop  
blinking and for the Link LED to turn on.  
NOTE: If the Link LED does not turn on within 30 seconds return to  
step 1.  
5. The LEX unit and the REX unit are now Paired and are free to be  
unplugged and moved to their desired locations.  
6. Once the units are installed in their specific locations, connect a  
USB cable between the WiRanger and the host PC to confirm the  
WiRanger’s operation. If the system has been installed and paired  
correctly it should be listed in Device Manager (for Windows  
installations), or System Profiler (for Mac OS X installations) under  
Universal Serial Bus controllers as a “Generic USB Hub”.

3. Using standard Wireless Networking software,  
confirm if there are any other 802.11g radio  
networks operating on or near the same  
channel as the WiRanger. (Note you can  
determine the current WiRanger Radio  
Channel using the procedure on Page 9.)  
b) There is too much  
Radio Interference.  
c) The WiRanger is  
not configured  
correctly.  
4. Configure all conflicting 802.11g products so  
that they use evenly separated Radio  
Channels. Optimal separation is five  
channels, so channels 1, 6, and 11 will  
provide the least interference between  
themselves.  
d) The WiRanger is  
malfunctioning.  
If the WiRanger cannot establish wireless  
communications at short range:  
1. Confirm that the Radio Antennas are properly  
secured to the antenna connectors of the  
WiRanger.  
2. Confirm the Radio Channels of the LEX unit  
and the REX unit as described on Page 9.  
3. If the LEX unit and the REX unit are not  
configured with the same Radio Channels,  
then set both units to the same channel as  
described on Page 10.  
4. If both units are already configured to the  
same Radio Channel, then attempt the Pairing  
Procedure described on Page 12.

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.
