WARNING -Disclaimer
Tellus Group Corp., its Sales, Manufacturing and Design Organizations, Reps., Distributors,
VARs and distribution channels are absolutely not liable for any death, injury, property
damage, loss of data, loss of business of any other unmentioned loss. The aforementioned
entities are not liable even in the event that any of these entities were apprized of the specifics
or generalities of an application or intended installation at any time.
Radio Linkages of any type can be fragile and tenuous. Over 1/5th of the entire population of
the world now owns cellular telephones, and as any user of a cell phone knows, the cell
phone radio communications link may be easily disrupted or completely lost simply by turning
your head or by other small environmental movements or changes. This clearly demonstrates
to everyone the fragility of any radio link and why radio should not be used for critical
implementations, or where death, personal injury, physical damage, property damage or
environmental damage may result.
Tellus Group Corp.’s products are not designed, manufactured, or intended for use or resale
as online control equipment in hazardous environments requiring fail-safe performance, such
as, but not limited to the operation of nuclear facilities, aircraft navigation, vital communication
systems, air traffic control, life support machines, weapons systems, or any industry in which
environmental disruptions or technology failure could lead directly to death, personal injury,
physical damage, property damage or environmental damage.
Do not use this device in applications for
which any failure of the wireless link or any
data error may cause death, injury or damage
of any kind.

1. Introduction
Thank youfor purchasing this 802.11b WLAN serial module (hereafter we call this product as
The Module).
The Module is designed for embedded into device that uses battery power and has
very limited space. The Module will replace the device’s RS232 cable that connects
to host PC. Via IP network compatible wireless connection,The Module transfers byte stream
between device and host PC. The Module is compliant with 802.11b protocol
standard. It can operate at ad-hoc mode or infrastructure mode, and support 64/128-bitsWEP
security. The design goal for The Module is to provide an OEM embedded device with
compact and small size, easy to use and low power consumption.
1.1 Features:
ŸProgrammable baud rate (9600, 38400, 57600, 115200 bps)
ŸFull-duplex (serial data in, and serial data out)
ŸHardware flow control
ŸFirmware upgrade through RS232 port
ŸSupports full mobility and seamless roaming from cell to cell
ŸEasy set up via Console or Desktop Utility
ŸLED status and activity indicators for easy installation, monitoring and diagnostics
ŸLink to WLAN Access Point (referred as infrastructure mode)
ŸLink to another WLAN station (referred as “ad hoc” mode)
1.2 Application
The Module provides the RS232 to WLAN converting function (Figure 1-1. For the device
(especially the device) that needs to replace the RS232 cable with WLAN, The
Module is the right choice.

Configuration –Web Browser
To configure The Module, there are two methods can be applied:
- Web Browser Configuration (This section)
- Command Mode Configuration (refer to section 3)
For Web Browser configuration, there are two methods to enter the web browser:
ŸDirect Web Browser
Open the web browser and enter http://192.168.1.250 in the browser’s address box.
192.168.1.250 is the default IP address (refer to 2.4).

You will need to configure the IP address of your computer to be within the same
subnet as The Module and AP have for the initial configuration(please refer to
Appendix A).
ŸAuto Search Utility
The Auto Search Utility provides the locator function that allows you to find the available
WLAN Serial Modules in the network. Follow the steps below to install the utility:
- Stored the supplied Auto Search Utility file into your PC. Double Click “setup.exe”
