Introduction
This guide explains how to install the following software on a Linux based desktop or laptop
computer:
- AW-GD200 Driver for Linux system
This adapter can be used in a non-PC device to easily enable Wireless connectivity.
1.1 Installation
The installation procedure includes two main steps:
1. Compile the Driver
2. Install the Driver
1.1.1 Adapter Linux Driver
The driver is distributed in source-code format. In order to compile the driver, you need to have the
Linux source tree installed in your desktop/laptop computers, preferably in the /usr/src/linux
directory. This driver has been tested with Linux version 2.4.22 and compiled with gcc 3.2.2. The
host Linux system that was used to compile and test the driver is based on Slackware 9.1
distribution.
1.1.2 Installation and Configuring the Linux Source Tree
The requirements for the environment to install and configure the Linux source tree are:
- Linux kernel source v2.4.22
- GCC v3.2.2
- Wireless Tools version 26
Then you have to follow the steps below to complete the installation and configuration process.
1. Download the Linux kernel file from http://www.kernel.org.
2. Untar the source in the /usr/src directory.
3. Create a symbolic link to the Linux source tree to a directory called "linux".
4. Run "make menuconfig" in the Linux directory and then enable the Wireless LAN under
"Network Device Support"/"Wireless LAN (Non Hamradio).
5. Configure any other options as required.
6. Exit and save the configuration.
The Linux kernel does not to be compiled when you compile the driver. However, you must install
the same version of the kernel which the driver is compiled against to run the driver.
1.1.3 Compile the Driver
If the Linux source tree is not presented in the default Linux directory, you can modify the
KERNELDIR parameter in the Makefile to direct to the location of the kernel source.
Then you can follow the steps below to compile the Linux driver:
a) Type “make clean”. Verify that there is no legacy file in the target directory.
b) Type "make". Verify that the file “deep31.o” is built and placed in the target directory.
c) The deep31.o is the driver compiled as a module for the current kernel. The Makefile also tries
to copy the driver to the /lib/modules/2.4.22/pcmcia directory so that the driver can be easily
loaded at boot time.
If you want to remove debug options -DDEBUG and –DDBG, they can be removed from Makefile
CFLAGS variable.

1.1.4 Install the Driver
After inserting the adapter, you can run
insmod deep31.o
to load the driver into the kernel.
1.1.5 Overall Installation Procedure
As a summary, the overall installation procedure for Linux driver is as below:
1. Extract the source into any directory. For example,
cd /usr/src
tar xvzf mb31ep_sdk_2_1_x_x.tar.gz
2. Go to the created directory and then compile the source code
cd MB31-DeepLinux
make clean
make
This should create the file deep31.o which is the driver as a loadable module.
3. There are four options to operate the driver.
a) To load this driver as AP mode, you can type
insmod deep31.o active=”deep_ap”
b) To load this driver as Client mode, you can type
insmod deep31.o active=”deep_wb”
c) To load this driver for firmware upgrade in AP mode
insmod deep31.o active=”change_ap_mode”
d) To load this driver for firmware upgrade in Client mode
insmod deep31.o active=”change_wb_mode”
(or You can execute/modify the run1 script in the source file directory to load driver)
4. If debug is enabled in the Makefile (-DDEBUG -DDBG) then debug messages can be printed
out through the klogd facility of the Linux kernel. The standard log files are in folder /var/log/debug,
folder /var/log/messages and folder /var/log/syslog.

2.0 Configure a wireless network interface
The following describes the configuration of AW-GD200 wireless driver using the wireless
extension tools.
2.1 iwconfig
iwconfig is dedicated to the wireless interfaces. It is used to set the parameters of the network
interface which are specific to the wireless operation (for example: the frequency). iwconfig may
also be used to display those parameters, and the wireless statistics.
The format of the iwconfig is depicted as following:
iwconfig
iwconfig -help
iwconfig interface
iwconfig interface [parameters]
Parameters
[essid X] [nwid N] [freq F] [channel C] [sens S] [mode M]
[ap A] [nick NN] [rate R] [rts RT][frag FT] [txpower T]
[enc E] [key K] [power P] [retry R] [commit]
Please refer the wireless extension tool manual for more information.
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one of the
following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
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.
FCC Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this
equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited
to channels 1 through 11.

This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
The transmitter module may not be co-located with any other transmitter or
antenna.
As long as 2 conditions above are met, further transmitter test will not be
required. However, the OEM integrator is still responsible for testing their
end-product for any additional compliance requirements required with this
module installed (for example, digital device emissions, PC peripheral
requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for
example certain laptop configurations or co-location with another transmitter),
then the FCC authorization is no longer considered valid and the FCC ID can
not be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The final
end product must be labeled in a visible area with the following: “Contains TX FCC
ID: TLZ-GD200
Manual Information That Must be Included
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the users manual of the
end product which integrate this module.
The users manual for OEM integrators must include the following information
in a prominent location “ IMPORTANT NOTE: To comply with FCC RF
exposure compliance requirements, the antenna used for this transmitter must
be installed to provide a separation distance of at least 20 cm from all persons
and must not be co-located or operating in conjunction with any other antenna
or transmitter.
