4、According to the wireless router (AP) that you connect to, you can modify the
parameters of wireless settings, including network name, encryption, keys and the IP
address of network settings.
5、Modify the working mode settings, select the "enable auto-work mode" option and set
the parameters according to what you want.
6、After modifying parameters as shown below, click "submit " and select "manually reset
later" in the pop-up dialog box.
Figure3-3 Modify parameters of UART-WIFI module
2.3 Testing
1、Run TCP / UDP debugging software, create a TCP Server whose detecting port is

60000.
2、Run serial debugging software, such as RealTerm.exe in this case. Modify parameters.
Figure3-5 modify the parameters of ComMaster
3、Repower the serial adapter plate(or press the reset button), and the TLG10UA03
module will reset and automatically connect to the network and TCP server. Then you
can begin your transmission test between ComMaster and the TCP/UDP test tools.

3Configuration management manual
3.1 Configuration through configuration management software
3.1.1 Introduction
We offer a configuration hypervisor that can manage TLG10UA03 module expediently，
for configuration querying、config、function test etc，its main function includes,
module management
managemant through serial
managemant through wireless connection
parameter configuration
modify/query module parameters
import/export parameters
modify parameters for a group of modules
resume to default setting
function test
wireless network command test
socket command test
AT+ instruction test
firmware upgrade
system information query
3.1.2 Module management
3.1.2.1 Management through serial connection
1、Connect the TLG10UA03 module to the serial adpater，then turn it power-on；
2、Open the UART-WIFI configuration hypervisor，select the port number of connection
from port list，you can select ‘auto’ unless you make sure；
3、Click ‘search module’，if the connection port is selected to ‘auto’ and the computer has
more than one serial，it maybe expend a long time for searching, The following sketch
map will show after search completed：

figure5-1 serial connection sketch map
3.1.2.2 Management through wireless connection
Note：Using this function needs to choose correct wireless adapter and install wireless
driver correctly.
1、Plug the wireless adapter in computer，it’s shown as the figure 2-5；
2、Install wireless driver，the successful result is shown as the following sketch map；
Figure5-2 Install wireless driver
3、Open the UART-WIFI configuration hypervisor，if the driver is installed successfully，
setting frame of wireless connection will be in activation status；
4、Click ‘setting’ button，input system password（only the module of which the system
password matchs with the setting can be scanned）；

5、Select scan channel from channel list. It will scan all channels from 1 to 14 ,if ‘auto’ is
selected；
6、Click ‘search module’，if channel is selected to ‘auto’，it will expend a long time to
search，the completed result is shown as the following sketch map：
Figure5-3 sketch map of wireless connection
3.1.3 Configuring parameter
This section offers the function of fast querying/modifying configuration parameter of
module for user.

figure5-4 configure parameters
3.1.3.1 Refresh parameter
User can refresh the configuration parameter from wireless module and show in the
display interface through clicking the ‘refresh parameter’button.
3.1.3.2 Submit modification
User can click ‘submit modification’ button after modifying configuration parameter
（including parameter in advanced setting）in the display interface to save the parameters
into wireless module. New parameters will become effective until wireless module has
been reset,user can select to reset at once or manually reset later in pop-up dialog box
after modifying，it’s shown as the following sketch map,

figure5-5 sketch map of submitting modification
3.1.3.3 Restore to factory setting
User clicks ‘’ button to restore the configuration parameters of the wireless module into
factory status. After restoring，the factory setting becomes effect until the module has been
reset.

figure5-6 sketch map of restoring to factory setting
3.1.3.4 Import/export parameters
User can save all configuration parameters in display interface to the specified
configuration file through clicking the ‘export parameters’button, and apply all parameter
which are saved in configuration file through clicking ‘import parameter’ button. What
should be noted is that, using import parameter function only imports parameters to the
display interface，the imported parameters can be wrote in wireless module actually until
clicking the ‘submit modification’.

figure5-7 sketch map of Importing parameters
3.1.3.5 Group modification
Group modificatio will be activated when configuration hypervisor has searched for more
than one wireless module. If user selects the function，the modified parameters will be
applied to all of the wireless modules automatically through clicking ‘modify all’. This
