Chapter 1 Establishing WLAN Connection
This chapter will show that how to establish WLAN connection step by step. Related network
and TCPIP setting are also provided in this chapter.
1.1 Network Setting
1. Ticking on icon “W” then select ”Enable WLAN”. Please refer to Fig1.1 as shown below.
Fig 1.1 Enable WLAN
2. After enabling WLAN, screen display will be like Fig1.2 if there are no network setting. Or
double click WLAN tray icon to open network setting like Fig1.3. A list of Access Point and
signal strength ( the larger the value the better ) detected will be displayed in the middle
part of the screen. Ticking on the Access Point to be connected and select “Connect”
( please refer to Fig1.4 ).

3. Configuration of the Access Point：
a. Has the WLAN and configuration function been enabled？
b. Is there any limitation set on MAC address？
c. Is there any limitation set on connections been made？
d. Is there any special connection configuration needed？Is there any special
authentication installation needed on PT-90？
e. If using DHCP：has the DHCP function been enabled？if DHCP function has been
enabled, can correct IP address be acquired ( if connections made limitation or IP
address range limitation is reached, correct IP address will not be acquired )？
f. If using static IP：have correct IP address, subnet mask, and gateway been set
correctly？ Is there any conflict on the IP address specified？
(All these AP configurations are critical to WLAN connection！)
g. When the AP configuration function been selected, all AP-related properties will be
displayed, i.e. Encryption、Authentication、Network、Key index、EAP type and
properties setting ( as shown in Fig1.5 ~ Fig1.8 ).

4. Example: Properties of the AP ( named argoxnet ) are:
Encryption = WEP
Authentication = Open
Network Key ( or Password ) = 1234567890abc( total 13 digits )
The configuration procedures are:
a. Ticking “argoxnet” then enter the configuration process;
b. As in Fig1.9, set “Encryption” as “WEP” and set “Authentication” as “Open”;
c. As in Fig1.10, cancel “The key is provided automatically” then enter “Network Key ( or
Password )” ( i.e. 1234567890abc ) and set “Key Index” to “1”;
d. Ticking “OK” to establish the connection.

5. After connection, check if the IP address is correct ( as shown in Fig1.11 and Fig1.12 ). If
the IP address is not correct, please tick on “Renew” to re-establish the connection ( as
shown in Fig1.13 ).

If, by any chance, after several “Renew” and still no correct IP address can be acquired,
please check AP and the network first.

6. Ticking on “Advanced” can bring you into WLAN advanced configuration process as
shown in Fig1.14, Fig1.15, and Fig1.16 below.
a. By selecting different Access Points, you can set up the priority of Access Points to be
connected. When the connection with first Access Point fails, PT-90 will proceed
connecting with the second Access Point and so on. If the connection with the first
Access Point is successful, there will be no connection attempt process made.
b. Double ticking on the Access Point will initiate the configuration function so all related
features can be re-configured.
c. If there is any problem found on the connection configuration, you can delete all
feature configurations then re-configure all features.

1.2 TCPIP Setting
1. Start MenuSettingsNetwork and Di…enter Network Configuration ( as shown
in Fig1.17 );
2. Select “SDIO86861” then “” will bring you into properties selection ( as shown in
Fig1.18 );
3. First page of properties selection can set up IP address, via DHCP or static IP ( as
shown in Fig1.19 );
4. Second page can proceed DNS and WINS configurations ( as shown in Fig1.20 ).

1.3 WLAN Tray Icon
When WLAN service is active, it displays an icon in the windows system tray on Windows CE.
The service displays one of the following icons:
 Enable/Disable WLAN.
 Not Connected.
 The RSSI for the current AP is weaker -90 dBm.
 The RSSI for the current AP is stronger than -90 dBm and weaker than -81.
 The RSSI for the current AP is stronger than -81 dBm and weaker than -71.
 The RSSI for the current AP is stronger than -71 dBm and weaker than -67.
 The RSSI for the current AP is stronger than -67 dBm.

Chapter 2 Using WLAN Setting File
There is another way in PT90 to set WLAN setting by setting file. WLAN setting file is
described in more detail in this chapter.
2.1 Flow Chart
1. Copy WLAN.ini file on \User Application and do cold reset.
2. According to WLAN.ini file to set WLAN settings.
3. When performance setting to be changed, it will warm reset automatically. After warm
reset, the new performance setting will be applied.
2.2 Setting File Description
After PT90 do cold reset. PT90 can detect whether WLAN.ini file exist on \User Application. If
the file is existed, PT90 will set WLAN settings via WLAN.ini file; if the file isn’t existed on \User
Application, PT90 will do nothing.
Setting file can set according to different need and it only needs to write in the items that to
change in setting file. Content of WLAN.ini divided into three section and change via
requirement.
2.2.1 WLAN Section

a. AutoOn：0/1,0 is close, 1 is open, default is 0。
b. Network：set network, it can set several networks and divided into symbol comma(,),
and add setting on [Network Section1] area, the sequence will with by left go to

Chapter 3 Using WLAN Setting
The WLAN setting provides main, profile and performance settings. Double click WLAN tray
icon to open network setting (as shown Fig3.1). Press “Setting” button to enter WLAN setting
(as shown Fig3.2). WLAN setting has three windows: Main, Profile and Performance. Each
window is described in more detail in this chapter.

3.1 Main Window
A Main window is shown in Fig3.3. Here are the highlights of the Main window.
 Active Profile: Selected a profile as the active profile. The settings for that profile
become active after press “Apply” button (as shown in Fig3.4).
 Auto On: When this is checked, WLAN enable when device startup. When this is
unchecked, WLAN disable when device startup.
 Version: Indicates the WLAN setting version.
Fig3.3 Main Window Fig3.4 Active Profile
If active profile is specified, the setting for that profile will active when device startup. In
this situation, the WLAN setting file will be ignored. The active profile setting may
include performance setting. When performance setting to be changed, it will warm
reset automatically. After warm reset, the new performance setting will be applied.

3.2 Profile Window
A Profile window is shown in Fig3.5. Profile settings are stored in the registry as part of a
configuration profile. On the Profile window, three actions are available. Create a new profile
by press “New” button. Give the profile a new name by press “Rename” button. Delete the
profile by press “Delete” button.

Here are highlights of the Profile Window.
 Profile: Select a profile to be viewed or edited (as shown in Fig3.6). After select a profile,
the setting information of the profile will display like Fig3.7 and Fig3.8. The “Rename” and
“Delete” button only available when a profile is selected.
