Wireless Usage and Requirements
Radio transmitting type devices (RF module) are present in models with the wireless option. These devices operate in the 2.4 GHz band (i.e. 802.11B/G/N LAN & Bluetooth).
As a general guideline, a separation of 20 cm (8 inches) between the wireless device and the body, for use of a wireless device near the body (this does not include extremities) is typical. This device should be used more than
20 cm (8 inches) from the body when wireless devices are on and transmitting.
Some circumstances require restrictions on wireless devices. Examples of common restrictions include:
• When in environments where you are uncertain of the sanction to use wireless devices, ask the applicable authority for authorization prior to use or turning on the wireless device.
• Every country has different restrictions on the use of wireless devices. Since your system is equipped with a wireless device, when traveling between countries with your system, check with the local Radio Approval authorities prior to any move or trip for any restrictions on the use of a wireless device in the destination country.
• Wireless devices are not user-serviceable. Do not modify them in any way. Modification to a wireless device will void the authorization to use it. Please contact the manufacturer for service.
Device Power Supply
Use only the external power supply that comes with your thin client. For power and voltage ratings, see the serial number label or regulatory label on your device. For power adapter replacement, contact your Wyse Service
Representative. For proper replacement compare the labels on both mobile thin client and power adapter to ensure that their voltages match.
WARNING: Use of any other power adapter may damage your mobile thin client or the power adapter. The damage caused by an improper power adapter is not covered by warranty.
Battery Information
Model Tx0 contains an internal button cell battery replaceable by Wyse or one of our Authorized Service Centers.

Logging In
TIP: On your initial connection to central configuration it is recommended that you connect using a “wired connection” (plug in the network-connected ethernet cable to your thin client before starting the thin client) to obtain the configurations desired by the administrator (connections, system settings, required certificates and so on). This “wired connection” will also provide any wireless configurations provided by the administrator through the INI files.
If you must initially connect to central configuration through wireless, use the Edit
Wireless Connection dialog box (click System Settings > Network Connections >
Wireless tab > Add) to create a wireless connection where you can enter the SSID and
encryption configurations required/set up by the network administrator (see "Network
After your thin client starts, Administrators (high privilege) can log in to your Home screen using the default user name admin and the default case-sensitive password admin. It is highly recommended that you change the default password by using the User
Administration dialog box in System Settings (see "User Administration").
Note that Thinuser users (low privilege for locked mode end-user) can use the default user name thinuser and the default case-sensitive password thinuser; Guest users (no privileges Kiosk type setup) can use default user name guest and do not need a password.

INI files on the network or local INI files.
• Use INI files from server only - Use this option when you want to use INI files from the specified server only (for example, you do not want to use local INI files or do not want to allow INI use when disconnected from the server for security reasons). When using this option you can direct the thin client to the server location through either of the following ways:
· DHCP Server - Select the Get INI and Upgrade server details via DHCP check box. The DHCP server will direct the thin client (using DHCP options) to the server location where the INI files reside.
· Manually entered server address - Clear the Get INI and Upgrade server
details via DHCP check box and enter the static INI Settings (INI Server URL, and optionally the Username and Password of the server, if selecting the Server
requires authentication check box).
• If server is available, use INI files from server only; otherwise use local INI files -
Use this option when you want to use INI files from the specified server, however, local
INI files can be used if that server is unavailable. When using this option you can direct the thin client to the server location through either of the following ways:
· DHCP Server - Select the Get INI and Upgrade server details via DHCP check box. The DHCP server will direct the thin client (using DHCP options) to the server location where the INI files reside.
· Manually entered server address - Clear the Get INI and Upgrade server
details via DHCP check box and enter the INI Settings (INI Server URL, and optionally the Username and Password of the server, if selecting the Server
requires authentication check box).
• Use local INI files only - Use this option when you want to use only local INI files and do not want to use available INI files on the network.
TIP: INI files can be cached locally if using the EnableLocal and LocalCopy INI parameters; see Reference Guide: Wyse

"How to Set Up Automatic Configuration"
TIP: Wyse thin clients do not require device management software. They are configured to obtain their IP address, as well as the location of configuration instructions, from a DHCP server. However, you can use Wyse Device Manager (WDM) for a more hands-on management of your thin clients. For information about configuring your thin clients to
communicate with a WDM server, see "WDM" and related INI parameters in Reference
Guide: Wyse

Enhanced Ubuntu™ Linux INI Files.
How INI Files are Employed
INI files (created and maintained by the administrator) determine how the thin client is configured. The thin client accesses INI files from the server during the initialization process. Typically, INI files are accessed through FTP, HTTP, and HTTPS; if no protocol is specified, the default is anonymous FTP.
INI files are employed as follows:
• wlx.ini - This is the global INI file. One wlx.ini file is available to all users. It contains global parameters for all thin clients accessing the server. If the operating system cannot find wlx.ini, it defaults to wnos.ini.
• {username}.ini - This file is unique to each user. The {username}.ini file contains the connection profile for each user. Parameters in the user profile generally supersede the identically named global parameters.
• $MAC.ini - This file can be used for device-specific configuration. If the thin client locates this INI file (it is stored in the same directory as wlx.ini), wlx.ini is not accessed, unless you use the include=wlx.ini parameter.
When a thin client is initialized, it accesses the global wlx.ini file. When a user logs in, the thin client accesses the user’s unique {username}.ini file. For detailed information on constructing and using Wyse Enhanced Ubuntu Linux INI files, refer to Reference Guide:

TIP: If both PNLite and a user profile are being used, the username must be defined in the
Windows domain to be used, and the password must be the same for the domain and the profile.

How to Set Up Automatic Configuration
For a Wyse thin client running Wyse Enhanced Ubuntu Linux to successfully access INI files and configure itself from a server, you must set up the server with the correct folder structure (where the INI files and other files are located), direct the thin client to the server, and then reboot or start the thin client.
After DHCP and servers are configured and available, the thin client checks (at each boot up) to see whether or not any configuration changes are available on a predefined server
(DCHP Option #161 specifies the server URL, DCHP Option #162 specifies the root path to the server). If configuration changes are available, the changes are automatically installed.
Step 1: Prepare the Root Directory and Folder Structure on the Server
Set up the following folder structure on your server under the C:/inetpub/ftproot folder (for
FTP) or C:/inetpub/wwwroot folder (for HTTP or HTTPS) and place your INI files and other necessary files inside the structure as noted (this list describes the folder structure, starting with the root directory).
/wyse/ The root directory. It stores the wlx folder and the addons folder.
/wyse/wlx The main INI configuration folder. It stores the following:
• wlx.ini file or $MAC.ini file
• bitmap folder
• certs folder
• ini folder
/wyse/wlx/bitmap
/wyse/wlx/certs
/wyse/wlx/ini
/wyse/addons
The folder where you can place custom images you plan to use.
The folder where you can place the CA certificates that can be imported to a thin client.
Note: Use the Certs and ImportCerts INI parameters in the wlx.ini file to import the certificates to thin clients.
The folder where you can place the {username}.ini files.
The folder where you can place the add-ons you want to use.
It also stores the directory file and the *.deb packages available to be installed on the thin client. The directory file should list all available add-ons. The directory file is required in the addons folder to guarantee that add-ons are properly located.
NOTE: If you want to do an update with the Preserve changes option enabled, ensure that your addons folder includes a copy of your current add-ons. The system may require two reboots to fully update the add-ons while preserving local changes.

Be sure to create/activate the two required MIME Types (.ini and .) under IIS (on a per site basis) to enable downloading. Also be sure your Web server can identify the file types used by Wyse thin clients.
To create/activate the .ini MIME Type:
1. On your IIS server, use the File Types menu to add a New Type.
2. In the File Type dialog box, enter the Associated extension .ini and Content type
(MIME) text/plain.
3. Click OK to apply the settings.
To create/activate the . MIME Type:
1. On your IIS server, use the File Types menu to add a New Type.
2. In the File Type dialog box, enter the Associated extension . and Content type (MIME)
text/plain.
3. Click OK to apply the settings.
For detailed instructions on adding the .ini and . MIME Types, refer to Wyse Knowledge
Base Solution #21581 (go to the Wyse Knowledge Base at http://www.wyse.com/kb and search for 21581).

Step 2: Direct the Thin Client to the Server
After you set up the folder structure and populate it with the correct files, you must then direct the thin client to the location of the server by one of the following ways:
•
•
Manual direction (see "Manually Configuring the Server Location")
IMPORTANT: Using DHCP is strongly recommended.
Using DHCP
When using DHCP to direct the thin client to the location of the server (recommended), information about the server and root directory is obtained from the following DHCP options:
• 161 - The server.
• 162 - Root path to the server (ftp/http/https).
· If no root path is defined, /wyse is assumed.
· If a root path is defined, the additional path will be appended to the URL supplied by option 161.
• 184 - (Optional) Server username (to server specified in option 161).
• 185 - (Optional) Server password (to server specified in option 161).
TIP: Check-in for configuration changes is done early in the boot process. For that reason, changes in DHCP information may not be propagated to a unit until a full boot is completed. However, you can avoid this by forcing a renewing of the DHCP lease, which makes sure that the unit has the latest file-server location before the next check. Simply, right-click the Network Manager icon, click Enable Networking to disable it, right-click the Wireless Manager icon, and then click Enable Networking to enable it again (the
DHCP lease is renewed).
TIP: For general instructions on adding DHCP Options #161 and #162, refer to Wyse
Knowledge Base Solution #16132 (go to the Wyse Knowledge Base at http://www.wyse.com/kb and search for 16132).
Use the guidelines shown in Table 3 when creating and adding the DHCP options you
need.

Optional string. If this is an IP address or resolvable hostname, the protocol is assumed to be FTP; however, it may be the leading portion of a URL that specifies another protocol. If using the
URL form, it should not include a trailing slash
(for example, http://server.example.com or ftp://
192.168.0.1).
Optional string. The relative directory starting from the root directory must be given. For example, on an FTP server, the full directory may be C:/Inetpub/ftproot/wyse, where wyse is the directory that contains the INI files. In this example, the correct string value for this DHCP option is /wyse.
On a Linux server, an FTP user-based directory might be /home/test/wyse. In this example, if the FTP user is test, then the FTP root path is
/wyse and not the full path (/home/test/wyse).
This value should use URL path notation (start with a forward slash, /, and use a forward slash as folder separators).
Optional string. IP address or FQDN of the
PNLite server.
Optional string. DHCP equivalent of the
DomainList ini file parameter.
Optional string. Username to use when authenticating to the server specified in Option

Manually Configuring the Server Location
To manually configure the server location (not recommended), open the INI Settings dialog box (click System Settings icon and then click INI Settings), and enter the URL
(for HTTP or HTTPS; FTP URL is allowed for FTP) for the INI server in the INI Server
URL text box. For more information, see "INI (Source) Settings."
Step 3: Reboot the Thin Client
After you reboot (or start the thin client), the thin client will look in the defined root path for the latest available configuration changes if necessary. Additionally, it will check the
directory file in the addons folder to see if any changes for installed add-ons are defined.
Add-ons that exist in the addons folder but are not listed in the directory file, will be ignored during check-in.
