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.

For service, visit http://www.wyse.com/support/authorized-service-centers.

WARNING: There is a risk of explosion if the battery is replaced by an incorrect type. Always dispose of used

batteries according to the instructions accompanying the battery.

Perchlorate Materials - Special Handling May Be Required under California Code of Regulations, title 22. (Only

required within the U.S.A.)

Getting Started: Quickly Learning

the Basics

Use the following information to quickly learn the basics and get started using your thin

client:

•

"Logging In"

"Using Your Home Screen"

"Configuring Thin Client Settings and Connections"

"Connecting to Network and Session Services"

"Connecting to a Printer"

"Connecting to a Monitor"

"Locking, Logging Out, Shutting Down, Restarting, and Suspending"

"Additional Getting Started Details"

TIP: While it can be used in environments without central configuration for basic

connectivity needs, Wyse Enhanced Ubuntu Linux is designed to be centrally managed

and configured using INI files. In general, it is recommended that you use central

configuration to enable you to automatically push any desired default configuration to all

supported thin clients in your environment (see "Central Configuration: Automating

Configurations").

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

Connections").

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.

Central Configuration: Automating

Configurations

This appendix describes how to set up your environment to provide your thin clients

running Wyse Enhanced Ubuntu Linux with automatic configurations in three simple

steps.

It includes:

•

"How INI Files are Employed"

"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:

Wyse Enhanced Ubuntu™ Linux INI Files.

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

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.

/wyse/wlx/ini

The folder where you can place the {username}.ini files.

/wyse/addons

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.

Central Configuration: Automating Configurations

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:

•

DHCP (see "Using DHCP")

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 T a ble 3 when creating and adding the DHCP options you

need.

161

Server (ftp/http/https)

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).

162

Root path to the server Optional string. The relative directory starting

(ftp/http/https)

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).

Wyse Device Manager Optional binary IP address or FQDN of the WDM

(WDM)

server. This option can specify up to one Wyse

Device Manager server.

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.
