Introduction
What is DeTOS?
Devon IT Terminal Operating System (DeTOS) Dell Edition is an embedded
Thin Client Operating System designed to be simple, secure and centrally
manageable. DeTOS can be used to access hosted desktops using Microsoft
Remote Desktop Services, VMware View, Citrix XenApp or XenDesktop, web-
based applications, and more.
DeTOS Features
 Simple- Configuring a session out of the box is quick and painless using
the DeTOS intuitive web based control panel. The same control panel can
be used either locally from the thin client or remotely from the
management software.
 Modern- DeTOS can connect to hosted desktops using the industry’s best
protocols including PCoIP, Citric ICA Client, Citrix XenDesktop,
rDesktop (RDP) or Windows Terminal Services, and VMware View
Client. DeTOS also includes a built-in browser that allows accessing
web-based applications or kiosk usage.
 Centrally Managed- DeTOS-based terminals can be centrally managed
using Devon IT Echo Management Console Dell Edition.
Echo is shipped as a virtual appliance, so it is easy to set up.
Echo can automatically discover and inventory the thin clients on your
network.
Echo has the concept of a default profile. Using a default profile,
additional thin clients are automatically configured when you plug them
into your network.

Introduction | 7
Echo allows individual profiles for different users, including specific
Connections, Thin Client Settings, Passwords, and Customizable Desktop
Icons.
Echo allows you to update the thin client’s firmware. Updates can be
scheduled to happen outside of production hours, for example over the
weekend.
Echo allows you to remotely take control of thin clients (shadowing) to
help troubleshooting users’ issues.
DeTOS Installation
No installation is required for customers who have purchased DeTOS based thin
clients from Dell. Your thin client already contains a factory installed DeTOS
operating system. A USB re-flash utility is available if you need to reinstall the
operating system at any point in the future.
Visit support.dell.com to download the USB re-flash utility tool for reinstalling
the operating system for OptiPlex FX130 and OptiPlex FX170.

Getting Started
After the initial bootup, or when booting up after having selected the Reset to
Factory Settings , your thin client will display the DeTOS desktop and taskbar.
To get started, do the following:
 Check that your thin client is connected to the network.
 If you have set up a management server in your network, check that the
thin client was able to contact the management server and is in managed
mode.
 Create a desktop shortcut to allow thin client users to get connected to a
remote server. (See Chapter 5, “Connections,” for more information.)
To check the network connection status, click the DeTOS button and then select
Control Panel .

Getting Started | 9
Along the bottom of the Control Panel is a row of status messages. These
messages include the DeTOS build number, the terminal's current IP address,
and a Thin Client Management Connection Indicator.
DeTOS default factory setting is DHCP. If you have a DHCP server on your
network, the status bar should show the leased IP address. If you want the thin
client to use a fixed IP address please refer to this guide's network section. A
message of no ip address will appear if network connectivity is lost or was
never established in the first place. This may be related to a loose or faulty
network cable. It may also be an indication of DHCP issues. If you need to
troubleshoot a network issue, please refer to the network diagnostic section
below.
Along with the IP address, the Control Panel status section also shows you
whether your thin client is in managed or unmanaged (stand alone) mode. By
default, DeTOS based terminals try to locate a management server. If a
management server is found, the terminal switches to managed mode, where it
“pulls” its configuration from the management server. If not, it will stay in
standalone/unmanaged mode and use its local configuration.
The Control Panel status area also shows the OS build. This is a string based
on the DeTOS version and the build date, using the following format: 7.x.x
(YY.MM.DD)
Management Server Splash Screen
During bootup, if the terminal cannot make contact with a Management Server,
then a black splash screen will appear just prior to the DeTOS desktop loading.
This screen contains the Devon IT logo and displays a message saying,
Attempting to connect to Management Server . The splash
screen will be displayed until successful contact is made with a management
server, the cancel button is pressed, or the specified timeout (30 seconds by
default) is reached.

10 |Getting Started
The Management section, found under the Control Panel , allows you to
configure the behavior of this splash screen. Configuration options include:
 Setting the terminal to Managed or Unmanaged modes.
 Specifying a different management server address
 Adjusting the timeout value
 Enabling or disabling the splash screen Cancel button
Management Server Indicator
Once you are on the DeTOS Desktop, the Echo Agent running on your terminal
will continue to periodically contact a Management Server named ws-broker
on your local area network. When successful, the Management Server
Indicator box found along the bottom of the Control Panel will read Managed .
Otherwise, the icon will change to a red circle and the status will say
Unmanaged . In this case, verify that your management server is online and
accessible on your LAN. Also be sure to check your DNS server to verify that
an entry for ws-broker exists and points to the IP address of your
management server.
Control Panel
The Control Panel is the local tool for configuring Connection and System
settings on your thin client.
 Connection Settings - Your terminal has the ability to connect to remote
servers utilizing several types of protocols. The rDesktop client uses the
RDP protocol and allows you to connect to Microsoft Windows Terminal
Servers. The Citrix ICA client is used to establish connections to Citrix
Presentation and XenApp servers. The VMware View client allows you
to connect to a VMware View server, which in turn, provides the end-user
with their own virtual desktop session. Lastly, you may create a Firefox
web browser connection to surf the web. This can be used for several
purposes:
Connect to a web applications; e.g., a webmail server.
Connect to a connection broker web interface; e.g., Citrix XenDesktop.
Use the thin client as a Kiosk (select the Enable Kiosk Mode button under
the Kiosk Mode panel)

Getting Started | 11
 System Settings - These are the display, sound, keyboard, mouse, printer
and date/time configurations for your terminal. Also under the System
section is the ability to set an administrative password for the control panel
and change the local storage mode.
Network Tools
The toolbar along the top of the Control Panel window contains a button named
Network Tools . Clicking this button will open a separate, smaller window that
provides you with current network status and useful diagnostic programs.
Interface Status
Click the Interface Status tab along the top of the Network Tools window to
view the IP address that is currently assigned to this terminal. The MAC
Address for this machine is also reported on this screen.
Diagnostics
If you are experiencing difficulty connecting to servers on certain segments of
your LAN, then you may want to use the ping command to verify you are
reaching specific servers and/or gateways on the subnet in question. To use
ping:
1. Select the Diagnostics tab from the Network Tools window.
2. In the Host Address field, type in the IP address or website you want
to test against and then press the Ping button.
3. If there is an error in the delivery to the destination, the ping
command displays an error message. Otherwise, replies will
continuously display for each packet successfully sent and received.
4. Press the Stop button to terminate the ping loop.

12 |Getting Started
Launch Terminal
There may be times when you wish to open a Terminal window to run
command-line tools only accessible from a Linux shell. To access the shell,
click the button found at the top of the Control Panel named Launch
Terminal .
The ifconfig and ping commands are two popular Linux tools used for
diagnosing network connectivity and interface settings. The following two
sections describe their basic usage.

Getting Started | 13
Viewing Current Network Interface Settings
Type /sbin/ifconfig and press <Enter>to display the status of the currently
active network interfaces.
The value of inet addr , in the eth0 group of statistics, is the currently
assigned IP Address of your DeTOS terminal. If DHCP was used, this is the IP
address that your terminal acquired during bootup. If you configured static
network settings, then this address should match the value you entered in the IP
Address field.

14 |Getting Started
Export Config
If you are working with a Dell Support Analyst to troubleshoot a problem on
your terminal, you may be asked to send your terminal's Config file. You can
easily export your own Config file by following these steps:
Plug a USB flash drive into the terminal.
Click the button found along the top of the Control Panel named Export
Config .

Getting Started | 15
The process only takes a few seconds. Once it is finished you will receive a
message saying the export is finished and you may remove the flash
drive.
A
file named detosConfig .tar will now exist on the flash drive. This file
contains important diagnostic information that can be analyzed by Dell
Support and will help troubleshoot and solve issues you may be
experiencing

ELO Touch Screen Support
Upon connecting an ELO Touch Screen to your thin client you will be presented
with a calibration screen on first boot to ensure your unit functions properly.
There are two ways to calibrate your ELO Touch Screen device when attached
to your thin client.
Calibration –Option 1
Upon first boot of the operating system, you will see a gray calibration screen
with a countdown timer in the middle if an ELO device is found.
1 Use your finger or a stylus to tap the center of the red cross that displays
in the upper left-hand corner. Try to get as close as possible to the small
circle in the center of the red cross.
Another calibration spot will appear in the top right-hand corner. Use your
finger or a stylus to tap the center of the red cross. Repeat for the
calibration spots that appear in the bottom right-hand corner of the screen,
and then the bottom left-hand corner of the screen.
NOTE: If thecalibration is inaccurate, the calibration tool willask youto re-try
the process until a more accurate reading is achieved. You can wait until
calibration is achieved or press any key to cancelthe dialog at any time.

18 |Getting Started
You will see your normal desktop screen once the Touch Screen is calibrated.
Calibration –Option 2
The second method of calibrating the hardware can be found in the DeTOS
Start Menu . Select Calibrate Touchscreen . You will see the gray calibration
screen.
Follow the steps from Option 1 to calibrate the touch screen.
NOTE: There is currently no way toconfigurethe calibration of anindividual device and
push that setting via theDevon IT Echo Management ConsoleDell Edition software.
Calibrationfiles will not be persistent throughrebooting, sothe device must always have
to be calibrated when attempting to use a touchscreen devicewithDevon IT VDI Blaster
Dell Edition.
NOTE: Re-imaging or updating your thin client will require you to re-calibrate the
device.
NOTE: If at any time the calibration seems inaccurate you can plug in a mouse and
attempt to re-calibrate the device.

Persistence
Persistence, within the scope of thin client computing, refers to the continuing
existence of connections and settings after a terminal has been rebooted.
Default Behavior
By default, or after resetting your terminal to default factory setting, DeTOS is
set to persistent mode. This means that any configuration change you make will
persist across reboots. You can change this to a stateless mode where the thin
client settings and connections are dynamically “pulled” from the management
server, or a snapshot mode where you define the desired configuration and
prevent users from making any changes. These options are all configured in the
Control Panel , under the System Settings , in a section called Local Storage .
Persistence in DeTOS Thin Clients
There are two strategies for achieving persistence on DeTOS-based thin clients.
Strategy #1: Maintain Profiles via Remote Management Server
DeTOS thin clients can be centrally managed using the Devon IT Echo
Management Console Dell Edition. Using Echo, administrators can create
several connections and settings and then group them together to form one
single collection called a profile. This profile can then be pushed or assigned to
one or more thin clients. With your profile properly configured, each time a
terminal is booted up and discovered by Echo, all connections and system
settings according to its assigned profile are immediately applied –or pushed
out –to that terminal.

20 |Persistence
Strategy #2: Allow Configurations to be Stored Locally on the Thin
Client
The second approach for achieving persistence is to allocate a specific area of
the local DOM for reading and writing system settings and connections. DeTOS
allows for even greater flexibility by offering two variations of this strategy:
 Enable Local Storage- While running in this mode, DeTOS will write to
the local DOM each and every time configurations are added, deleted or
modified under the Control Panel.
 Enable Snapshot Storage- When this mode is selected, DeTOS allows
writes to the local DOM, but in a more finely controlled manner. An
administrator can configure the settings and then store the current
configurations to the DOM by clicking Take Snapshot . The only settings
and connections that will persist across reboots are the ones captured
during the snapshot. The terminal essentially falls back into a non-
persistent operating mode after the snapshot and discards any new
configurations from here on out –until the administrator clicks Take
Snapshot again, and a new snapshot is used as the primary configuration.
In some ways, this mode can be thought of as a hybrid of the standard
Enable Local Storage and No Local Storage modes.
Case Examples
The Local Storage section of the Control Panel allows you to use three
methods for local storage:
 No Local Storage
 Enable Local Storage
 Enable Snapshot Storage
These case examples are provided below to help you decide which of these three
options will work best for you.
