Introduction
What is DeTOS?
Devon IT Terminal Operating System (DeTOS) 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 Horizon 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 Citric ICA Client, RDP, or VMware Horizon View.
Centrally Managed-
DeTOS-based terminals can be centrally managed
using Devon IT Echo Management Console.
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.
Echo allows individual profiles for different users, including specific
Connections, Thin Client Settings, Passwords, and Customizable Desktop
Icons.
6 | Introduction
Echo allows you to update the thin client’s embedded OS. Updates can be
scheduled to happen outside of production hours, for example over the
weekend.
DeTOS Installation
No installation is required for customers who have purchased DeTOS based thin
clients from Devon IT. 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.
First Boot Wizard
The first time your terminal boots up, you will be taken through a first boot
wizard. This wizard can help you to configure a variety of settings in order to
better utilize your terminal. It is advised that you are familiar with the material
in this guide as well as the Echo Administration Guide to best utilize the first
boot wizard.
.
Getting Started | 7

Getting Started
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 6, “Connections,” for more information.)
To check the network connection status, click the
DeTOS
button and then select
Control Panel
.
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.
8 | Getting Started
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.
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
Getting Started | 9
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 RDP 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 Horizon View client
allows you to connect to a VMware Horizon View server, which in turn,
provides the end-user with their own virtual desktop session.
System Settings -
These are the display, sound, keyboard, mouse, 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.
10 | Getting Started
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.
Getting Started | 11
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.

Persistence
Persistence, within the scope of thin client computing, refers to the continuing
existence of connections and settings after a terminal has been rebooted.
Upon completion of the first boot wizard, a snapshot of the thin client is taken
and saved in a data partition for basic settings. All of the connections, settings,
and network settings assigned during the first boot wizard will be saved to the
Echo server once this snapshot is taken and they will persist and carry over after
a reboot.
After this point, only changes made to your Network Settings will persist if
changed through the DeTOS control panel. In order to alter your settings after
this point, either the changes will have to be applied through the Echo console,
or you must click

Troubleshooting Tips for VMware Horizon View Connection
If you set your session to full screen but the display covers only a fraction
of the entire screen, then your allocated RAM for the virtual desktop may
need to be set a little higher.
If certain features like foreign keymaps, CD-ROM, OR USB stick are not
passing through to the virtual desktop session, check if your VM is at the
correct version. You can download the latest agent software executables
at VMware's website at: http://www.vmware.com/downloads.
If you plan to use USB flash drives within your session, it is best to use
sticks formatted in FAT or NTFS. Long delays sometimes occur when
using flash drives formatted in FAT32. Other USB troubleshooting tips
can be found at the following VMware site:
