Introduction
What is DeTOS?
Acer 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 View, Citrix XenApp or
XenDesktop, web-based applications, and more.
DeTOS Features
Simple-
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-
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-
managed using Acer Echo Management Console.
Configuring a session out of the box is quick and painless
DeTOS can connect to hosted desktops using the
DeTOS-based terminals can be centrally
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.
6 | Introduction
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 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 Acer. 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.

to download the USB re-flash utility
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.

a Devon Zero™ client, or as a thin client console running DeTOS. If
running in Devon Zero™ mode, see the section titled “Devon Zero™” in
the “Advanced Options” chapter to continue. If you chose to operate
your thin client using DeTOS instead, you will be shown 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 6, “Connections,” for
more information.)
To check the network connection status, click the

Along the bottom of the

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 Acer 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.

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
Panel
, under the
System Settings
, in a section called
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 Acer Echo
Management Console. 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.

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 (disk) for reading and writing system settings and
connections. DeTOS allows for even greater flexibility by offering two
variations of this strategy:
Enable Local Storage-
write to the local DOM each and every time configurations are
added, deleted or modified under the Control Panel.
Enable Snapshot Storage-
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
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
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.
While running in this mode, DeTOS will

These case examples are provided below to help you decide which of
these three options will work best for you.

Case 1:
NOTE: If you would like to change your configuration later, you will
have to press the
Take Snapshot
button again to save all of the
changes made to your terminal. Upon reboot, your terminal will load
whichever Snapshot was is currently being used. Pressing the
Clear
Local Storage
button will ask the terminal to clear all connections and
settings saved locally, clear the current snapshot used for the reboot,
and restore itself to factory settings on the next reboot.
“I do not want any users to mess up the thin client’s
configuration. I am currently using, or plan to use, Acer Echo
Management Console to centrally manage my thin client.”
Solution:
the
You will be utilizing strategy #1, as described earlier. Choose
No Local Storage
option on the thin client and make sure you have
an Echo server properly configured and accessible on your LAN. With
persistence disabled, the thin client becomes stateless and relies
completely on the management server for all its configurations.
Case 2:
“I simply want the thin client to maintain its configuration
settings locally. I do not want to rely on a management server.”
Solution:
Choose the
Enable Local Storage
radio button option. While
running in this mode, DeTOS will write to the local DOM (disk) each and
every time configurations are added, deleted, or modified. A remote
management server is not needed.
Case 3:
“I like the idea of having a non-persistent terminal with an
assigned profile, but do not want to use Acer Echo Management Console
to manage my terminals. What's the alternative?”
