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-
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-
protocols including Citric ICA Client, RDP, or VMware Horizon View.
Centrally Managed-
using Devon IT Echo Management Console.
Configuring a session out of the box is quick and painless using
DeTOS can connect to hosted desktops using the industry’s best
DeTOS-based terminals can be centrally managed
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.
Introduction | 5
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
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

default, DeTOS based terminals try to locate a management server. If a
management server is found, the terminal switches to managed mode, where it

standalone/unmanaged mode and use its local configuration.

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
DeTOS control panel. In order to change or add connections, the changes must
be pushed down by Echo.

Network Settings
By default, the thin client attempts to contact a DHCP server on your network
during bootup. If you have a DHCP server on your network, then the thin client
will acquire an IP address automatically and no further network configuration is
required on your part. However, there are additional options available.

Connections can be created on Ceptor units in two different ways. The primary
way is through the First Boot Wizard, which gives you the opportunity to set up
Citrix ICA, RDP, or VMware Horizon View connections that are accessible as
soon as the wizard is completed. Another way is to push them down to a unit
using the Echo Management Console. For more details on how to do this,
please consult the Echo Administration Guide.

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:
