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
“pulls” its configuration from the management server. If not, it will stay in
standalone/unmanaged mode and use its local configuration.
