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 industrys 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. Introduction | 5 Echo allows you to update the thin clients 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. 6 | Introduction 2 2 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. Getting Started | 7 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 8 | Getting Started 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. Getting Started | 9 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. 10 | Getting Started 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. Echo Agent System Information Echo Management- Displays the current status and information of the Echo Management server to which your thin client is connected. Management Status-Displays when the thin client is being managed by an Echo server. Management Server-Displays the current address of the Echo server.

Hardware Model-Displays the name of the thin client in use. 12 | Getting Started 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 Take Snapshot in the Local Storage Settings section of the DeTOS control panel. In order to change or add connections, the changes must be pushed down by Echo. Getting Started| 13 3 3 System Settings Display Settings This section describes the display options available for a single monitor attached to a terminal. From the DeTOS desktop, select DeTOSControl Panel. Click the Display icon on the left-hand side of the Control Panel, under System Settings.

Be sure to reboot the terminal after you pressed this button. 16 | System Settings Management Management Server Configuration During bootup, if the thin client cannot make contact with a Management Server, then a white splash screen will appear just prior to the DeTOS desktop loading. This screen contains 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 Server Configuration screen allows you to configure the behavior of this splash screen, along with other management server options. From the DeTOS Desktop, select DeTOSControl Panel. Click the Management icon on the left-hand side of the Control Panel under System. Managed/Unmanaged-By default, the thin client is set to Managed mode and will attempt to make contact with a management server. You have the option of severing all communications with a management server by selecting the Unmanaged radio button. Press Apply and reboot the thin client for this to take effect. System Settings | 17 Server Address-While in managed mode, the thin client will maintain contact with a management server named ws-broker. Use this field to specify a different hostname or IP address for your management server. Splash Screen Timeout-Use this field to adjust the number of seconds the splash screen appears on the screen before it times-out and loads the DeTOS Desktop. Enter a value of 0 to bypass the screen altogether. Splash Screen Allow Cancel-A Cancel button is provided on the splash screen that allows the user to abort the timeout delay. Uncheck this box to hide the cancel button and force the user to wait the required amount of time. NOTE: The purpose of the splash screen feature is to gracefully handle network latency that may occur during the thin clients first contact with a management server during bootup.

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:
