OPERATING THE DEVICE

ENGLISH

Before using the device

Prior to using the device it is necessary to connect the power adapter.

Connect the power cable to the power adapter.

Connect the power cable plug from the power adapter to the power connector on the back part of the de­vice.

Plug the power cable into the electrical power outlet (220V, 50 Hz).

Note: Before switching on the TDC-5000 PC it is a good idea to look over the sections devoted to meth-

ods of controlling the device.

Switching on

After connecting to the power source press the POWER button on the side of the device. The device switches
on, as indicated by the green LED on the front of the screen. After performance of a quick system test, the
operating system is launched.

If you have a version of the device without a pre-installed operating system, it is first necessary to install it – see
the documentation for the relevant operating system.

Logging on to the operating system

The welcome screen of the operating system differs according to the type and version. Depending on the
type of operating system it is possible that your operating system will request the entry of a user name and
password for the user account.

Enter the required information for logging on to the user account and press Enter or click the relevant button
for logging on. If you are creating your own user account with a password, please remember the password,
as without it you will not be able to log on to your account.

Note: With the OS Linux CentOS 5.5 an user account is pre-set, username: elcom, password: elcom (root

has the password elcom123).

Note: With the OS Linux CentOS 5.5. if a screen saver launches and the system is set to request a

password upon returning to the operating system, it is necessary to enter the password using the
keyboard. It is not possible to enter a password through the touch panel.

Note: If during logon procedure the computer does not respond to the touch panel controls, connect an

external keyboard and mouse, which will allow you to log on and subsequently calibrate the touch
panel according to the process described in the section “Calibrating the touch panel“.

Switching off

The device can be switched off according to the standard procedure of the operating system or by pressing
the POWER button (OS Windows, Linux).

Restarting

Restarting the device is possible according to the standard procedure in the operating system being used.

If an emergency restart of the device is needed, press the RESET button. With this method of restarting you
risk losing any unsaved data of the applications which were open at the time of restarting. This solution should
be therefore used only if the operating system stops responding and it is not possible to restart it using the
standard method.

38

Operating the device

ENGLISH

Controlling

It is possible to attach a standard computer mouse or keyboard to the TDC-5000 PC through a USB port (or
a RS-232 in case of mouse). The mouse can be used to control the mouse cursor when using the operating
system. You can use the keyboard when entering text and controlling some elements of the operating system
and applications using keyboard shortcuts. The settings for the mouse and keyboard can be changed in the
system settings for the operating system.

An alternative method of control is by using the touch panel, which can be used to perform many operations
without using keyboard and mouse. The information you need to use the touch panel correctly is presented
in the following section.

Note: The way of controlling with the keyboard, mouse and touch panel may be different according to

the type of operating system used and its settings.

Controlling with the touch panel

The TDC-5000 PC is equipped with a resistive touch panel which allows you to control the mouse cursor or
enter text using the virtual keyboard on the display. The touch panel can be controlled by the touch of a finger
or using a special touch pen (stylus). If you use a keyboard or mouse and at the same time the touch panel
to control the computer, the individual methods of controlling will impact each other. Before using the touch
panel for controlling it is necessar y to calibrate the touch panel; the procedure is described in the section
“Calibrating the touch panel“.

Notice: Control the touch panel by gentle pressure of the finger or stylus. Do not use excess pressure

or objects with hard and sharp edges for controlling; otherwise you may cause damage to the
touch panel or the display.

Figure 3.1. Controlling the TDC-5000 PC by touching the screen with a finger

Controlling the mouse cursor with the touch panel

Using the touch panel you can control the mouse functions as follows:

Tapping on the screen is the equivalent of left-clicking the mouse – the cursor is shifted to the place of the
touch and the object beneath the cursor is selected.

Double-tapping – is the equivalent of double-clicking the left mouse button.

39

Operating the device

ENGLISH

Placing and holding a finger on one spot of the display – is the equivalent of clicking the right mouse
button, calling up the context menu. After the menu is displayed, tap on the desired item in the menu while
the relevant item is activated (this feature may not be available with the OS Linux system). Furthermore, with
the OS Linux, during shifting in some menus you cannot lift your finger when shifting between items, but
slowly shift the finger along the surface of the touch panel to the item you wish to select, where you can lift
the finger thus activating the item.

Note: Parameters for controlling the mouse cursor can be changed in the dialogue box for setting the

touch panel display on the “Setting“ card.

Entering text using the touch panel

By using an application that shows a virtual keyboard on the display it is possible to enter text by tapping on the
virtual buttons depicted. The choice of individual keys is most comfortably handled with the help of the touch
panel, but this can also be done using a mouse. Most modern operating systems include a virtual keyboard
as a standard component.

The virtual keyboard which is a standard component of the operating system is called us as follows:

Windows: Start � All programs � Accessories � Ease of Access � On-screen keyboard

Use: Place the cursor on the text field where you want to enter text, then tap the requested symbol on the
virtual keyboard.

Linux CentOS: you can use the application xvkbd, launched from the command line with the command “xvkbd”

Use: Tap on the button “Focus” in the upper right corner of the window of the virtual keyboard. The button turns
green and you can click on the text field where you want to enter text. By tapping on the virtual keyboard you
will enter the selected symbol so long as you do not select another window by pressing the button “Focus”,
or do not close the window to which you want to enter the symbol.

You can also search for and install other applications for a virtual keyboard for the operation system used
which will better suit your needs.

Calibrating the touch panel

For ensuring proper functioning and exactness of control using the touch panel, it is necessary to calibrate
the touch panel prior to use under normal operating conditions.

Note: Check the setting of the display and perform calibration of the display also in the case that control-

ling by touch is handled in a non-standard way (does not respond, is inexact, etc.)

Get to the dialog window for calibration of the touch panel through:

Windows: Start � All programs � TouchKit Configure Utility

Linux CentOS: System � Administration � Touchpanel calibrationn

A window is opened with tabs containing possible settings. Select the “Tools” tab with choices according to
Fig. 3.2. We recommend performing linearization of the display.

4-Point Calibration

During calibration, a cross with a circle is gradually displayed in each corner of the monitor. For proper cali­bration it is necessary to press and hold the center of the symbol until the blue color disappears. In this way
you ensure the setting of the exact value for pressing a point on the display.

Figure 3.3. Arrangement of calibration points with 4-point calibration

Clear and Calibrate

With this command all currently set parameters for the touch panel are deleted and a 4-point calibration is
subsequently performed.

Linearization

This is calibration of 9 or 25 points which are uniformly arranged on the touch panel. By performing lineariza­tion you achieve higher exactness and linearity of the touch panel. The procedure for linearization is similar
to that of 4-point calibration.

Connecting and disconnecting a USB device

When connecting any equipment to the TDC-5000 PC observe the manufacturer’s instructions for the given
device. After connection of a USB device to a TDC-5000 PC port, the operating system detects it and if it
has a driver available for the device, it will install the driver and the device can then be used. If a driver is
not automatically available, it is necessary to search for one and install it. Drivers are usually located on the
CD supplied with the device for which they are designated or can be downloaded from the Web site of the
manufacturer.

If after connecting and using a USB device you want to disconnect, it is a good idea to remove it safely – first
in the operation system (in order that all device operations be completed) and then after notification of the
operation system to physically pull out the relevant connector. The procedure for safe removal of a device
depends on the operating system used. Connecting and disconnecting USB devices when the TDC-5000
PC is switched off is always safe.

Note: Not all equipment allows for safe removal of hardware. Safe removal makes sense mainly with

equipment which stores data (hard disks, USB memory sticks) and which also use the write buffer.
Equipment which is not shown on the list of equipment that can be safely removed can be discon­nected without the procedure for safe removal.
