Elo TouchScreen Driver 5.X
Windows 8 32-bit and 64-bit Support.
Addition of 25-point (enhanced) calibration.
Added support for 2520 and 2521 controllers.
This user manual describes the installation of the touch-screen driver software and the
user selectable features of each screen. This manual refers to the software/driver that
are compatible with the Microsoft Windows operating systems including: Windows XP,
Windows Vista, Windows 7, and Windows 8. Drivers for both 32-bit and 64-bit versions of
these operating systems are included in the driver package and are automatically selected
based on OS type.
The drivers allow operation of the touch-screen over either USB or serial port. Some
touch-screens come with both USB and Serial options where either one can be used, but
not simultaneously. For each touch-screen, you must use either USB or serial connection
in order for touch to function. In addition, you can connect multiple touch-screens to
a system and each separate touch-screen can be connected through USB or serial. For example,
if you can have three touch-screens connected to the system, they can be configured in any
of the following ways:
Scrn1 Scrn2 Scrn3 USB USB USB USB USB Serial USB Serial USB USB Serial Serial Serial USB USB Serial USB Serial Serial Serial USB Serial Serial Serial
The installation process allows you to select which drivers, USB, serial or both,
that you want to install. Installing more drivers than you need is not a problem.
The driver package includes utilities which allow users to customize the operation
of their touch-screen in various ways. That information will be covered later in
this user manual.
Because there are many options to consider when installing the driver files, this section will cover the most common ways the driver can be installed. Please consult Elo Application Engineering for additional situations that are not covered in this section.

Silent Install and DOS Command Line Options
Silent Install feature is used to disburse a change/addition/deletion from a large network of touch screen monitors in one attempt without any action from the user.
The EloSetup program for this driver may be run as an attended or unattended program from a command line, batch file, etc. Silent Install is considered unattended mode because no user interaction is required. Attended mode requires user interaction during the installation process. Silent install is launched from the DOS prompt line
To Silent install for USB controllers use:
EloSetup /iu /sTo Silent install for a Serial controller on COM1 use:
EloSetup /is /P:1 /s /Precal
Enable PreCalibration allows the calibration data to be stored in the touch monitors. Touch monitors with pre-calibration data can be transferred to a different computer without the need to recalibrated on the other computer. PreCalibration feature must be enabled on the other computer in order for the driver to read the calibration from the touch monitor. System reboot may be required in order to get the pre-calibrated monitors to work correctly. Only 3-point calibration data can be stored in the touch monitor. The enhanced, 25-point calibration data cannot be stored in the touch monitor.
/Irpmoff: This feature applies to IR 4500 Serial controllers only. By default (at installation), it is enabled. This option sets the registry valueHKEY_CURRENT_USER\Software\EloTouchsystems\EnableIRPowerManagement to 0
/Reboot: With certain types of serial ports, a reboot of the computer may be required to complete the driver installation. In some cases, the installer will automatically detect this need and prompt for a reboot. In other cases you may need to use this option to force the installation to reboot the system after the serial driver gets installed.
To view all EloSetup options, run EloSetup as EloSetup /h.

3. Select the Elo Touchscreen driver open, then select Remove (Windows XP) or Uninstall (Windows 7 & 8). Elo Uninstaller will launch and proceed with removal of drivers from the computer.
Touch functionality can be disabled from the previously mentioned Advanced window. Follow the below steps to enable/disable touch functionality:
- Launch the Elo Touchscreen Control Panel.
- Select the Properties tab to the touch screen which you want touch disabled on.
- Click on the Advanced button.
- In the Options section, select to enable/disable the "Disable touch" option.
- Click Apply or OK to apply the change made.
- Repeat the above steps for each touch screen which you want touch disabled on.
Video Alignment (calibration) ensures that the mouse cursor appears at the position of touch.
Elo uses a three-point calibration sequence that accepts touch screens with any orientation of the X or Y-axis, whether its in landscape or portrait mode.
Once calibrated, the touch screen will be ready to use automatically each time the system is started.
When Video Alignment is selected, you will encounter the two screens below. Three target calibration points are used. When each target point is touched, it will move to a new target location. Once the screen is calibrated, the cursor should follow any new point on the touch screen.
The video alignment (calibration) program can be launched through the following scenarios:
During driver installation a check box can be selected to run the alignment program automatically after setup completes.
Through the Elo Touchscreen Control Panel application in the General tab by clicking the "Align" button.
Through the Elo Touchscreen Control Panel application in the Properties tab for the individual monitor and clicking the "Align"/"Re-Align" button.
From the Elo system tray in the Windows task bar by selecting the "Align" option in the contextual menu.
By running EloVa.exe directly from the Windows command line or \Windows\System32 directory.
By calling EloVa.exe directly from the installed application folder.
Running the Calibration ProgramWhen you run EloVA using one of the above options, touch each of the three targets as they appear on the screen.
You will then be asked to touch various points on the screen to verify that the cursor appears at the position touched. If the cursor appears at the position touched, click the green arrow to accept and exit out of the calibration program. If the cursor does not appear at the position touched, click the blue curved arrow and the calibration program will run again.
If you are using multiple monitors the alignment program will run on each individual monitor. If one of the monitors is not a touch monitor, Press the Esc key on the keyboard and the alignment program will advance to the next monitor. You can also wait until the program times out as indicated by completion of the progress bar.
Target Locations on the Screen
When a touch screen software is installed on an Elo monitor and the touch targets for calibration are not visible, target locations can be defined in an auxiliary file. Target locations for every monitor can be defined in a configuration file, EloTarget.conf. Contact Elo Application Engineering for availability and details on how to use this file.
Once the initialization has been complete, the user should touch the screen. As touch data is being collected, you should continue to touch the screen as instructed.
Follow the same procedure for all 3 targets as they appear.
Confirm the calibration by touching various locations on the screen and verifying that the cursor appears in the position touched. If the cursor appears at the position touched, click the green arrow to accept and exit out of the calibration program. If the cursor does not appear at the position touched, click the blue curved arrow and the calibration program will run again.
If you are using multiple monitors the calibration program will run on each individual monitor. If one of the monitors is not a touch monitor, Press the Esc key on the keyboard and the calibration program will advance to the next monitor, or wait until the program times out as indicated by completion of the progress bar.
Note: Acoustic Pulse Recognition (PulseTouch) is factory calibrated. Video alignment or calibration is not required.
EloVA can be run in either landscape or portrait mode.
Unusual Combinations of Expanded Desktop with Multiple Monitors
Unusual multiple monitor combinations may create an expanded Windows desktop that is not recognized by the default video resolutions built into the EloVA program. For this reason, an auxiliary file, EloVideo.txt, is available to supplement the defaults. If you are running an expanded desktop multiple monitor resolution that is not multiples of standard monitor resolutions, you may experience difficulties in calibrating all of your monitors properly. Contact Elo Applications Engineering for availability and details on how to use this file.
Enhanced Mode Calibration: 25-Point Calibration
In some rare cases, certain touchscreen types such as AccuTouch, even after applying the 3-point video alignment (calibration), linearity near the touchscreen’s edges will be less than desirable. If user feels this is a problem, the user may need to run the enhanced mode calibration: the 25-point calibration.
To run enhanced calibration, launch the Elo Touchscreen Control Panel application and select the “General” Tab. Select the “Enhanced” radio button and click Apply. If the touchscreen is not of AccuTouch touchscreen type, a prompt will be displayed stating that enhanced calibration will not improve the touch accuracy for those connected touchscreen(s).
To initiate calibration, click the “Align” button. Users can also initiate calibration by right-clicking on the system tray icon and selecting the “Align…” option. Once calibration is initiated, the user needs to touch each of the 25 targets firmly to complete the calibration process.
The 25-point calibration should be used for tocuhscreens with known touch performance issues along the screen's edges (for example AccuTouch); applying 25-point calibration to other types of touchscreens will not improve touch performance; in some cases, it may degrade touch performance.
The application name for 25-point calibration is EloVa25p.exe and is located in Elo Touch Solutions installation folder. The default installation path is: C:\Program Files\Elo Touch Solutions.
The configuration file “EloVa25.cfg” stores all parameters for the 25-point calibration. The user should not make any changes to the contents of this file.
All parameters specific to 25-point calibration are stored in the registry under the touch device’s Device Parameters/EMParams (EM stands for “Enhanced Mode”). If the standard 3-point calibration is performed on the same device again, the EMParams sub-key will be removed.
Control Panel (Elo Mouse Properties)
If there are multiple touch monitors connected then other monitors will also appear in the Elo Touchscreen Control Panel as Properties 1, Properties 2, etc.
The Elo Touchscreen Control Panel application allows configuration of the driver to suit the user's needs as well as to display system and diagnostic information to the user.
Each tab in the Elo Touchscreen Control Panel will be described in the following sections.
- The General tab is displayed when the Elo Touchscreen Control Panel is launched. The video calibration program, EloVa (Normal) for 3 point calibration or EloVa25p (Enhanced) for 25 point calibration, can be launch from this tab. The other tabs will be described in the proceeding sections.
- 25 point calibration (Enhanced mode) has the capability to achieve greater than 1% linearity.
- The Mode tab selects touch screen operating mode and enables you to configure touch functionality and desktop appearance. All selections made in the Mode tab will be activated after clicking the "Apply" button at the bottom of the window.
Mouse button emulation mode is selected by selecting the appropriate radio button. It functions as expected from a standard mouse. Draging and highlighting is supported in this mode. More information in the "Mouse Emulation (Drag and Double-click)" section below.
- Click on touch sends a touch command immediately(a mouse down/up message) at the point of touch on the touch screen. The user's finger must be removed from the touch screen before a new touch on the touch screen can be initiated. Tap and drag is NOT supported in this mode.
- Click on release sends (at the time of release) a mouse down/up message at the point where the screen was last touched. Dragging across objects on the screen will not highlight or select them unless the untouch occurs when the touch is over the object.
- Untouch timeout delay setting from 0 to 1200 seconds with the default being 10 seconds.
Mouse Emulation (Drag and Double-click)
Sends a "mouse down" message at the point of contact.
Selects an object if it was at the initial point of contact.
Drags a selected object on the screen.
Response to dragging is set by the "Drag delay" slider bar.
Sends a mouse up message at the point of untouch.
Double-clicks on an object when the screen is touched twice in rapid succession at the same location.
The speed to achieve double-click is identical to the speed of a successful double-click with the physical mouse.
Double-click speed is set from Mouse Properties in Windows Control Panel (Mouse Properties>Buttons>Double-click speed).
Double click area graphically sets the dimensions of the location around each clickable icon or object on the screen which will be recognized by Windows as a double-click. The size of the wire-frame square displayed in the Double click area tab is the actual size of double-click area accepted by Windows. The square can be increased or decreased in size by touching the appropriate arrows adjacent to the square. Note that the double-click box size is independent of screen resolution and must be defined for each user.
- Options allow various features of the desktop related to the touch screen to be configured. Each of the features selected will be activated after clicking the "Apply" button at the bottom of the tab.
Hide arrow mouse pointer turns off the standard mouse cursor.
Left-handed mouse interchanges the standard two-button mouse button assignments.
- Show tool tray utility activates the Elo system tray icon in the Windows Task Bar. See Tool Tray for a complete description of this feature.
Mouse Button Emulation Mode (PulseTouch)
The Mode options are the same for PulseTouch as noted above, with the exception of Click on Release, which is not supported for those type of touch screens.
The Sound tab sends a single-frequency tone or "Beep" to the system speaker and/or external speaker each time a valid touch occurs.
The beep is enabled by default when the driver is installed. It may be turned off by unchecking the Beep check box.
With Beep enabled, the user can decide whether the beep occurs as soon as touch is detected or after untouch is detected.
The Tone (frequency) and Duration of the beep can be adjusted by moving the appropriate slider in this tab. Tone and Duration is only enabled when Motherboard Beeper is enabled.
Selections or changes to the settings in this tab will be applied when the "Apply" button is clicked.
A Properties tab will be created for each touch screen controller installed by EloSetup and for each serial port reserved for a controller, even if that controller is not present. A number will be assigned to each Properties page that is related to the order in which controllers or ports are detected or enumerated. Each Properties page contains information extracted from the touch screen's controller and the system about the monitor, touch screen, controller and internal drive.
In the screen below
Properties 1, Properties 2 are the controllers installed.
- Windows monitor number lists the monitor that corresponds to the "Windows Monitor" from Windows Display Properties in the Windows Control Panel.
- Touchscreen Type lists the Elo touch screen used by its marketing name, i.e., AccuTouch for Elo's five-wire resistive touch screen
- Connection Port will indicate USB or Windows COM port (if Serial) depending how the touch screen is connection to the computer.
- Controller Model lists the marketing model number of the controller attached. It also lists the revision of the firmware loaded in the controller.
- Controller Status indicates whether the controller is "Working properly" or display any errors reported from the controller.
- Controller Serial Number displays the serial number of the connected controller.
The PulseTouch Properties tab is the same as other touch screens with the addition of additional screen information and the Set PulseTouch Preferences button which will allow you to dictate which usage type the PulseTouch monitor will be used for.
The buttons under screen information for any controller type will only appear after each touch screen has been calibrated.
Each Properties page also contains a Video Alignment section that has two functions:
The Identify Monitor button will display the Elo logo on the monitor associated with this Properties page for about one second each time this button is pressed.
The EloVA icon
will launch the video alignment program only for the monitor associated with the current Properties tab. Running EloVA from the Properties page avoids the need to align all monitors in a multiple monitor application when only a single monitor alignment is desired.
If a serial port is reserved for a touch screen controller that is not currently installed, the only Screen information displayed will be the number of the Windows COM port. No Screen configuration buttons will be displayed in this case.Each Properties page also contains an Advanced section to further configure each touch screen on a screen-by-screen basis.
Each Properties tab will include an Advanced button (as seen below). Clicking on the Advanced button will launch the Advanced Features window.
The Advanced window contains the following sections: Options, Right click on hold feature, Edge acceleration tool, and Right click are.
Disable Touch stops touch information from reaching Windows for the selected touch screen. Disabling touch has no effect on the operation of the standard mouse.
- Show right mouse button tool creates a mouse icon on the screen. Clicking on this icon allows the user to have right-handed mouse.
- Right Click on Hold allows a new and efficient way to create right clicks on the touch screen without the Right Mouse Button Tool. If the user touches the screen and continues to touch, a right click is generated on the screen as long as the user remains within the Right click area and after the Right click delay time-out has occurred. The right click delay allows the user to perform other touch screen operations normally. When the user touches the screen and holds his/her finger down, an animated clock is painted at the location and continues to tick and generate a right click at the location after its completion.
Enabling the Right click on hold check box will enable the feature for the current touch screen.
Enabling the Apply to all Touchscreens check box will apple the current values to all touch screens after the "Apply" or "Ok" button is clicked.
The Right click delay slide defines the right click delay value in milliseconds. The right click delay allows the user to perform other touch screen operations normally.
The Right Click Area section allows you to configure the area to generate a right click. This area allows the user the flexibility to touch within a larger area for a better experience.
NOTE: Right click on hold feature is enabled only in "Mouse emulation" touch mode. When Right click on hold feature is turned on, Drag Delay value is set to the minimum of 25 milliseconds.Right Click On Hold function is also not supported for PulseTouch touch screens.
- Edge Acceleration Tool launches the Cursor Edge Acceleration (CEA) utility for the selected monitor. In order to launch this utility, you much first enable the "Enable cursor edge acceleration" check box, then press the "Customize..." button. The CEA utility allows you to configure the cursor edge acceleration area, size, and speed to which the cursor will move to improve the experience in the "hard-to-reach" areas.
This tab will only appear for Carroll Touch (IR) screens (4000 and 4500).
It continuously monitors the health of the IR beams and reports any problems.
Enable blocked beam monitoring allows you to enable or disable beam health monitoring.
Enabling the Log failure message to file check box will write any future beam failure messages to a file "C:\EloDiags.log"
The Failed beam count before reporting failure option allows you to enter the minimum number of failed beams before you get a failure notification.
The Duration time for failed beam message option allows you to enter the number of seconds that the failure notification window will be displayed on the screen. The message will repeat again if the problem is not corrected.
The Beam test rate option allows you to modify the beam test rate from a slider bar. The beam test rate range is from 10 seconds to 2 minutes.
This tab only appears for Carroll Touch (IR) screens that have a separate built in beeper. This feature can be used to provide audio feedback of touches in cases where the screen is placed at some distance from the host computer. Use this tab to configure the sound characteristics of the beeper similar to the "Sound" tab in the main page.
The Beep monitor speaker on touch check box allows you to enable/disable the internal beeper.
The Tone slider allows you to adjust the tone of the internal beeper.
The Duration slider allows you to adjust the duration of the internal beeper.
Pressing on the Touch here to test beep sound area button allows you to test the current settings without changing focus away from the Elo Touchscreen Control Panel. Click the Apply button for any changes to be applied..
This tab will only appear for Surface Capacitive Touch screens (5020)
