# Installing the Driver

## Hardware

Touchscreen controllers must be configured for the driver prior to installation. Elo typically ships controllers in a default setup that is compatible with this driver. Controller requirements are:

### Serial

- Serial controllers must conform to these minimum requirements:
  - Baud rate-9600 baud.
  - Data format-SMARTSET
  - It is desirable for a full handshaking connection to be established between the touchscreen controller and the computer, but it is not required. The controller will function with this driver in a "two-wire", Receive Data and Ground (RxD and Gnd) configuration. The consequences of a two-wire connection are:
    - Automatic detection of the controllers on serial ports during setup is not possible
    - Controller information will not be registered in the Property Page of the Control Panel

### USB

- USB controllers require no configuration prior to installation.
- Elo's USB controllers are Human Interface Device (HID) compliant. The Windows XP and Windows Vista operating systems have native HID drivers that provide low-level support for Elo touchscreen controllers. An Elo touchmonitor with a USB touchscreen controller installed will provide the following limited operation with these native HID drivers. Operation of the controller will be limited without the installation of the software discussed in the next section:
  - The mouse cursor will move on the display in response to touch
  - The direction of motion on the display will depend on the orientation of the touchscreen and the defaults programmed into the controller and the driver
  - No "beep" will be heard when the screen is touched
  - No Control Panel application is available to configure the operation of the driver.

### Software

There are many options to consider when installing the driver files. This section will explain the most common ways that the driver is installed. Consult Elo Applications Engineering for situations not covered in this section.

> #### Setup from Windows Desktop

Single monitor, serial controller

- Run the self-extracting zip file to unzip the files, using the Run EloSetup option
- EloSetup will launch.
- Select the language for the Universal driver package.

> This language is used for all Elo components in future on the system. To change the user language you must install the package again on the system. Default selection from the dropdown uses the current users input language from the Windows subsystem.

- Currently the languages supported are English, French, German, Spanish, Italian, Japanese, Simplified Chinese and Traditional Chinese.

- Check the Install Serial Touchscreen Drivers box.

- Enable PreCalibration, this allows the calibration data (done in Normal 3-point mode) be stored in the touch monitors. Default selection is Disabled. Touch monitors with pre-calibration data can be used on system with pre-installed touch driver. System reboot may be required in order to get the pre-calibration monitors to work correctly.

- Review and accept the License Agreement

- Check Auto-detect Elo devices if your touchmonitor serial cable is connected to the computer and the serial cable supports hardware handshaking. If you connect the serial cable later, do not check the auto-detect box. Click the Next button.

- A list of all the serial ports that the system detected is shown. If you checked the auto-detect box in the previous screen, and your touchmonitor serial cable is attached to the computer, the COM port that you selected should be checked in the list. If this is the case, click Next and proceed to the next screen.

- The COM port you selected will be shown in the window of this screen. This is your last opportunity to change your COM port selection before the driver files are installed. Use the Back button(s) to change any of the selections you previously made. Click Next to complete the installation of the driver files.

- Depending on the revision of the driver you are installing, Windows may advise you that the "software you are installing has not passed Windows logo testing" . Select Continue Anyway to proceed with the installation. This message can be suppressed in future installations by changing the selection in Driver Signing Options. From the Control Panel>System>Hardware>Device Manager>Driver Signing.

- When the Setup Complete screen appears, you may choose to run calibration the (Elo Video Alignment program, EloVA) immediately or wait until later. If you choose not to run this program now, you can run it from the Elo Control Panel application.

> Single monitor, USB controller

> 1. Run the self-extracting zip file to unzip the files, using the Run EloSetup option.

> 2. EloSetup will launch. Select the language for the Universal driver package.

> 3. Check the Install USB Touchscreen Drivers box.
