Writing Your Own Driver
If you are using an operating system not supported by the Elo drivers described
above, contact Elo Technical Support for information on the availability of other
drivers. Technical manuals are also available on the touchscreen controllers with
machine-independent example code for writing your own drivers.
Touchscreens and Controllers Supported
Elo produces two touchscreen technologies: resistive and surface wave (SW). The
AccuTouch®resistive touchscreen consists of a glass panel molded to the precise
shape of a display's face. The glass is coated with a transparent, conductive layer
and then covered by a clear, hard-coated sheet of plastic. This cover sheet is
suspended over the glass by less than one-thousandth of an inch with tiny
separator dots. With a light touch, the conductive inner surface of the plastic sheet
makes contact with the underlying glass. The resulting voltage is digitized for
each axis and a coordinate determined.
The IntelliTouch®surface wave touchscreen consists of a clear glass overlay with
piezoelectric transducers and a set of reflector stripes. Surface waves are
transmitted by the transducers, reflected across the face of the overlay, and
reconverted into an electronic signal. A finger or gloved hand touching the

About Elo Software 5
touchscreen absorbs a portion of the wave at the touch location. The touchscreen
controller's microprocessor analyzes the resulting change in the received signal
and determines the touch coordinates. The IntelliTouch touchscreen can sense
both touch location and touch pressure.
A touchscreen controller is required for both technologies to provide touchscreen
drive signals, convert received analog signals into digital coordinates, and
transmit coordinates to the PC. There are several types of controllers.
Serial controllers use a standard RS-232 port and are baud rate selectable. They
can be mounted anywhere; for example, externally (in separate enclosures) or
inside display enclosures.
Bus controllers plug directly into a card slot within an IBM PC, PS/2, or
compatible computer, so external packaging and power is not required. Bus
controllers are address and interrupt (IRQ) selectable and are available for PC-Bus
(ISA/EISA) and Micro Channel architectures.
The software on the Elo DOS and Windows Driver Disk supports the Elo
touchscreen controllers listed below. E281{A}-4002 refers to both the E281-4002
and E281A-4002 controllers. Likewise, E281{A}-4025 refers to both the E281-
4025 and E281A-4025 controllers.

System Requirements
The DOS drivers will run on any system with DOS version 2.0 or later. The
Windows drivers will run on any system with Windows 3.1 or later. The DOS
demonstration program requires a VGA color display. The touchscreen calibration
program for DOS supports standard and VESA-compatible display modes.
Otherwise, all software is video independent. An Elo touchscreen must be
installed on the display and connected to a serial or bus controller.
Differences from Previous Versions
•The ELODEV and MonitorMouse for DOS/Windows disks and manuals have
been combined into this single manual and disk. A new installation program is
included. The installation program and Touchscreen Control Panel for
Windows are included in English, German, French, and Spanish.

This chapter describes the installation procedure for the software on the DOS and
Windows Driver Disk. Four steps are required:
Step 1 Configuring the touchscreen controller.
Step 2 Installing the controller.
Step 3 Running the INSTALL program.
Step 4 Calibrating the touchscreen.
STEP 1 - CONFIGURING THE TOUCHSCREEN CONTROLLER
Elo ships most touchscreen controllers preconfigured for use with Elo software.

10 Chapter 2 - Installation
•Serial controllers are usually ready to use.
•PC-Bus controllers require a hardware interrupt (IRQ) and a block of I/O ports
that will not contend with another device. If IRQ5 and/or I/O ports 280-299
are not available, you may have to re-jumper your controller.
•Micro Channel controllers are configured with the Reference Disk included
with your PS/2 or compatible computer.
Switch and jumper settings, as well as other configuration information, are given
in Appendix A.
STEP 2 - INSTALLING THE CONTROLLER
If you need help installing the controller or making the connections, see the
AccuTouch Product Manual or the IntelliTouch Product Manual as appropriate
for step-by-step instructions.
STEP 3 - RUNNING THE INSTALL PROGRAM
The DOS and Windows Driver Disk contains an installation program which
automatically transfers all necessary files to your hard disk.
If you will be installing the Windows drivers, be sure Windows is installed and
operating properly before proceeding. You must have a DOS mouse driver
(MOUSE.COM) installed for your mouse if you wish to continue using your
mouse along with the touchscreen in DOS or Windows.
If you only wish to change the configuration of your touchscreen controller, see
Changing Your Hardware Configuration with SETUP, page 14, for information
on the SETUP utility.
To install the software, insert the DOS and Windows Driver Disk and type:
A:INSTALL [Enter]
or B:INSTALL [Enter]
Respond to the on-screen prompts and instructions. You will be asked to specify
the model and configuration of your controller, then select between DOS Express
Installation, Windows Express Installation, or Selective
Installation. The software to be installed and disk space requirements will be
displayed for each installation option. You may specify the drive and directory for
the files you choose to install, or use the default (C:\TOUCH).

Step 3 - Running the INSTALL Program 11
Your AUTOEXEC.BAT file, (and SYSTEM.INI file for Windows install-ations),
will be modified by the INSTALL program. Copies of the original files will be
saved as AUTOEXEC.OLD and SYSTEM.OLD.
Command Line Flags
Several flags may be specified on the INSTALL command line.
To override the default system language used by INSTALL, specify the -L flag as
follows:
INSTALL -L<x>
Use -Lg or -Ld for German, -Ls for Spanish, -Lf for French, or -Le for English.
To override the path to C:\AUTOEXEC.BAT, use the -a flag as follows:
INSTALL -a<filename with path>
To skip the VGA graphics sign-on screen, enter:
INSTALL :
More than one flag may be specified, separated by spaces. Flags may be in upper
or lower case.
Updating Existing Drivers
If you are updating a previous version of the drivers, be sure to install and read the
DIFFER.* files. These files explain the differences from all previous versions.
The file extension corresponds to the version for which changes are listed. For
example, ELODIFF.16 lists the changes made from ELODEV version 1.5b to
version 1.6.
It is best to erase or overwrite any files from previous releases. All files are
generally compatible, but mixing files from different versions may cause
problems. If you are updating to a hard disk, specify the paths containing the
earlier version and the INSTALL program will overwrite the obsolete files.
NOTE
All files are now installed into a single directory (default is \TOUCH). You will
probably want to delete the old version of MonitorMouse for DOS which was
previously installed in a separate directory (typically \MONMOUSE). INSTALL
does not delete this directory.

STEP 4 - CALIBRATING THE TOUCHSCREEN
The final installation step is calibrating the touchscreen. Type "GO" when
instructed to begin the calibration sequence.
You will be prompted to touch three calibration points on the screen. Before you
do so, position yourself in front of the screen in normal sitting (or standing)
position, with normal height and reach.
Using your finger as accurately as possible, touch each of the three points as they
appear in the corners of the screen. The program responds with a beep as you lift
your finger from each point.
Calibration is performed in four common video modes: 80x25 text mode, CGA
320x200 graphics, VGA 320x200 graphics, and VGA 640x480. If your DOS
application runs in another video mode, see Chapter 4 for additional information
on ELOCALIB. If you are running Windows in another video mode such as super
VGA, see Chapter 6 for information on calibrating the touchscreen in Windows
with the Touchscreen Control Panel.
The numerical values for the calibration points for the last video mode are
displayed. X or Y axis inversion is normal.
If the calibration program does not respond to a touch, check the cabling, the
switch and/or jumper settings on the controller, and the configuration you selected
when installing the software. Run SETUP to change the configuration (see page
14). See Appendix B, page 93 for additional troubleshooting information.
Why Calibration is Necessary
The need for calibration is unique to the touchscreen. Unlike mouse or keyboard
applications where the cursor is part of the image, a touchscreen is a physical
overlay with an independent coordinate system. Only by knowing the position of
the image can the PC software convert touchscreen coordinates into image
coordinates.
Besides the differences among touchscreens and controllers, calibration also
compensates for the variation in video image among displays. The image is
affected by horizontal and vertical adjustments on the monitor and by the physical
mounting of the touchscreen.
Additional calibration complications include image blooming, where bright
colored images expand, and the "pin cushion" effect, which causes the corners of
the display to be stretched. Poor display linearity can cause similarly sized boxes
to be larger at the edges of the screen than they are in the middle, or vice versa.
