Introducing Touchscreens

Touchscreens are the ultimate operator/machine interface. In a touchscreen
system, you touch what you see. The computer responds. The human action and
the computer's reaction is simple, direct, and natural. Using touchscreens,
workers can control complicated processes. People who have never used a
computer before can interact easily with a touchscreen-based system.
Touchscreens bring the power of the computer within reach—in airports,
factories, shopping malls, schools, and hospitals.

Because of its many unique features, the AccuTouch touchscreen is ideally
suited for retail and restaurant point-of-sale, medical, instrumentation, and
process control applications. In fact, the AccuTouch touchscreen is used in
more applications than any other touchscreen.

Driver Software

Elo driver software provides a consistent software interface among all Elo
touchscreens and controllers.

The driver software scales the absolute coordinates received from the
touchscreen controller into translated screen coordinates, using the calibration
points obtained with the video alignment program included with the driver
software. The driver also performs other operations as directed by the
application.

Elo provides driver programs for the DOS, Windows 3.1, Windows CE,
Windows 95/98, Windows NT, Windows 2000, Windows XP, OS/2, and
Macintosh operating systems. Additional drivers are also available. Additional
operating systems are supported through outside sources. Refer to the Elo web
site, www.elotouch.com, for details.

If you cannot use an available driver, Elo can supply all the touchscreen related
information you will need to write your own driver for any type of system,
including UNIX workstations, real-time systems, and embedded systems. For
the 2500S controller, the SmartSet™ Touchscreen Controller Family Technical
Reference Manual which is available on the Elo web site, provide information
on this process. Machine-independent source code is included on a companion
disk and web site, www.elotouch.com.

Shipping Damage

If you notice damage to the shipping carton, or concealed damage, be sure to
save all packing materials for later inspection by the carrier, who is responsible
for any shipping damage.

If failure occurs during the warranty period, see the Limited Warranty section at
the beginning of this manual for instructions.

Touchmonitor Configurations

This chapter assumes you have one of the following:

• A touchmonitor with an internal 2210 serial controller.

• A touchmonitor with an internal 3000U USB controller.

• A touchmonitor with one of the following external controllers:

• 2210MX serial controller.

• 2201 PC-Bus controller.

Touchmonitors with an internal serial controller typically have a DB9 female
RS-232 connector on the back of the touchmonitor. A serial cable connects
directly from the back of the touchmonitor to the serial port on the computer.

Touchmonitors with an internal USB controller will have a USB cable exiting
the back of the touchmonitor. The USB cable connects directly to a USB port on
the computer.

The 2210MX serial controller is typically mounted on the back of the display
and uses either a keyboard power tap or external power supply. The serial cable
attached to the controller enclosure connects to the serial port on your computer.

PC-Bus controllers plug directly into a slot in your computer and do no t require
a special enclosure or power supply. A cable connects directly from the back of
the touchmonitor to the PC-Bus controller.

Controller boards, cables, and power supplies may also be ordered separately.

Touchmonitor Connections

Connecting the Power and Video

If you do not have a touchscreen installed in your display, skip to Chapter 4,
which details the installation of touchscreen and controller components.

The video display function of the touchmonitor and the touchscreen installed on
the monitor are entirely separate systems. You should first connect and test your
touchmonitor as a video display only. Follow the instructions provided by the
monitor manufacturer.

Install the Controller in Your PC and Connect the Touchmonitor

Complete these steps:

1 Discharge any static charge on your body by touching the back o f the

computer cabinet.

2 Note the Base I/O Port for use with the driver software. Factory default

settings are 280 (hexadecimal) and no interrupt. (The driver software selects
the interrupt.)

3 Turn the computer off and unplug the AC power cord from the outlet.
4 Remove the computer's cover. Refer to the computer user's manual for

instructions.

5 Choose an available expansion slot.
6 Remove the screw holding the expansion slot's access bracket, then remove

the bracket.

7 Insert the touchscreen controller into the expansion slot. The controller

should seat fully into the slot and the access bracket should mate with the
frame of the computer.

8 Replace the access bracket retaining screw, insuring that the controller

remains seated in the socket.

9 Replace the computer's cover.
10Plug the DB9 female end of the supplied touchscreen cable into the DB9

male connector labeled "Touchscreen Interface" on the back of the
touchmonitor case. Plug the DB9 male end of the touchscreen cable to the
DB9 female connector on the controller.

11Plug the AC power cord back into the outlet and reboot the computer.

Touchscreen Application Tips

Sometimes a simple change to your application may mean the difference
between success and failure.

1 Windows applications should be run full screen-don’t display a title bar or

menu bar in kiosk applications.

2 Bright background colors (no black!) in your application will hide

fingerprints and reduce glare. Dithering or other patterned backgrounds, such
as a crumbled paper look, will help the eye focus on the screen image instead
of reflections, even in areas with no icons or menu choices.

3 Use a simple point-and click interface with large buttons. Do not use

dragging, double-clicks, scroll bars, drop-down menus, multiple windows, or

other elements that can confuse the user and interfere with usability and
efficiency.

4 Turn the cursor off—your user will focus on the entire screen instead of the

arrow. A cursor on the screen makes the user subconsciously think, “How do
I get the arrow to do what I want?” Remove the cursor, and the user’s
thinking and action will be direct instead of indirect, unlocking the true
power of touchscreens.

5 Always give your users feedback as soon as they touch the screen. A 3-D

button effect (similar to a Windows standard button) works well. Output a
“click” or other sound whenever they touch the screen. Also, be sure that the
display clears immediately and displays an hourglass while loading the next
screen. Immediate feedback is critical to reassure users that their touch is
registered.

6 Make your application run fast. Users will walk away from a sluggish

system, but you can keep their attention with a quick response to touches.
Speedy systems also reduce vandalism. (Graphics modes with excessive
colors or resolution only slow down your system, Using 256 colors is
typically more important than resolution above 640 x 480.)

7 Try to make the application intuitive; limit choices; and guide the user as

much as possible. Testing your application on focus groups will disclose the
areas that need improvement. If anyone pauses in confusion for even a
moment, think how to improve the application.

8 Digitized speech via a sound card can walk users through your application.

For example, “Touch the first letter of the company you are looking for.”
Click. “Now touch OK.” There is something almost magical about a user
interface with voice prompting and touch response. Your brain can
simultaneously process voice while absorbing image.

9 Animation and large fonts help attract users to kiosk applications. The kiosk

design (cabinet) should also be attractive.

10When designing a kiosk cabinet, consider the following. If using forced air

ventilation, put your fan at the top, near the monitor’s vents. Keep the intake
away from the floor and airborne dust from footsteps. Keep air from entering
around the CRT face, too. The kiosk design should accommodate variation in
monitor dimensions and bezels, as monitor models may come and go every
few months. Remember to point your speakers in the direction of the user’s
ears. Finally, choose a finish that does not show fingerprints—avoid polished
stainless steel, chrome, or glossy black paint.

OMPONENT INSTALLATION

Elo purchases and resells a variety of monitors, called touchmonitors, with
touchscreens and all related components fully installed. If you already have a
touchmonitor, follow the installation instructions in Chapter 3.

If you do not have a touchmonitor, read this chapter for details on installing
touchscreen components that will convert your monitor into a touchmonitor.
Details are given on mounting the touchscreen, controller, and connecting
cables. While this chapter refers primarily to CRT-based monitor technologies,
much of this information can be applied to other monitor technologies. See “Flat
Panel Display Integration” on page 4-59.

These instructions assume you have purchased an Elo touchscreen installation
kit (P/N 458095-000), and a transient protection cable (PN 899389-000). Only a
minimum of equipment and materials is required beyond what is provided in the
kits.

In brief, adhesive materials are used to fasten the touchscreen to the CRT and
then the assembly is reinstalled in the original enclosure with minor
modifications. If this procedure is not suitable for mechanical, electrical, or
optical reasons, there are other techniques for touchscreen installation that may
achieve the desired results. These techniques often require specialized
equipment or materials, and a complete discussion is beyond the scope of this
manual. See “Installing the Touchscreen” on page 4-40.

Safety Information

WARNING:

The touchscreen installation procedure outlined in this chapter may require expo­sure to high-voltage components and handling of the CRT. This procedure can be
dangerous and an accident is potentially lethal. Therefore, the procedure should
only be performed by a qualified person. Read this entire chapter before attempt­ing a touchscreen installation. Follow the procedure carefully, w ork with the power
off and the unit unplugged, observe all warnings, and wear pr otective c lothing . Elo
is not liable for damage or injury that could result from your actions.

Consider purchasing a touchmonitor from Elo if you do not have previous
experience working with touchscreens and disassembling monitors. Elo also
offers touchscreen installation services for customers specified monitor.

Work Area

Before proceeding with the installation, prepare a padded work surface. A
plastic waste basket is recommended for supporting the CRT during part of the
installation.

Protective Clothing

Wear safety glasses, gloves, a rubber apron, and heavy protective clothing for
any portion of this procedure that involves handling or working near the CRT.

Getting Started

AccuTouch touchscreens can be installed on most types of monitors. Figure 4-1
shows a typical installation.

Figure 4.1

AccuTouch touchscreens are available for most monitors. Each monitor may
pose unique installation issues. Although your monitor may not be a standard
touchmonitor product from Elo, we may have had some experience with it.
Contact Elo Technical Support for more information.

This section assumes you have already determined compatibility between the
touchscreen and the monitor. A touchscreen installation kit is available from Elo
(P/N 458095-000), which includes the commonly used materials needed for
installation.

Most monitors require complete disassembly, including removal of the CRT, to
install a touchscreen. Disassembling the monitor can be a dangerous procedure
if done improperly. Before proceeding, review the rest of this chapter. Basic
assembly skills are required. Seek qualified help if you have any doubts about
your ability to complete the installation.

Any damage to the monitor or the touchscreen as a result of improper
installation is the installer’s responsibility.

Without prior approval of the monitor manufacturer, you will probably void the
monitor's warranty by disassembling it. Also, it will be necessary to recertify the
monitor and touchscreen system for regulatory agencies (such as FCC,
UL/CSA, TÜV, CE, etc.) if those certifications were originally present and need
to be maintained for your intended application. (Elo offers touchmonitors with
full agency approvals.)

Handle the touchscreen with care. Avoid excessive handling and stress on the
touchscreen cable.

Bezel Design

The following graphic displays some bezel ideas in order to help you mount the
bezel to the touchscreen.

T esting Components

The display must be in good working order before beginning the installation of
the touchscreen. With a new display, it is suggested that you test the display by
running it overnight. Do not leave a constant image at normal brightness on the
screen during this test, as it may burn an image into the screen.

Familiarize yourself with the operation of the touchscreen and controller before
you proceed with the installation. Use the COMDUMP, BUSSTAT, or
TOUCHES programs as described in Appendix A to test serial and PC-Bus
controllers while the touchscreen components are arranged on the work surface.

Currently, there is no separate diagnostic test for USB controllers.

Installation Steps

The installation process consists of the following steps:

• Disassembling the monitor.

• Attaching the touchscreen to the CRT.

• Installing transient protection.

• Optionally installing an internal serial controller.

• Interfacing the touchscreen or serial data cables to the exterior of the monitor.

• Reassembling the monitor.

• Optionally sealing the monitor.
Specific compatibility may not be confirmed until well into the installation.

Suggested Tools

The following is a list of tools that may be needed to install the touchscreen.
Some of the tools are optional, but will be useful if needed.

• Long (at least 9 inches, 200 mm) flat blade screwdriver with insulated
handle.

• Clip lead or heavy-gauge wire.

• #2 Phillips screwdriver.

• Scissors.

• X-Acto knife (No. 11 blade) or hand milling tool.

• DB9 hole punch.

• Cable ties.

• Household glass cleaner.

• Paper towels.

• Small containers or plastic bags to hold loose parts.

The Elo Touchscreen Installation Kit (P/N 458095-000) is also recommended,
and includes commonly used materials needed for touchscreen installation. This
kit is useful for identifying preferred materials for your own procurement and
may also be cost-effective and convenient when purchased for a limited number
of installations. A copy of the monitor manufacturer’s service manual is also
useful, if available.
