CHAPTER
C HAPTER 1 I NTRODUCTION
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.
Applications for touchscreens include:
• Public Information Systems
• Multimedia
• Retail and Point-of-Sale
• Process Control
• Instrumentation
•Gaming
• Ticket and Lottery
• Simulation and Training
• Education
The AccuTouch®Model:SCN-AT (E274) touchscreen product line is based on
patented resistive technology. The AccuTouch touchscreen has gained a
worldwide reputation for fast, responsive accuracy and reliability. It has an
unmatched combination of performance, size, and environmental adaptability.

1-14 Elo Entuitive Touchmonitor
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.

1-15 Elo Entuitive Touchmonitor
Care and Cleaning
Handle the touchscreen with reasonable care when not integrated into a monitor.
Do not pull or stress the cables.
Clean the touchscreen with Isopropyl 99% and lint free wipes. Always dampen
the wipes and then clean the touchscreen.
For operating and storage specifications, refer to Appendix C.

CHAPTER
C HAPTER 3 T OUCHMONITOR I NSTALLATION
Elo purchases and resells a variety of monitors, called Touchmonitors, both
CRT and LCD, with touchscreens and all related components fully installed. If
you are installing components rather than a touchmonitor, proceed to Chapter 4,
install your touchscreen components, then return to this chapter.
Touchmonitor Benefits
Touchmonitor benefits include:
• Single source for touchscreen and display.
• Professionally engineered touchscreen installation.
• UL,cUL, FCC, TÜV, CE, and other agency approvals.
• Elo warranty.
• Plug-and-play convenience.
Controller boards, cables, and power supplies may also be ordered separately.

3-22 Elo Entuitive Touchmonitor
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 not 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.

Next, refer to the appropriate page to continue your installation:
Touchmonitor with Internal Serial Controller
Contents
This configuration includes a touchmonitor with an internal 2210 serial
controller and a serial cable. Actual configuration may vary due to third-party
integrations.
Installation
The 2210 controller is internal to the monitor and is shipped preconfigured for
use with Elo software.
Complete these steps:
1Plug the DB9 male end of the supplied serial cable into the DB9 female
connector typically labeled "Touch Interface" on the back of the
touchmonitor case.
2Plug the DB9 female end of this cable into the computer's DB9 serial port. If
you have a 25-pin serial port, use a DB9 male to DB25 female adapter.
Proceed to “Where to Go from Here” on page 3-30.

2210MX External Serial Controller
Contents
This configuration includes a 2210 serial controller in a small enclosure with a
keyboard power tap or external power supply and connecting cables.
Installation
Complete these steps:
1Configure the controller
2Connect the touchscreen controller and the supplied cables.
Configure the Controller
The controller is shipped preconfigured for use with Elo software. No changes
are necessary for most users. Specific settings and options available for your
controller are listed in Appendix B.
The 2210MX External Serial Controller is typically shipped configured at 9600
baud. If your software does not support the 2210 directly, you may operate the
2210 in E271-140, E261-280, or E281A-4002 emulation modes. See B for
jumper settings.
Additional technical information about the 2210 controller can be found in the
SmartSet Touchscreen Controller Family Technical Reference Manual,
available at www.elotouch.com/support/dwnldmnls.asp.
Connect the Controller
CAUTION Before using a keyboard power tap, be sure sufficient power is available for the
touchscreen controller or damage may occur to the computer.
Before connecting a keyboard power tap to the controller, be sure that power to
the computer is OFF. Connecting a keyboard power tap to a powered computer
may seriously damage the computer or the controller.
Complete the following steps if you are using a keyboard power tap:
1Two different keyboard power taps are available. Use Elo P/N 980773-000 if
you have a standard keyboard connector and Elo P/N 388923-000 if you have
a PS/2 keyboard connector.
2Unplug the keyboard from the computer.
3Plug the male connector on the Yend of the adapter cable into the keyboard
connector on the back of the computer.
