1INTRODUCTION

Congratulations on your purchase of an Elo TouchSystems Entuitive touchmonitor. Your
new high-resolution touchmonitor combines the reliable performance of Elo’ s touch
technology with the latest advances in CRT display design. This combination of features
creates a natural flow of information between a user and the touchmonitor.

1. Precautions

Follow all warnings, precautions and maintenance as recommended in this manual to
maximize the life of your unit. See page 4 B for more information on touchmonitor safety.

2. About the Product

Your CRT touchmonitor is a color display with the following features:

• 13.8-inch viewable image 0.28mm dot pitch CDT for 15".

• 15.7-inch viewable image 0.27mm dot pitch CDT for 17".

• 18-inch viewable image 0.25mm dot pitch CDT for 19".

TOUCH TECHNOLOGY

1.Touchscreens: An Overview

Typically, users communicate with computers by using a mouse, a keyboard, or a
combination of the two. Users who are not keyboard-literate or mouse-savvy can become
frustrated with how long human-to-computer interactions take.
Computer literacy is learned. This is complicated by the fact that using a keyboard or a
mouse is neither intuitive nor natural for most people.
Touchscreens cut out the learning curve by eliminating keyboard/mouse intermediaries and
allowing a natural flow of information to develop between a user and a computer.
When a user wants to access information or perform a function on a computer with a
touchscreen installed, a touch quickly and accurately does the job that once required
complicated keyboard interactions or precise mouse movements.
A frustrating experience with a computer during a transaction can create dissatisfaction for
your customer. Touchscreens help eliminate unpleasant transactions by creating a natural
flow of information that enhances your product or service. Touchscreens speed up
user/computer interactions. People get what they want faster and are more satisfied with
the process.

2.iTouch Touchscreens

Elo built on its IntelliTouch surface wave technology to create its iTouch "touch-on-tube"
solution. Elo eliminated the clear glass layer between the viewer and the display. iTouch
touchmonitors have been adopted by some of the largest manufacturers in the world in their
next generation games.
Elo CRT gaming monitors offer consistent features across all sizes:

• Touch directly on tube—no touchscreen overlay and no parallax.

• Preserves 100 percent of CRT brightness, clarity, antireflection and color properties.

• More durable and safer than even bonded touchscreen overlays.

• Same fast, accurate, stable performance as Elo’ s IntelliTouch surface wave
touchscreen overlays.

• "Drift free" and not affected by surrounding metal or poor earths/grounding.

• Dual touches are not averaged, allowing extremely fast two-handed play.

• Z-axis for pressure can add a new dimension to games.

• No need for periodic recalibration.

5.Connect the Power Cable

• Your monitor does not include a power cable. You may either purchase a country
specific power cable from Elo (www.elogaming.com), or construct your own custom
power cable (see page 4 for details). Connect the power cable to the AC connector on
your touchmonitor. To protect your equipment against risk of damage from electrical
surges in the power line, plug the touchmonitor’ s power cord into a switched surge
protector, and then connect the surge protector to a grounded (three-pronged) AC
electrical outlet.

• Your touchmonitor has no power switch. Power on your monitor using the power switch
of the surge protector, and check that the power LED is on. If not, refer to page 32,
Troubleshooting.

• After a brief pause the picture should appear. If necessary, adjust the front panel controls
according to your personal preference (see page 13).

• Insert the Elo TouchTools CD-ROM in your computer’ s CD-ROM drive to install the
appropriate touchscreen driver software. Follow the directions starting on the next page
to install the driver software.

6.Installing the Driver Software

Elo TouchSystems provides driver software that allows your touchmonitor to work

with your computer. Drivers are located on the enclosed CD-ROM for the following
operating systems:

• Windows XP

• Windows 2000

• Windows Me

• Windows 98

• Windows 95

• Windows NT 4.0
Additional drivers and driver information for other operating systems are available on the
Elo TouchSystems web site at www.elogaming.com.
Your Elo touchmonitor is plug-and-play compliant. Information on the video capabilities

of your touchmonitor is sent to your video display adapter when
Windows starts. If Windows detects your touchmonitor, follow the instructions on the
screen to install a generic plug-and-play monitor.
Refer to the appropriate following section for driver installation instructions.

7.Installing the Touch Driver for Windows XP, Windows 20001, Me,
95/98 and NT 4.0

NOTE: For Windows 2000 and NT 4.0 you must have administrator access rights to
install the driver.

1.Insert the Elo CD-ROM in your computer’ s CD-ROM drive.

If the AutoStart feature for your CD-ROM drive is active, the system
automatically detects the CD and starts the setup program.

2.Follow the directions on the screen to complete the driver setup for your version of

Windows.

If the AutoStart feature is not active:

1.Click Start > Run.

2.Click the Browse button to locate the EloCd.exe program on the CD-ROM.

3.Click Open, then OK to run EloCd.exe.

4.Follow the directions on the screen to complete the driver setup for your version of

Windows.

8.Installing the Touch Driver for MS-DOS and Windows 3.1

You must have a DOS mouse driver (MOUSE.COM) installed for your mouse if you
wish to continue using your mouse along with your touchmonitor in DOS.
To install Windows 3.x and MS-DOS from Windows 95/98, follow the directions
below:

1.Insert the Elo CD-ROM in your computer’ s CD-ROM drive.

2.From DOS, type d:\EloDos_W31 to change to the correct directory on the CD-ROM

(your CD-ROM drive may be mapped to a different drive letter).

3.Type install and press Enter to start the installation.

4.Align the touchscreen.

You must have already completed Steps 1 and 2 before proceeding. Refer to page 9 of
the Elo DOS and Windows Driver Guide as necessary for additional installation
information.
To run the INSTALL program:

1.Type INSTALL at the DOS prompt in the directory containing the driver install files.

2.INSTALL asks you to select the software to install. Then choose d:\EloDos_W31

from the displayed list.

3.INSTALL also asks you for the paths to use during installation, or you may use its

defaults. INSTALL creates directories as necessary, and warns you if they exist.
If you are updating your software, you may wish to specify the paths containing the

earlier versions, and overwrite the obsolete files. All executable programs are upward
compatible. For a list of differences from each previous version of the drivers, be

sure to select "Differences from Previous Versions" during the installation process.
INSTALL updates your AUTOEXEC.BAT file with the drivers you select.
INSTALL makes a copy of your original AUTOEXEC.BAT file, called

- 13 -

AUTOEXEC.OLD. If you already have Elo driver commands in your
AUTOEXEC.BAT file, they will be commented out.

When INSTALL is finished, it leaves a file called GO.BAT in the subdirectory you

specified. GO loads the touchscreen driver, runs the calibration program

ELOCALIB, and gives you some final instructions.
If you are using Windows 3.1, you will also calibrate the touchscreen within Windows

3.1 with the Touchscreen Control Panel.

OPERATION

1.About Touchmonitor Adjustments

By design, your Elo Entuitive touchmonitor should not require any adjustments.

The factory settings will give you optimum video results with most standard PC video

display adapters.

However, after connecting your touchmonitor you can further optimize the settings to

meet your requirements by following the directions in this chapter.

All adjustments you make to the controls are automatically memorized, so you do not

need to reset your choices every time you unplug your touchmonitor or power it off

and on. If there is a power failure your touchmonitor settings will not default to the

factory specifications.
IMPORTANT: Do not insert conductive metal objects into the monitor's circuitry. The

monitor uses high voltages and the metal edges can be sharp.
Disassembly or realignment of the monitor circuitry voids the warranty.

2.Touchmonitor Controls

You can adjust the screen display by using the plastic knob labeled OSD located on

the right-hand side of the touch controller bracket.

2.1 Using the On Screen Display (OSD)

2.1.1 Push the OSD knob to access the OSD.

2.1.2 Turn the OSD knob to choose the item you want to adjust. The selected item

is highlighted. See figure 1 for OSD menu options.

2.1.3 Push the OSD knob to adjust the highlighted item.

The display unit automatically saves the new settings in about 45 seconds
after your last adjustments. The menu will automatically disappear or you can
push the OSD knob to make the menu disappear.

7-7 Power Saving Test:

-Off Mode:Open the H-Sync and V-Sync, check if the power is under 5W.

8. CONVERGENCE ADJUSTMENT

The CRT is an ITC assembly, however, here is the explanation for readjustment just in
case.

8-1 Make sure that this adjustment is done later than 30 minutes after power on.

Check general ability coarse adjustment and purity adjustment finished.
8-2 Degauss the magnetism of chassis and CRT with degaussing coil. (CRT board also).
8-3 Apply mixed crosshatch signals of red and blue from the signal generator. Nudge the

deflection yoke to equal its inclination up and down, right and left with a temporary

wedge between CRT and the top of the yoke.
8-4 Match the red and blue images at the center of the screen by rotating the Four-pole

magnet A (See STEP-1 in figure for examples). For this adjustment Four-pole

magnet A should be put together.
8-5 Apply mixed crosshatch signal of red, blue and green from the signal generator.
8-6 Match the red, green and blue images at the center of the screen by rotating the Six-

pole magnet. (See STEP-2 in figure for examples).
8-7 If lines are twisted either left hand or right hand (See the STEP-3 in figure for

examples) perform the following:

a. Use Four-pole magnet B to shift convergence of horizontal lines by 5 to 6 mm at

the center of the screen. (For twisted left hand lines, shift blue line downward and
red line upward. For twisted right hand lines, shift red line downward and blue line
upward. Do not shift convergence of vertical lines.)

b. Then realign convergence with Four-pole magnet A.
8-8 Loosen the deflection yoke fastening screw and gently nudge the yoke up and down

to achieve the best overall convergence on the edges of the screen (See STEP-4 in

figure for examples).
Insert wedge at the top of the deflection yoke so that the convergence will not

deviate due to an unsteady deflection yoke.
8-9 Gently nudge the yoke from side to side to achieve the best overall convergence on

the edges of the screen (See STEP-5 in figure for examples).
Insert wedges at the left side and right side of the deflection yoke so that the

convergence will not deviate due to an unsteady deflection yoke. (Do not apply

silicon adhesive to the wedges to prevent them from slipping out).

- 23 -

8-10 Check that the image is horizontal.

If needed, rotate the deflection yoke.

8-11 Recheck the purity adjustment. If purity was adversely affected repeat the purity

adjustment, then recheck convergence when finished.
8-12 Retighten the deflection yoke fastening screw. Do not overtighten the screw, as this

can damage the CRT.
Tightening torque:20 ±2 kgf.cm
8-13 Align the horizontal line convergence at the center of the screen with the Differential

coil (See STEP-6 in figure for examples).
8-14 Align the horizontal line convergence at the corner and of the screen with the

Differential resistor VR-YV. (See STEP-7 in figure for examples.)

8-15 Align the center vertical line convergence at the corner of the screen with the Vertical

Isotropic Astigmatism resistor VR-YH (See STEP-8 in figure for examples).
8-16 Align the center vertical line convergence at the corner of the screen with the vertical

ISO tropic astigmatism resister VR-YH (See step-9 in figure for examples for 19”

only).
8-17 Recheck convergence at the center of the screen. If needed, realign with the Four-

pole magnet A and the Six-pole magnet.

8-18 Insert wedges as shown is STEP-9 of figure (at the top, bottom, and right side of the

deflection yoke). Secure them with silicon adhesive and polyester tape. Remove any

temporary wedges while keeping convergence aligned.

8-19 If the convergence on the fringe areas in still not acceptable, place one or more

Permalloys around the funnel to achieve the best effect. Then press these Permalloys

onto the funnel. Verify convergence around all edges of the screen. (See STEP-10 in

figure for examples).

NOTE

In the above step, do not place the Permalloys closer than 20 mm from the HV

anode cap. Do not tape them over any paper labels or secure them with silicon

adhesive.

8-20 After completion of adjustment, apply locking paint to the movable portions of the

deflection and convergence yokes to secure them.

8-21 Make adjustment so that the value of white window pattern from the signal generator

is below that under the condition of 100 cd/m2 brightness at the standard condition.
