Power for the LCD backlight is supplied by an inverter circuit, which is
integrated on the LCD controller board in the 12.1” LCD. While the
inverter can be set to various levels of brightness, the 12.1” LCD can
only turn the backlight to maximum brightness or a lower brightness
for dark environments. The inverter generates the high voltage
necessary to start and run a dual CCFL backlight.

Chapter 3: Installation 3-11

Calibrating the Touch Screen

Be sure to observe for the following Touch Screen calibration
guidelines:

• Calibrate the touch screen as part of the installation process.

• Recalibrate the touch screen when the system is installed at its final

location.

• Recalibrate whenever the terminal is moved to a new location.

• Recalibrate the touch screen anytime the system has been

disassembled for servicing.

• The Touch Screen can be calibrated using MicroTouch (Windows)

or Microcal (DOS).

Calibration Using MicroTouch (Windows)

1. From the Windows Start button, select Settings→Control

Panel→MicroTouch Touchscreen.

2. From the MicroTouch Touchscreen Properties screen, select Calibrate

to begin calibration.

3-12 Chapter 3: Installation

3. The following screen is displayed with two targets. Place your

finger on the target that has a finger icon pointing towards it and
hold it until the statement Touch Enable is displayed over the finger
icon.

Note: For best results, press the screen near the circle and then
slide your finger onto the circle without raising your finger from
the screen.

4. Using the same method as above, touch the circle near the upper-

right corner of the screen.

Place your

finger here

Chapter 3: Installation 3-13

5. The MicroTouch Calibration dialog box then appears. Do not touch

the screen until this dialog box is no longer displayed.

6. From the Calibration Complete screen, select Done.

7. Select Close to exit the MicroTouch program.

8. From the Control Panel, select File→Close to exit the Control

Panel.

3-14 Chapter 3: Installation

Calibration Using Microcal (DOS)

The calibration program looks at where your finger is when you lift it
off the screen, not where you touch it. Therefore, calibrate the screen as
follows:

1. Touch the screen near the calibration target.

2. Keep your finger on the screen and slide it to the center of the

target.

3. Hold your finger firmly on the target for two seconds, then lift it off

quickly.

4. Verify that the calibration was set accurately before making a

service call. Perform the calibration again if necessary.

If cursor is not stable, or false touches are suspected, run the Noise
Check Utility from the Microcal program. Choose the recommended
frequency (the one with the lowest noise level). This should also be
done if the Touch Screen is still not calibrated after one attempt to
recalibrate it.

1. Set the video resolution by going to the Tools menu, Video and

selecting 800 x 600 256 colors.

2. Go to the Tools menu, select Noise Check.

3. Follow the instruction prompts. Choose the frequency with the

lowest noise level.

Application software can possibly generate a dialog box from the
Touch Driver, with the message that the touch screen needs to be
recalibrated. If the screen appears to be working normally, then this
message can be ignored. There will be a check box labeled Do not
show this message again. Make sure this box is checked.

Chapter 3: Installation 3-15

Summary

If there is a Touch Screen calibration issue during or after installation,
take the following actions in the order listed:

1. Recalibrate.

2. If recalibration is unsuccessful after two attempts, then run the

Noise check to change the frequency.

3. If you are still unable to calibrate, change the touch screen glass.

4. The final step is to replace the Touch Controller Board. If this

corrects the problem, then the old glass is probably OK to reuse.

3-16 Chapter 3: Installation

Screen Saving Feature

The display has a time-out function that causes the display to go blank
after several minutes of inactivity.

The screen saving feature is controlled by NCR platform software that
comes as part of the standard terminal operating system image. This
functionality is also available by installing the Retail Platform Software
for Windows LPIN (D370-0548).

Touching the touch screen returns the display from screen saver mode.

See Chapter 4, Programming, for information on how to program the G
controller for proper panel OFF/ON sequencing.

Chapter 4: Programming

Device Interfaces

Caution: When performing touch screen calibration on the 5964 LCD
under Windows 95, note that if the terminal is shut down improperly
the calibration may be lost. To avoid this situation, verify the terminal
is properly shut down after calibrating the touch screen. To shut down
correctly, select the Start button in the lower left corner of the screen,
and then select Shutdown. When the terminal is powered up, the
recent settings will be retained.

Note: This procedure is especially important during initial calibration
of the display in order to ensure that at least a base set of reasonable
calibration parameters are preserved in the Windows 95 Registry.

This chapter provides information on the device interfaces.

12.1-Inch DynaKey Video Drivers

When using 12.1 displays the required video drivers depends on which
class-model of the terminal that it is configured with or if the display is
being used with the C&T 69000 LCD SVGA Video Adapter card. The
drivers are available on NCR software CD; NCR 74xx-Base and System
Client 3rd Party Drivers, D370-1111-0100 (previously, G370-0830-0000).
Drivers and installation instructions are available on this software CD
for Win. 3.1, Windows 95, Windows NT 4.0 and Windows 2000.
Drivers are not needed for DOS.

If the display is being used in a Dual Display configuration, refer to the
NCR Retail Customer Information Display User's Guide (BD20-1431-B) for
specific OS, driver, and installation information.

4-2 Chapter 4: Programming

Wedge Controller Interface

Refer to the Wedge Controller 1.0 Implementation Specification
(497-0001747) and the Trigantor Device Specification (006-8601066) for a
complete description of the Wedge Controller (Wedge)

The Wedge consists of a microcontroller (8051) and associated logic
(including the Trigantor ASIC) which supports certain devices that can
be logically connected in series with a standard PC keyboard. It
controls input devices such as the ISO 3-track MSR and keyboard data,
and merges the data from any of them into the data stream of a PC
keyboard. It also controls the operation of the speaker.

Touch Screen Interface

The touch screen interfaces to the terminal via the terminal’s standard
RS232 port. The 5964 LCD uses the Serial/SMT3 controller referenced
in that document.

There is a bar code label (two-dimensional PDF417 symbology)
attached to the tail of the touch sensor that contains the 25 point
linearization parameters associated with that particular touch sensor.
This bar code label is scanned and the resulting data block is
programmed into an on board non-volatile EEPROM on the 5964 LCD
Display Main Board during the manufacturing process. This provides
the touch controller with course calibration data prior to initial system
power-up.

After the course calibration data has been stored, all that is required to
calibrate the sensor when installed on the LCD is to run the two-point
extended calibration routine. The extended calibration routine has the
two touch points moved inward 12.5% from the corners of the display
for easier access.

The MicroTouch firmware defaults to the following communication
parameters:

Chapter 4: Programming 4-3

• 9600 baud

• No parity

• 7 data bits

• 2 stop bits

• Format hex

• Autobaud enabled

For better compatibility with the MicroTouch DOS and Windows
drivers and mouse emulator it is desirable to select the following
communications parameters:

• 9600 baud

• No parity

• 8 data bits

• 1 stop bit

• Autobaud disabled

These parameters are loaded into the on-board EEPROM chip during
manufacture of the board.

The Windows driver expects a 9600N81/tablet configuration. Both the
DOS driver and the mouse emulator expect 9600N81, but can run at
2400 baud. The Autobaud feature permits the touch controller to figure
out what baud rate the system is running by examining a command
from the system. The problem is that the system must send the
command first. If the system sends no command (as happens after a
stand-by), the controller does not know the system's baud rate and
does not send any touch coordinate data. This is seen to the operator
as a dead sensor after coming out of stand-by. Disabling Autobaud
permits the touch controller to recover from a stand-by situation,
because it begins immediately sending points when touched after a
stand-by.

4-4 Chapter 4: Programming

MSR Interface

3-track MSR and JIS 2-track MSR heads are available. The harness
from the MSR head plugs into the main board. All decode circuitry
resides on the main board. The decoder is based on the Trigantor chip
currently used in NCR Retail products. The keyboard should not be
used while a card is being swiped in the MSR.

ISO and JIS card formats are supported in the initial release. All MSR
data is sent to the host via the Wedge Controller.

PS/2 Keyboard Interface

A PS/2-style keyboard connector permits alphanumeric entry and non­touch applications to be used through a standard PC keyboard. You
cannot connect and use a Wedge Keyboard in this port.

Panel OFF/ON Sequence

Before turning the Panel Off, turn off the video using Sequencer
Register 1 bit 5 (SR01[S]) in the same manner as IBM recommends for
the standard VGA. To make Video Off more effective, some additional
delay should be included before Panel Off.

By turning the Video Off via SR01[5], the Sequencer is no longer
refreshing the screen. This gives the Sequencer enough bandwidth to
work with the Panel Off logic to do an orderly shutdown of the video
output.

Chapter 5: Service and Repair

Safety Requirements

Carefully follow these safety requirements before servicing the Touch
Screen.

Warning: The 5964 Touch LCD contains hazardous voltages and
should only serviced by qualified service personnel.

Warning: Before servicing the equipment plug your safety strap
into a proper grounding outlet. Failure to do so could damage the
equipment.

Caution: Before servicing the 5964 Touch LCD, power down the
terminal or PC and disconnect the terminal AC power cord.
Disconnect the cables from the PC or workstation to the Touch Screen.

Caution: To protect the internal circuitry from damage, unplug the
AC power cord and then momentarily press the power switch ON to
drain the power supply capacitance.

Caution: The power supply cord is used as the main disconnect
device. Ensure that the socket outlet is located/installed near the
