Chapter 2: Diagnostics

Power-On Self-Test (POST) Errors Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem.

If a system boot is incomplete (for example, the system is turned off while it is going through the POST), then the next time the system is powered on you may get a message stating that the previous boot was incomplete. The BIOS will revert to safe values for the chip set, caches, I/O components, etc. This provides the best possibility of returning to the Setup routine and to normal functioning, but these values do not always produce maximum system performance. To achieve maximum performance after the BIOS has reverted to safe values, re‐enter Setup and select the maximum performance values.

If, for example, the terminal was simply turned off during POST, you can return to the maximum performance values by simply entering Setup and exiting or by rebooting.

11 Cache Memory Bad

Before declaring the motherboard beyond all hope, eliminate the possibility of interference by a malfunctioning add‐in card. Remove all expansion cards except the video adapter. • If the beep codes are generated even when all other expansion cards are absent, the motherboard has a serious problem. Consult your system Support. • If the beep codes are not generated when all other expansion cards are absent, one of the add‐in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens again. This will reveal the malfunctioning add‐in card.

8 Display Memory Error

If the system video adapter is an add‐in card, replace or reseat the video adapter. If the video adapter is an integrated part of the system board, the board may be faulty.

Chapter 3: Troubleshooting

Introduction The following Conditions are discussed in this chapter to help you determine system problems.

• No Display • Unit Will Not Boot/Blue Screen While Booting • Random Blue Screens While Running • Slow Performance While Running • Noise From Unit • LCD Display Distorted or Lines on Screen • Screen Flickering • Hard Disk Drive Not Working/Recognized • Keyboard/Mouse Not Working • Keyboard/Mouse Not Working • MSR Not Working • Cash Drawer Not Working • Ethernet LAN not working • Wireless LAN not working • Integrated Customer Display not working • Powered serial or USB peripherals not working • Motion sensor not working • IRDA not working • Integrated Speakers not working

3-2 Chapter 3: Troubleshooting

Getting Started To Turn Unit On/Off: Use the logic On/Off Switch on the lower right of the system (below the MSR). If this doesn’t work, check the switch on the power supply in the base of the system. This switch needs to be on. When off, this is equivalent to unplugging the system from AC power.

Note: There is a delay of several seconds before information begins to display on screen.

BIOS Setup: To enter Setup, reboot the system and press <DEL> when the screen image first appears.

Hardware Changes: Power the system off and disconnect it from AC prior to opening the unit or making any internal hardware changes as described in this document.

Hot Plugging: The following can be hot‐plugged for diagnostic purposes as described in this document.

• Keyboard • VGA CRT • Standard USB • Cash Drawer • Ethernet However, you must power off before connecting USB and serial devices. Also, power off before connecting any other peripheral not listed above.


Condition: No Display

No Power LED 1. Check that the unit is plugged into AC.

2. Check that the AC line cord and extender cord are securely plugged into the 7402 power supply.

3. Confirm that the customer’s AC breaker or fuse is OK and that there are no other AC quality issues.

4. Check that the Power Supply Rocker Switch is on.

5. Use the On/Off Switch to power on the unit.

Still No Power LED 1. Lift the display and check the Power Switch Harness connections

on both ends (Power Switch Board and Motherboard).

2. Check the two main power supply harnesses connections at both ends (Power Supply and Motherboard/7402 Retail Board).

3. Both the 20 pin and 4 pin power connectors must be plugged into the motherboard.

4. Check that the PCI riser card (if installed) and DIMM memory modules are correctly seated.

5. Check for correct seating, bent pins, or shorting conditions on any connectors.

6. Be sure to unplug the AC or switch off the Power Supply Rocker Switch before changing any connections.


If the above are OK then the Power Supply may be faulty. If exchanging the Power Supply does not correct the problem, or if the Power Supply is confirmed to be OK on another machine, then do the following:

• Check for correct seating or any bent pins on CPU (Note: you must follow the correct procedure to reattach the CPU heat sink after doing this).

• Exchange the Retail Daughter Card. • Exchange the Motherboard.

Power Indicator LED is Illuminated Note: This is different than on the 7454. 7454: Power LED turns on when the CPU begins running code

7402: Power LED turns on as soon as the power supply comes up

Determine whether or not the CPU is still running – Do the following if possible before rebooting:

1. Hot‐plug a keyboard and check if key presses bring the display back. If so it could indicate:

2. Problem with customer’s screen saver or O/S power management settings

3. Problem with NCR Fit Client or equivalent software installation or settings

4. Problem with motion sensor hardware:

– Check connection of LED/motion board harness to retail daughter card

– Check harness from Retail daughter card to motherboard – Connector (corner of motherboard near buzzer)

If there is still no display check to see if the Caps Lock indicator will turn on or off in response to the caps lock key. If so, this could indicate a Backlight Inverter problem.


Caps Lock Light Responsive BIOS settings Problem: The display settings in the BIOS North Bridge menu must be as follows:

LCD (LFP) Type 800 x 600 LVDS

VBIOS (default) if your only display is the integrated

Display Type

LCD LFP+CRT if an external CRT is connected in addition to integrated LCD

Windows Display Driver Settings Problem: • Under Control Panel ‐> Intel Extreme Graphics, confirm that

the LCD display is enabled. • If you are using Extended Desktop to get dual independent

displays, confirm that the display you want to be primary remains the primary.

• If you need to add/remove displays (i.e. CRT) it is recommended that you shut down first. When you power up, ensure the BIOS Display type is correct for LCD only or LCD+CRT (see above).

Backlight Inverter Problem:

Warning: High voltage. Power down unit before proceeding.

• Check the inverter harness to motherboard; confirm that it is fully seated on both ends.

• Check that the inverter module has not come loose from its mounting behind the LCD.

• Check that both backlight cables from the LCD panel are plugged into the inverter module.

• Power up the unit again. If there is still no display then continue with the following steps below.


LCD Problem: • Confirm LVDS adapter board is fully seated (small daughter

card mounted directly on motherboard) • Confirm LVDS LCD cable fully seated into the LVDS adapter

board and into the LCD panel

Display Settings or Driver Problem: If the unit booted successfully into Windows but later is found with no display, the display driver settings may have been changed so that the LCD is not enabled. Try the following:

• Use the On/Off Switch to power the unit off then on again. Let it to boot Windows.

• If the image on the LCD screen disappears while the Windows Splash screen is displayed there may be a driver settings problem. If so, continue with the following steps. – Power off, connect a CRT monitor to the VGA port, and

then power on again and boot Windows.

– Assuming you see the Windows desktop on the CRT, use Control Panel ‐> Intel Extreme Graphics to enable the LCD display.

– If Windows is hanging with no display even on the CRT, this indicates a driver issue and you should power cycle and try booting in Safe Mode (hit F8 when the system starts to boot from the hard disk).

– If Windows boots to the desktop in Safe Mode you should confirm that you are using the NCR‐provided (supported) driver versions for the display and other system devices. Also check for valid versions of any drivers you added for non‐NCR devices.


Caps lock light Not Responsive If the Caps Lock light does not respond on the keyboard this could indicate a hardware problem, preventing boot up. Experienced developers in a lab environment can connect a POST card to the PCI slot, but this requires lifting the retail daughter card and is recommended only for those familiar with the hardware.

POST Code: • See the AMI BIOS8 Beep Code and Checkpoint document for

code descriptions. You may hear a beep code of one long beep followed by several shorter beeps. The number of short beeps indicates the type of problem the BIOS is reporting. If you connected a POST card the numeric error code may point towards one of the problems described below. If not, contact NCR with the details of what you see.

BIOS Flash: • If this happened immediately after a BIOS update was

performed there may have been an error that will require BIOS crisis recovery.

Memory Problem: • Check that the memory DIMM is fully seated in the socket. If

unsure, disconnect AC, remove and reseat the DIMM. • Swap with a DIMM from a known good NCR 7402 system. • Move the DIMM to the other slot. • Ensure you are using only the NCR‐supported DIMMs. For

example, ECC DRAM is not supported.

PCI card problem: • If you have a PCI Riser Card and a PCMCIA/RS‐232 card in

your system, all the PCI connectors must be fully seated.


Retail Daughter Card Problem: • Check Daughter Card power connector (heavy‐gauge wires

from Power Supply) • Check the Daughter Card Wedge Cable and USB/GPIO cables.

CPU/Heatsink Problem: Heatsink Caution: CPU can stick to the heat sink and be damaged when the heat sink is removed from the board. Follow the next steps only if you have experience working with devices on the motherboard.

• Check for CPU overheating and/or not inserted properly. • Check that the CPU fans are running. • Check the CPU temperature under BIOS Setup ‐> Advanced ‐>

Hardware Health screen. Temperatures above 65C at idle indicate possible cooling solution trouble.

• If the fans are OK, make sure the heat sink is not loose. All four screws holding the heat sink to the motherboard should be snug, but not over tightened.

• Check that the CPU is fully seated in the socket. • Ensure that you are using an NCR‐supported CPU. This must

be either a 2GHz Celeron or a 2.4GHz P4, 400MHz Front Side Bus. 533MHz is not supported until a future motherboard release.


Condition: Unit Will Not Boot/Blue Screen While Booting If there is a displayed image but the system hangs before completely loading the operating system, follow the suggestions in this section.

If system hangs before anything is displayed (or you see only a brief display), see the No Display condition.

System Hangs in POST (BIOS)

POST Code or Beep Code There may be a numeric code in the lower right part of the display, or you may hear an audible beep code (one long beep followed by several shorter beeps). See the AMI BIOS8 Beep Code and Checkpoint document for code descriptions.

CMOS Problem • Check that battery is correctly inserted on the motherboard • If prompted to run BIOS setup, do so, and be sure to save changes

when exiting.

Memory Problem Symptoms: BIOS reports an incorrect amount of RAM. System hangs at random points during POST and OS Load.

• Check that the DIMM(s) is fully seated in the socket. If unsure, disconnect the AC, remove and reseat the DIMM(s).

• Swap with a DIMM from a known good NCR 7402 system • Move the DIMM to the other slot. • Ensure you are using only the NCR‐supported DIMM(s). For



Hard Disk Issue • Ensure that the hard drive power and data cables are correctly

seated at both ends. • If the BIOS detects a hard drive type correctly, check for a physical

problem on the drive or problems creating the drive image.

Peripherals • Non‐NCR USB peripherals may have trouble with Legacy USB

support enabled in the BIOS. Go to BIOS Setup ‐> Advanced ‐> USB Configuration to disable it.

• If you are in doubt whether a peripheral is causing a system problem, try disconnecting the peripheral and then power cycling the system.

CPU/Heat Sink Problem Heatsink Caution: CPU can stick to the heat sink and be damaged when the heat sink is removed from the board. Follow the next steps only if you have experience working with devices on the motherboard.




• Check that the CPU is fully seated in the socket. • Ensure that you are using an NCR‐supported CPU. This must be

either a 2GHz Celeron or a 2.4GHz P4, 400MHz Front Side Bus. 533MHz is not supported until a future motherboard release.


System Hangs During OS Load • Confirm that the system is not waiting for a login. • Confirm that the correct display resolution is 800x600 (12‐inch

LCD) so that no information spills off the side of the screen, and that the vertical rate is valid for the VGA CRT (if present). Use Control Panel ‐> Intel Extreme Graphics to check.

• If dual display (i.e. LCD+VGA) is enabled, confirm that the correct display configuration is connected.

Driver Problem If the unit booted successfully into Windows but later is found with no display, the display driver settings may have been changed so that the LCD is not enabled. Try the following:


• If the image on the LCD screen disappears while the Windows Splash screen is displayed there may be a driver settings problem. If so, continue with the following steps. – Power off, connect a CRT monitor to the VGA port, and then

power on again and boot Windows.

– Assuming you see the Windows desktop on the CRT, use Control Panel ‐> Intel Extreme Graphics to enable the LCD.




BIOS Version Use only the BIOS versions approved by NCR. Contact NCR if you are unsure. The BIOS version displays at the top of the first screen when you enter BIOS setup.

Network Problem If you have loaded a networked application, check that the network connection is OK. Verify that the network protocol is OK by running a standard application, such as Internet Explorer, or try to browse files manually on another machine in your network using the same protocols.

Hardware or ROM Problem on LVDS Adapter Board To confirm this, exchange the LVDS adapter board from a functioning system.


Condition: Screen Flickering

Backlight Inverter Problem Warning: High voltage. Power down unit before proceeding.

• Check the inverter harness to motherboard; confirm that it is fully seated on both ends.

• Check that the inverter module has not come loose from its mounting behind the LCD.

• Check that both backlight cables from the LCD panel are plugged into the inverter module.

• Power up the unit again. If there is still no display then continue with the following steps below.

LCD Problem • Confirm LVDS adapter board is fully seated (small daughter card

mounted directly on motherboard) • Confirm LVDS LCD cable fully seated into the LVDS adapter board

and into the LCD panel • Check for shipping/handling damage to system that may have

damaged the LCD screen or the backlight tubes inside the LCD


Condition: Hard Disk Drive Not Working/Recognized • Use BIOS setup to determine whether BIOS recognizes the hard

drive. If not, ensure that the hard drive power and data cables are correctly seated at both ends.

• Ensure that you use the NCR‐provided hard drive cable. Other cables may not support the ATA‐100 drive interface.

• If the BIOS detects the hard drive type correctly, check for physical problems on the drive or problems in creating the drive image.

Condition: Keyboard/Mouse Not Working • Check that the PS/2 keyboard is plugged into the lower (purple)

connector. A PS/2 mouse connects to the upper (green) connector. • Windows 2000 and XP may not recognize the PS/2 keyboard or

mouse if you attach them after the system has booted. • Check the Retail Daughter card power connector (heavy‐gauge

wires from power supply). • Check the Retail Daughter card wedge cable (from the

motherboard, near the PS/2 connector). • USB Keyboard & Mouse: If you have a non USB‐aware OS (DOS,

Win NT), be sure Legacy USB support is enabled in the BIOS.


Condition: Touch Not Working or Not Calibrated If there is no touch response at all, or the cursor bounces around when the screen is touched, check the following:

Use the TouchWare Diagnostics Select Start Programs TouchWare TouchWare.

Go to the Hardware tab. Select Find Touchscreen (using the keyboard commands or a PS/2 mouse). The touch screen should be on COM3.

Touch Not Detected 1. Check that the serial cable from the Retail daughter card to the

motherboard is fully seated on both ends. Note that on the motherboard it plugs into 2 connectors.

2. Confirm that all harnesses on the Retail Daughter Card are connected to the correct Motherboard connectors and firmly seated. Check the labels on the harnesses against the Motherboard connector label (pasted on the terminal).

3. Uninstall the Touch Driver; reinstall. Be sure to select 2‐point if prompted for calibration method.

4. Touch uses serial port COM3. Be sure this serial port is configured correctly in your operating system (and not disabled in BIOS Setup).

COM3 Settings: 9600, 8, N, 1, No flow control. Usually the OS default settings are OK.


5. Replace the Retail Daughter Card. When you replace the Retail Daughter Card or re‐image the Hard Drive, Windows may display a dialog box indicating that the Hardware Calibration Data does not match the Windows Registry settings. Answering either OK or Cancel is not important, provided you perform the 25‐Point Linearization before placing the terminal back into service. Caution: Applying OS service packs or fixes could overwrite the touch drivers. Try reinstalling the driver from the Install directory provided on the NCR hard disk load. Do not install any other driver versions.

Touch Is Detected If TouchWare diagnostics finds the touch screen and/or the above items to appear to be OK then check the following:

1. Check that the flat cable coming from the display module is connected to the cable from the Retail Daughter card and that it is not cut or damaged.

2. Confirm that the cables are connected to the correct Motherboard connectors. Check the labels on the harnesses against the Motherboard connector label (pasted on the terminal).

3. The jumper block on the Retail daughter card has settings for resistive and capacitive touch screen. It must match your touch screen type.

4. Check that the touch screen is not cracked or damaged. 5. Check to see if the Capacitive Screen or Bracket is touching the

LCD Panel or the LCD Bracket. (There must be no direct contact.) 6. Check for excessive dirt or debris against the gaskets, especially

along the bottom edge of the screen. 7. Replace the Touch Screen glass. 8. Replace the Daughter Card. If this corrects the problem, then the

old glass is probably OK to reuse.


False Touches Capacitive 1. Check to see if the Capacitive Screen or Bracket is touching the

LCD Panel or the LCD Bracket. (There must be no direct contact.)

2. Confirm that your system is plugged into a properly grounded AC outlet. AC problems can cause unusual behavior of capacitive touch screens.

3. Replace the Touch Screen glass.

4. Replace the Daughter Card. If this corrects the problem, then the old glass is probably OK to reuse.

Resistive 1. Check that the gaskets are present and not damaged.

2. Check for excessive dirt or debris against the gaskets, especially along the bottom edge of the screen.

3. Replace the Touch Screen glass.

4. Replace the Daughter Card. If this corrects the problem, then the old glass is probably OK to reuse.

Calibration 1. If the cursor is consistently away from the touch point, follow the

procedures described in the Windows or DOS calibration flowcharts in the Touch Screen Calibration chapter.

2. If you are still unable to calibrate then change the touch screen glass. (First, check the cable connections on the Touch Screen glass.)

3. The final step is to replace the Retail Daughter Card. If this corrects the problem, then the old glass is probably OK to reuse.


Condition: MSR Not Working • Ensure that your PS/2 keyboard works correctly (if not, See

Keyboard/Mouse Not Working condition) • Ensure that you are using the correct NCR Wedge MSR driver and

have your FitClient MSR profile set up correctly if using FitClient. • Confirm that the cable from the MSR to the Retail Daughter Card is

connected and is fully seated. Check for any loose wires in the connector.

• Ensure that you have the correct reader type for your cards (JIS vs ISO)

Condition: Cash Drawer Not Working • Ensure that the cable for the USB and Daughter Card support is

connected properly on both the Motherboard and Daughter Card ends. On the motherboard it plugs into two connectors.

• Check the Retail Daughter Card power connector (heavy‐gauge wires from power supply).

• Check that you have the correct drivers for the cash drawer installed.

• Confirm that the Cash Drawer itself is OK. If possible, connect it to another system to test.


Condition: Ethernet LAN Not Working • Check the LED indicators on the LAN connector: Link (green) and

Speed (yellow indicates 100Mb/s). • Check for Link LED on the upstream hub or switch.

– Check cable if the Link LED is not present on both ends.

– Try another system on the same cable connection if you are not sure if the problem is the wiring/hub or the system.

• Ensure the LAN driver is loaded. Use the drivers provided by NCR.

• Use the Windows Device Manager to view the properties for the network adapter. This device is working properly should be displayed. – If there are resource conflicts reported, check the source of the

conflict.

– If this still doesn’t work, use the Device Manager to remove/uninstall the device and then reboot to cause a reinstall of the driver (under Win NT the driver must be reinstalled manually).

• Ensure the Ethernet switches, IP routers, and server systems are configured to accept traffic from your NCR system. Confirm your DHCP server is granting a valid IP address, or if you are using a static IP, that the routers pass your IP traffic. Go to a Command prompt and run IPCONFIG to check your IP address.


Condition: Ethernet LAN Not Working • Identify whether your communication path is through a dedicated

wireless access point device, or through another computer system on your premises. Access Point in the discussion below refers to either the dedicated access point or the computer system.

• Eliminate the distance or interference as the possible cause by bringing your NCR system as close to the access point as possible.

• Isolate the problem to the access point, checking whether any wireless devices can communicate through the access point. – Ensure that your NCR system and the access point/wireless

network have the same ESS ID. To check the ESS of a dedicated access point you have to go through a wired Ethernet connection (you must know the IP address) or there may be a serial port for a terminal connection.

– Ensure your access point is set up to accept traffic from your wireless clients, and that the clients are properly logged in (if a login is necessary).

– Check your access point settings for encryption and enable encryption in the wireless clients (if required).

– Run the diagnostics provided by the wireless LAN HW vendor.

• Confirm your IP traffic from the wireless network is passing through the Ethernet backbone and routers correctly. See Ethernet LAN Not Working section above.


Condition: Integrated Customer Display Not Working • The integrated customer display has data and power connectors on

its cable. Check that the connectors have not come loose and are plugged into the proper mating connectors on the system. – Data connector plugs into one of the two serial port headers on the motherboard. Normally this is the one farthest from the CPU. In most configurations this corresponds to Serial Port COM4. Be sure to insert it completely onto the motherboard connector.

– Power connector is small – only two wires. It plugs into one of the two small power connectors on the Retail Daughter Card. You can use either of these power connectors.

• There is also a connector which plugs into the Customer Display module. This is a latching connector and unlikely to become disconnected. If other measures fail to make anything display then you may want to check this connection.

• Check serial port settings – Customer display module optimum port settings are 9600, N, 8,

1, hardware flow control.

– Confirm that the COM4 port is enabled in the operating system, and that the OS reports no resource conflicts.

– Confirm your application software is configured for COM4.

– The serial port IRQ and Address settings can be changed in the BIOS, but normally should be left at their default values. Be sure you haven’t changed these settings to inappropriate values.

– Be sure your application software sends data to the customer display module in the appropriate format and character set.


Condition: Powered Serial/USB Peripherals Not Working • All USB ports on the system provide 5V power up to 500mA, per

the USB specification. • The powered USB ports are referred to as USB+Power. • Your NCR system has two 12V powered USB ports, which are blue

in color. There is also one 24V port. These are intended for NCR‐approved peripherals. – If peripheral device does not power up, the re‐settable fuse on

the motherboard may have tripped. Power the system off and on again to clear this condition.

– If there is still no power to the peripheral, check for problems with the cable or the peripheral itself.

• Connect USB+Power cables only when the system power is off. • You may plug a standard USB cable into the standard USB portion

of any powered USB connector. • NCR may provide a cable for a peripheral device to draw the

power from the powered portion of the USB+Power connector, even though the peripheral does not USB for the data connection. Only NCR‐approved peripherals and cables should be used in this manner.


Condition: Motion Sensor Not Working • The motion sensor may lose sensitivity, or become too sensitive

(false activations), if bright light is shining on it. Sensitivity is less in environments with low ambient light levels.

• If you are not getting the performance you want from the motion sensor due to the light level in your environment, you can consider using mouse/keyboard activity to wake the system from the standby state. Wakeup on touch screen activity may also be supported in your configuration.

• The IRDA/motion sensor cable plugs into a gray header on the Retail Daughter Card. Check that the cable is fully inserted. If the green power indicator LED is not working this probably indicates a problem with the cable connection.


Condition: IRDA Not Working • IRDA (Infrared Data Association) allows wireless communications

to portable devices held within 2‐3 feet of the IRDA transceiver lens on the front of the 7402.

• High ambient light levels or direct sunlight on either the NCR system or the portable device may reduce sensitivity and cause loss of communications. Move the portable device closer to the 7402, or adjust the ambient light level reaching the front of the NCR system.

• IRDA is an adaptation of standard serial ports, and uses the COM2 serial port resources. The COM2 connector is not operable when IRDA is in use.

• Ensure the OS has configured the COM2 port for IRDA. In Windows you can see this by using the Device Manager.

• BIOS – The setting for IRDA on COM2 must be enabled in BIOS setup. There is an option for IRDA, SIR, or ASK‐IR communication format. This should be set to IRDA for most applications.

• Check that the devices you are trying to communicate with are compatible with your protocols and data formats that your IRDA‐enabled application uses.

• The IRDA/motion sensor cable plugs into a gray header on the Retail Daughter Card. Check that the cable is fully inserted. If the green power indicator LED is not working this probably indicates a problem with the cable connection.


Condition: Integrated Speakers Not Working • Ensure that the OS audio driver is loaded and that the audio output

has not been muted or turned too low in volume. In Windows use the Volume Control function in control panel to check this.

• If the sound level from the speakers is not adequate for your environment, or you want high‐fidelity audio, you can plug external speakers or amplifier equipment into the Speaker out port on the motherboard. Note: The integrated speakers are silenced when you connect a cable to the external speaker port.

– The maximum audio output possible on the 7402 is 3 watts per channel into 4 ohms.

• If you are using headphones be sure to set the volume to an appropriate level. Full output level for the speakers will generally be too high for headphones.

• To use the system is to be used in a consumer application where control of sound level is critical, NCR’s customers have been successful either limiting the sound level in software or using an audio attenuator on the headphone cable.

6 9 The Motherboard includes four external RS‐232 ports with the following characteristics:

• Standard 9 pin D‐shell • Ports have a shunt to select between +12 V and normal RI

functionality. The default is +12 V. These ports are marked on the terminal’s back panel with the lightning bolt symbol to signify its powered capability.

• Maximum power capability is 1.5 A from any one port with a maximum combined capability of 3.0 A for all ports. Total +12 V power peripheral current (RS‐232 and USB) must NOT exceed 3.0 A.

• The +12 V outputs from the powered ports are protected by a self‐healing fuse.

• If a port does not have +12 V connected to pin 9, that port can be used to wake up the terminal from Standby via activity on the RI pin.

• The ports are provided in a DB9 dual stack configuration. RS232/A is closest to the board. RS232/B is the upper port.

• Color: Teal or Turquoise

Chapter 6: Power Supply

The power supply provides power to the 7402 Terminal, as well as various retail peripherals through the powered connectors. The power supply is controlled by a logical on/off switch, which permits it to be disabled through software. Other features include: • Auto sensing for 115 VAC/230 VAC operation • Cooling fan Functionally, the terminal’s ON/OFF switch controls the power supply control logic (~REM_EN) to activate the power supply. This switch does not control actual AC mains voltage applied to the power supply.

AC Input The power supply operates with the following voltage ranges.

Range Nominal Vrms

Minimum Vrms

Maximum Vrms

Input Current Max. Arms

Chapter 9: Touch Screen Calibration

General Guidelines Observe the following Touch Screen calibration guidelines:

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

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

• Recalibrate after replacing any component in the terminal.

• Recalibrate whenever a customer reports a touch screen problem.

• Recalibrate if you switch to a new screen resolution

• If the Touch Screen or the Retail Daughter Card is replaced, the 25‐Point Linearization procedure must be performed (Windows only).

• If the calibration is off then follow the Calibration flow chart for corrective action for each operating system.

Considerations When Replacing or Re-Imaging the Hard Drive When you re‐image the hard drive, you may get the following error message: Controller's internal linearity data differs from its last saved linearity data. Do you want to use the internal linearity data?

You should ALWAYS answer this question with Yes and then perform the 2‐Point Calibration procedure. If you still have a calibration problem, see the Windows or DOS Calibration Flowchart to resolve it.

9-2 Chapter 9: Touch Screen Calibration

Touch Calibration Procedures for Windows Use the TouchWare utilities to perform the following procedures:

• 2‐Point Calibration • Cursor Stabilization • 25‐Point Linearization • Restore Defaults Procedure

The TouchWare utilities are available on the NCR Gold Drives for WinNT, Win2K, WinXP Pro and WinXPe.

Note: Customers who are running a Windows application should always use TouchWare to calibrate. Do not boot into DOS and run Microcal.

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 9: Touch Screen Calibration 9-3

Calibration Flow Chart (Windows) The following flow chart shows the proper sequence to perform the various Windows calibration procedures.

Is Calibration Correct?(Test by touching all 4 corners and the edges of the screen.)




2-Point Calibration Procedure 1. From the Windows Start button, select Settings → Control

Panel → TouchWare.

2. From the MicroTouch Touchscreen Properties screen, select Calibrate to begin calibration.


3. Place your finger on the target that has a finger icon pointing towards it and hold it until Touch Enable is displayed beside the finger icon.

Note: There are 2‐Point or 4‐Point Calibration methods available. ALWAYS use the 2‐Point method. If you inadvertently run the 4‐Point method then you must run the 25‐Point Linearization (follow the flow chart beginning at 25‐Point Linearization).

For best results, press the target as accurately as possible. Hold your finger in place until notified by the target and then lift your finger off the target.

4. Repeat this procedure for the other target.


5. A Warning dialog box is displayed while the data is saved. Do not touch the screen until this dialog box is no longer displayed.

6. Test the calibration by moving your finger around on the screen and verifying that the cursor follows your finger. It is also suggested that you Touch all 4 Corners and verify that the cursor moves deeply into the corners.

7. Select Done.

8. If you are satisfied with the calibration results you can select Close to exit the TouchWare program.

If the system is still out of calibration after performing the 2‐Point Calibration then perform the Cursor Stabilization procedure (follow the flow chart beginning at Cursor Stabilization).


Cursor Stabilization Procedure This procedure adjusts the touch screen frequency so the cursor is steady when you touch the screen.

1. In TouchWare, go to the Cursor tab and Select the Stabilize Cursor button.


2. Select Yes to continue.

3. Do not touch the screen during the test.


4. Select the recommended frequency and then select Apply.

5. Test the cursor stability by touching the screen in several places.

Move your finger around the screen. The cursor should hold steady and the cursor movement should be smooth. If you still see erratic or jittery cursor movement then choose the next best frequency and select Apply again. When you are satisfied with stabilization select OK.

6. Perform the 2‐Point Calibration procedure.

If you are still having calibration problems then perform the 25‐Point Linearization procedure (follow the flow chart beginning at 25‐Point Linearization).


25-Point Linearization Procedure The 25‐Point Linearization procedure should be performed if:

• The Touch Screen is replaced • Retail Daughter Card is replaced • Persistent calibration issues not resolved by the 2‐point Calibration

or Cursor Stabilization procedures. 1. In TouchWare, go to the Tools tab and Select the Linearize button.

Perform the 25‐Point Linearization and 16‐Point Accuracy Test. If the Linearize button is grayed out (not accessible) you have to enable the feature.

Enabling the Linearization Function a. Select the Options button


b. Select the Advanced button.

c. In the list of Advanced Features. Check the box for Enable

Linearization. None of the other items should be checked.

d. Select the Close Close to return to the Tools tab. You can

now select the Linearize button.


2. Perform the 25‐Point Linearization. Use the same method for touching the targets as you used in the 2‐Point Calibration procedure.

3. After touching all 25 points select the Continue button to perform the 16‐Point Accuracy Test or select Done to save the Linearization Data. If neither is selected the program will time out and the Original Linearization Data will be restored.


16-Point Accuracy Test 4. Perform the 16‐Point Accuracy Test. Touch each of the targets to

check the accuracy of the calibration.

As each target is touched the vertical/horizontal Error Range is displayed. The acceptable margin of error is less than 1.5%.


If the calibration is still unsatisfactory, or the error range >1.5%, then perform the Restore Defaults procedure (follow the flow chart beginning at Restore Defaults).


Restore Defaults Procedure This procedure returns the touch firmware to the factory default values and is performed to correct severe touch calibration problems.

Note: A keyboard is required for this procedure.

1. In TouchWare, go to the Tools tab and Select the Terminal button.


2. At the Terminal screen press the CONTROL and A keys at the same time [CTRL‐A]. A smiley face is displayed.

3. Enter RD (in CAPS) and then press the [Enter] key. A smiley face

followed by a zero [0] is displayed indicating successful restore.

4. Enter [Alt X] to exit the program.

5. Restart the system.

6. Perform the Cursor Stabilization procedure (follow the flow chart beginning at Cursor Stabilization)

The Microcal utility is used to calibrate the touch screen in the DOS environment. Use this utility to perform the following procedures:

• 2‐Point Calibration • Noise Check • Reset Function


The Microcal 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. Connect a keyboard to the terminal.

2. Start the Microcal Utility.

The DOS command is: Microcal.exe /c3 /ill

Note: This is assuming that the serial port setting has not been changed from COM3.

2-Point Calibration 3. Select the Tools menu (Alt T).

4. Highlight Calibrate 2 point and press Enter.

5. Enter Yes to continue.

6. Touch the screen near the calibration target.

7. Keep your finger on the screen and slide it to the center of the target. Hold your finger firmly on the target for two seconds, then lift it off.

8. Test the calibration by moving your finger around on the screen and verifying that the cursor follows your finger. It is also suggested that you Touch all 4 Corners and verify that the cursor moves deeply into the corners.

9. Verify that the calibration was set accurately before making a service call. Perform the calibration again if necessary.


Noise Check If the cursor is not stable, or false touches are suspected, run the Noise Check 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. From the Tools menu, select 800 x 600 256 colors (for a 12” display) or 1024x768 (for a 15” display).

2. From the Tools menu, select Noise Check.

3. Enter Yes to continue. Do not touch the screen during the test. Press the space bar to start the test.

4. Follow the instruction prompts. Choose the frequency with the lowest noise level.


Note: If you experience erratic behavior with the Microcal Utility, then perform a Reset function from the Tools menu.

Appendix C: Heat Sink Installation

This chapter shows the proper method for applying thermal compound on the CPU and Heat Sink. When replacing the Heat Sink or CPU the proper reapplication of thermal grease must be maintained to ensure proper thermal performance.

Important Precautions: Follow the instructions at the bottom of this page to remove the thermal grease from yourself, your CPU, and other hardware.

Caution: Thermal compounds are sometimes engineered for high electrical conductivity. During application keep the compound away from electrical traces, pins, and leads. Some compounds are slightly capacitive and could cause problems if permitted to bridge two close‐proximity electrical paths.

Caution: Never turn on a computer without a heat sink properly mounted on the CPU and with a thermal interface material between the CPU core and the heat sink. The CPU can be permanently damaged in less than 10 seconds without proper cooling.

Application Instructions: 1. Keep the compound away from the processor, memory, and

motherboard traces and pins. There is a possibility that dust or metal particles and/or shavings carried by the airflow inside the computer case could contaminate the compound and increase its electrical conductivity.

3-2 Appendix C: Heat Sink Installation

2. ONLY the thermal compound should be between the processor and the heat sink. Remove any thermal pads or other interface material from the heat sink before applying the thermal compound. Thermal pads can be scraped off with a plastic tool that will not scratch the bottom. The remnants can then be removed using a Xylene based cleaner, (Goof Off and some carburetor cleaners) acetone, mineral spirits, or high‐purity isopropyl alcohol.

Never use any oil or petroleum based cleaners (WD‐40, citrus based cleaners and many automotive degreasers) on the base of a heat sink. The oil, which is engineered to not evaporate, fills in the microscopic valleys in the metal and significantly reduces the effectiveness of any subsequently applied thermal compound.

3. Clean the mating surfaces completely with a low residual solvent (High‐purity isopropyl alcohol or acetone) and a LINT FREE cloth. If thermal compound was previously applied to the heat sink, the mounting surface should be thoroughly scrubbed and cleaned with a Xylene based cleaner, (Goof Off and some carburetor cleaners) acetone, mineral spirits, or 99% pure isopropyl alcohol. It is important to keep the surfaces free of foreign materials and NOT to touch the surfaces (a hair, piece of lint, and even dead skin cells can significantly affect the thermal interfaces performance). In addition, oils from your fingers can adversely affect the performance by preventing the micronized silver fill from directly contacting the metal surface.

Appendix C: Heat Sink Installation 3-3

4. Tint the bottom of the heat sink in the area where the CPU core contacts it. DO NOT use your bare finger to apply or smooth the compound. Put a finger into a plastic bag and thoroughly rub the compound into the base of the heat sink using both clockwise and counter‐clockwise circular motion. This ensures optimum filling of the microscopic valleys in the metal.

5. Apply the thermal compound to the top of the processor.

6. Use a razor blade or the clean edge of a credit card to evenly spread the compound. You may use whatever tool you choose as long as it is CLEAN and permits you to control the application area and thickness. The layer of compound should be 0.003ʺ to 0.005 thick (Equal to the thickness of about 1 sheet of standard weight paper).

21091

7. RE‐CHECK to make sure no foreign contaminants are present on either the bottom of the heat sink or the top of the CPU. Mount the heat sink on the CPU in the proper orientation per the heat sinkʹs instructions. Assemble the heat sink to the motherboard sled by tightening the four captive screws.

8. PRESS the two surfaces together. Minimize any twisting or lateral sliding, which can cause small voids (air gaps). ANY air gaps will significantly increase thermal resistance in an otherwise GOOD interface. Additionally, sliding the surfaces together can cause one surface to scratch/gouge the other possibly opening up a larger inter‐surface gap which increases thermal resistance.


9. Secure the Heat Sink screws. For optimal results tighten the screws in a sequence. Start one screw until it just engages, then start the opposite corner (diagonal). Continue until all four corners are engaged. Proceed to tighten all screws in a cross‐pattern by tightening one screw a few turns and then move to the next. Repeat until all shoulder screws are mated to the motherboard as shown.

Removing Thermal Compound Thermal compound can easily be removed from hardware using the proper cleaners and tools. For general clean‐up, a cloth or paper towel will work well. Intricate cleaning can be accomplished with Q‐tip swabs. An old toothbrush can often get the compound out of crevices that other tools cannot reach.

CPU Core Use high‐purity isopropyl alcohol or acetone and a bit of careful rubbing. (If you use acetone, do a final cleaning with isopropyl alcohol.)

Caution: Do not use nail polish remover as it contains fragrance oils and other contaminants.

Heat sink Use Xylene based products (Goof Off, some carburetor cleaners and many brake cleaners.) or mineral spirits. High‐purity isopropyl alcohol or acetone is ok as well.

Note: Once you have applied thermal compound it is impossible to remove all of the compound from the microscopic valleys in the heat sink using standard cleaning chemicals and paper or fabric towels. Any subsequent thermal material is applied over the remnants of the original material.


CPU Ceramic

Use any of the following cleaners:

• Any dish detergent (Dawn, Lux, Palmolive, Etc.) • Do not use soap for an automatic dishwasher. • WD‐40, citrus based grease removers (Goo‐Gone, Etc.) • Xylene based products (Goof Off, some carburetor cleaners and

many brake cleaners) • Mineral spirits. (Be careful to keep the mineral spirits away from

the core.) Once the majority of the compound has been removed from the ceramic, small patches remaining on the ceramic can be erased using a soft eraser.

If you use any of the suggested products to remove the thermal compound from the CPU or Heat Sink, always do a final cleaning with isopropyl alcohol to remove any residue from the cleaner.

Your Hands Wash your hands with any dish washing detergent (Dawn, Lux, Palmolive, Etc.) rather than hand soap.
