Introduction From Point-of-Sale to Point-of-Service “The customer is king”, a motto that seems so simple and yet it demands a permanently increasing supply of goods and services, both quantitatively and qualitatively. More customer service and more customer information have transformed the point-of-sale to a point-of-service, as business transactions are becoming more complex and there are growing demands on shop assistants and personnel working on the cash till.
Advantages The low-energy, flickerfree and radiation-free colour monitor of the BA73A is an Active-Matrix-Display in TFT-technology (Thin Film Transistor). Therefore, it is well suited for multimedia applications as it offers brilliant colour representation, an excellent contrast ratio and a high display speed. The screen can be installed directly on the cashier’s desk. Furthermore, it can also be set up on the central unit of a modular BEETLE system.
Delivery Unit Unpacking and checking the Delivery Unit Unpack the parts and check to see whether the delivery matches the information on the delivery note. The delivery comprises of the respective screen module. Controllers and data cables, necessary for operation, can be ordered separately. If damage has occurred during shipping or if the package contents do not match the delivery note, immediately inform your Wincor Nixdorf sales outlet.
BA73A Components Screen Module The screen module represents the main unit of the BA73A. It comprises of a TFT-LCD colour screen, the TFT-interface and an inverter that generates the voltage for backlighting the screen. As an option the screens are available with Touch Screen including a loudspeaker. Behind the cover on the back of the BA73A you connect the cable. Remove the cable cover by pushing it in the direction of arrow (see picture) and then taking it off upwards.
LCD-Controller-A/BA73A “Stretching” is only possible when a separate LCD controller or an adapter (“PanelLink-Bridge”) is used (“D1" Central Processing Unit with Celeron or Pentium III Processor). There is no ”stretching" with the “D2" CPU. If the display element is damaged and the liquid crystal solution leaks out onto your hands or clothing, please wash your hands or clothing immediately under running water for at least 15 minutes, using soap or alcohol.
LCD-Controller-A/BA73A The LCD-Controller-A/BA73A is a plug-in-controller with a PCI-interface. There are two connections for r r a 40-pin MDR connector with integrated COM5 output a 9-pin DSUB female (for COM6) COM5 and COM6 are only ready for operation when the optional COM board is used. The control data and data lines for the TFT LCD display are transmitted to the 50-pin MDR connector via hardware drivers and filters.

Capacative Touch Screen (Option) General The TFT Touch Screen works according to the principle of a change in analog capacitance. It has a glass screen with a transparent, thin-film overlay on the surface. This is fully sealed and protected by a further layer of clear glass. Electrodes on the edges of the screen provide a uniform low-voltage field. As soon as you touch the screen with your finger the contact point is “recognized” by the change in capacitance.
Touch Screen Anti Reflective Etched Surface and protection ClearTek Glass Overcoat Conductive Coating Protective Noise Shield The programming interface of the screen is identical to the mouse interface. Touch Screen Touch Screen and Sleep Mode Using the Touch Screen with a BEETLE System, an entry via touch during sleep mode may lead to a faulty input. During sleep mode nothing can be read from the LCD flat screen.
Touch Screen How to Operate The Touch Screen responds to the slightest contact, therefore you do not have to apply much pressure when working with the screen. This does not only safe time, but is also kind to your joints! Touching the touch glass has the same effect as clicking the left mouse button. You only need to apply a little pressure with the fingertip. In this capacitive process only fingertip contact is recognized.
COM Board I/O-Addresses of COM Interfaces COM Board The four COM interfaces of the COM board have the following I/O-addresses. Please refer to the table for the jumper settings.
COM Board The interrupts IRQ9 and IRQ10 are added for PC application only. For a correct reproduction of the interrupt signals it is necessary that the jumper IR9 to IR15 are not activated. To activate the interrupt request signal the corresponding jumper must be closed. To avoid possible conflicts with already existing plug-in-boards in your system, deactivate those jumpers on the COM board, that are no longer needed (opening the jumpers).
COM Board Assignment of COM port addresses and interrupts (installation details) Ensure that there is no conflict of hardware port addresses or interrupt requests (IRQs) used by your system and the COM Board! Essentially the AT COM Board has been designed to be configurable for a non-shared IRQ9, IRQ10, IRQ11, IRQ12, or IRQ15 for COM5 and a shared IRQ9, IRQ10, IRQ11, IRQ12, or IRQ15 for COM6,7,8 and even COM5. The interrupt requests have to be enabled explicitly by jumpers on the controller.
COM Board IRQ12, most likely conflict Mouse Port or PS/2 Mouse These types of mice are supported by Windows NT through the I8042PRT.SYS driver. The mouse usually has a (small) cylindric 6 pin connector. It seems that these types of mice mostly will use IRQ12. Some systems, however, allow to disable the mouse port in the BIOS Setup.
COM Board The AT COM Board manual numbers the COM ports from 5 to 8. The origin of this numbering is from the BEETLE, which has COM1 to COM4 on the motherboard. It is recommended for consistency, that you use this numbering also, regardless whether you have e.g. a BEETLE (with COM ports 1,...,4) or a PC (with e.g. only COM1 and 2). To provide for a numbering according to that, the following procedure is recommendable: 1.
COM Board This will be impossible for hardware reasons! The problem is, that in such a case on the AT bus two different hardware instances would be fighting for the same IRQ! Refer to the technical information about your system for the details you need! If you configured COM ports to share a common interrupt and ‘Permit Share’ is not set to 1, you could use all COM ports but only one at a time.
COM Board Using shared interrupts for COM ports under Windows 95 Under Windows 95, sharing COM ports doesn’t require special provisions other than correctly specifying the resources used in the Device Manager. However, in addition to avoid port address conflicts, you must ensure that no two different pieces of hardware on the AT bus are fighting for the same IRQ! Using COM ports under Windows 3.x Windows 3.x does not allow interrupt sharing! Windows 3.

LCD-TFT Adapter A-Celeron LCD-TFT Adapter A-Celeron/Pentium III LCD-TFT Adapter A-Celeron If your BEETLE is equipped with a “D1" or ”D2" CPU the TFT adapter can be connected with the CPU without LCD-Controller-A and without COM board. The LCD TFT adapter-A is a submodule of the CPU which is necessary for the connecting process. The optional touch function is to be realized internally via the COM2 interface.
Resistive Touch Screen (Option) General The resistive TFT Touch Screen is constructed of a hard-coated polyester topsheet that is overlaid on a conductively-coated glass layer. Voltage is applied to the topsheet. As the user touches the screen, the topsheet compresses into contact with the glass layer, and current flows to the four corners in proportion to the distance from the edge. The controller then calculates the position of the finger or stylus, based on the current flow.
Construction of the resistive Touch Screen: Hard-coated polyester topsheet Adhesive Glass substrate with spacer dots How to Operate Touching the touch screen has the same effect as clicking the left mouse button. You only need to apply a little pressure with the fingertip. In this resistive process not only fingertip contact is recognized. The screen does react in any way if touched, for example, with a stylus. The recommended material for a stylus is polyacetal.
Cleaning Instructions Always turn off the system before cleaning. The surface of your Touch Screen should be cleaned with a water-based solvent or a non-abrasive cleaner.Do not use solvents containing acetic acid or methylene chloride. Use a soft, fine-meshed cloth to clean the surface. Dampen the cloth slightly and then clean the screen.
Installing and Securing the Screen into Place The screen can be easily installed as a table top terminal. Securing into Place Remove the footed stand and screen element from the cardboard packaging. Tilt the screen backwards. Turn the fastening screw on the screen with a crosstip screwdriver until the connecting part is loosened. Then insert it into the footed stand. Insert the joint of the screen element into the footed stand.
Securing into Place Now fasten the screw on the footed stand into place again using the crosstip screwdriver. Ensure that the screw is in the correct position.
Adjustable Screen Angle Adjustable Screen Angle Adjustable Screen Angle The BA73A is fitted with a joint on the rear. You can optimize the angle of the screen depending on the viewing and lighting conditions. loose tight Use a screwdriver to set the twisting force of the BA73A on the adjusting nut. 90 0 The angle of the screen can be adjusted from a horizontal position to a vertical position to the stop (max. 90°), without any tools.
Ergonomic Terminal Workplace Ergonomic Terminal Workplace Ergonomic Terminal Workplace Please observe the following when setting up your terminal workplace: Avoid direct glaring and reflective glaring. Use the screen only in a controlled luminance surounding. Install the device with a viewing direction that is parallel to the windows. Avoid reflective glaring caused by electric light sources.
Installation Installing the Controller in the BEETLE First ensure that the controller is switched off and the mains supply plug has been pulled out. Remove the housing upwards. Take care in doing so that you do not tilt or jam the housing in any way. If a VGA sandwich module or a VGA controller is installed, remove this board. Mind the measures of electrostatically endangered components.
Installing the Controller in the BEETLE Metal tracks Speaker connector In order to be able to install the LCD-Controller-A, you must first remove the metal panel that covers the free slots by loosening the screw. Set the jumper for the I/O addresses and the interrupt requests on the COM board. It is strictly necessary to avoid conflicts, so please inform yourself of already existing settings. Plug the TFT COM board into the corresponding ISA terminal and plug the LCD-Controller-A into the PCI terminal.
Connecting the Speaker Cable Connecting the Speaker Cable Connecting the Speaker Cable Remove the speaker cable from the BEETLE-CPU by simply unplugging the connector.
