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.
The low-energy, flickerfree and radiation-free colour monitor of the BA72A is an Active-Matrix-Display in TFT-technology (Thin Film Transistor). Therefore, it is especially 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 or fastened to a tubular stand. 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.
BA72A Components Screen Module The screen module represents the main unit of the BA72A. 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 BA72A 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 “Stretching” is only possible when a separate TFT conroller is used. So, when operating with the BA72A and the integrated TFT controller at the Media GXm CPU, “stretching” is not possible. Here you will see a black margin around the centered picture. 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.
TFT-Controller-A TFT-Controller-A TFT-Controller-A The TFT-controller-A is a plug-in-controller with a PCI-interface. There are two connections for H H 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 Pentium CPU, 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 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. The screen does not react in any way if touched, for example, with a pencil or a glove. Brightness and Loudness To adjust the brightness first remove the cable cover on the back of the screen (see p. 4). Set brightness with the thumb wheel left of the socket for the cable.
COM Board COM Board for Touch Screen COM Board The COM Board is an additional board for the TFT-controller-A with an ISA bus interface that has 2 or 4 COM interfaces (COM5, 6, 7, 8). COM5 and COM6 are linked to the BA72 controller via a plug connector. COM5 is a reduced COM interface for RxD and TxD signals and is intended for the use of the (optional) touch function. As an option the COM board can be equipped with a COM7 and a COM8 interface.
COM Board COM Interface Interrupts COM5 COM6 COM7 COM7-8 COM6-8 Interrupt IRQ9 I9 - - - I11 IR9 IRQ10 I10 - - - I12 IR10 IRQ11 I5 - I4 I8 I13 IR11 IRQ12 I1 - - - I6 IR12 IRQ15 I3 I2 - - I14 IR15 For the default setting the jumper I1, I2, I8, IR11, IR12 and IR15 are active (closed). 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.
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 AT 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 (pls.
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. The Wincor Nixdorf PCD product line e. g. is delivered with this type of mouse. Some systems allow to disable the mouse port in the BIOS Setup, e.g. those of the Wincor Nixdorf PCD product line.
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 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. like (only one at a time) - open COM n - use COM n - close COM n - open COM n+1 - use COM n+1 - close COM n+1 etc.
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-MediaGXm LCD-TFT Adapter A-MediaGXm LCD-TFT Adapter A-MediaGXm In the case of the BEETLE with GXm CPU the TFT adapter can be connected with GXm CPU without TFT controller and without COM board. The LCD TFT adapterA is a submodule of the GXm CPU which is necessary for the connecting process. The optional touch function is to be realized internally via the COM2 interface. When applicating the touch function the COM2 interface (D-sub connector on the motherboard) cannot be used.
LCD-TFT Adapter A-Celeron LCD-TFT Adapter A-Celeron LCD-TFT Adapter A-Celeron In the case of the BEETLE with Celeron CPU the TFT adapter can be connected with the Celeron CPU without TFT controller and without COM board. The LCD TFT adapterA is a submodule of the Celeron 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.
Touch Screen Construction of the resistive Touch Screen: Hard-coated polyester topsheet Adhesive Glass substrate with spacer dots How to Operate Touch Screen 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.
Installing and Securing the Screen into Place The screens can be installed either with or without attached operating elements, as a table top terminal or on a tubular stand. Securing into Place Installing the BA72A into Place (Table Top Version) 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.
Tubular Stand Version Tubular Stand Version Now fasten the screw on the footed stand into place again using the crosstip screwdriver. Ensure that the screw is in the correct position. Securing the screen into Place (Tubular Stand Version) The system has been designed for securing into place on a tubular stand, with a tube with 35.2 ± 0.2mm inner diameter. The tube length can be varied. The tube on which the system is secured is not included in the scope of delivery.
