Important Notes The data cables must not be plugged or unplugged during storms. Repairs to the BEETLE AT COM board should only be carried out by authorized, trained personnel.
WARRANTY All parts of the product which are subject to wear and tear are not included in the warranty engagement. Please order spare parts at the Wincor Nixdorf customer service.
ABOUT THIS MANUAL Introduction The BEETLE AT COM board is a half-length, plug-in board for BEETLE POS systems. The COM board provides you with two additional power-supplied COM interfaces. For the BEETLE /XL, there is the option of another two powersupplied interfaces (a total of 4 additional interfaces). If you have additional COM interfaces, you can connect more peripheral devices to your BEETLE POS system. About this manual This manual describes the BEETLE AT COM Board.
INSTALLATION IN THE BEETLE /XL Installation of COM7 and COM8 If you want to activate the (optional) interfaces COM7 and COM8 first fix the chip (see illustration). Please take care that the position point (terminal) on the chip shows to the back of the board. Then plug the connector of the male/female connectors as shown in the illustration below. Now you can secure the connectors (male/female), which are fitted to a cover, to the marked recess on the housing using the screws provided.
INSTALLATION IN THE BEETLE /60, BEETLE /L Installation in the BEETLE /60, BEETLE /L Install the COM board in a free slot of your BEETLE POS system. Refer to the documentation of your POS system (chapter on installing an expansion card). Installation in the BEETLE /M When installing the At COM board please proceed as described in the manual “BEETLE /M”, chapter “AT plug-in card”. Insert the complete shell with the COM7/COM8 interfaces from outside into the backplane.
I/O ADRESSES I/O Adresses The I/O addresses are adjusted by means of I/O1-I/O3 jumpers.
INTERRUPTS Interrupts The interrupts are also set by means of jumpers. In total there are 15 interrupts (IRQ) in a PC system. The interrupts IRQ1 - IRQ8, IRQ13 and IRQ14 are not available with the AT-COM board because they are internally used. The Retail Device Interface (RDI) supports the interrupts IRQ11, IRQ12 and IRQ15. (For more details please see the README file that is part of the RDI.) For PC application the interrupts IRQ9 and IRQ10 can also be used.
INTERRUPTS Example 1: COM5 to IR9 and COM6 - 8 shared to IRQ10. Plug in jumper I9, IR9, I12 and IR10. Example 2: COM5 to IRQ12, COM6 to IRQ15 and COM7 - 8 shared to IRQ11.
ASSIGNMENT OF COM PORT ADDRESSES Assignment of COM Port Addresses and Interrupts 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.
ASSIGNMENT OF COM PORT ADDRESSES BEETLE systems factory settings provide to use shared IRQ10 for COM3 and COM4, but COM4 can be configured by jumpers on the motherboard to use IRQ11 instead. Some of the new PCs use IRQ11 for USB (Universal Serial Bus). IRQ12, probable conflict Mouse Port or PS/2 Mouse These types of mice are supported e.g. 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.
ADDING COM PORTS Adding COM ports under Windows 9x To add a COM port to your system configuration, run the “Add New Hardware” wizard. It is not recommendable to run the automatic hardware detection! Add the new COM port explicitly instead. You will get some (presumably wrong) port address and IRQ. Change these according to the jumper configuration you set before. After having made these changes to the Windows 9x configuration, you will have to reboot the system, before they can get into effect.
ADDING COM PORTS Using shared interrupts for COM ports with Windows NT Sharing an interrupt for a COM port under Windows NT requires a specific configuration in the Registry. To provide for interrupt sharing the steps are: n Assure that you have permission to change the Registry n Run REGEDIT.EXE or REGEDT32.EXE n In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Serial set the value of the variable ‘PermitShare’ to 1. Add this variable in case it does not exist (DWORD type).
USING SHARED INTERRUPTS Proceed very carefully as wrong entries in the registry could prevent Windows NT from starting! Therefore, you should save your registry before. Hint: ‘PermitShare’ is a variable of Windows NT. Using shared interrupts for COM ports under Windows 9x Under Windows 9x, sharing COM ports does not require special provisions other than correctly configurating the resources used with the Device Manager.
