    Getting Started This chapter describes how to install and setup the PCI-7258. The contents in the package and unpacking information that you should be aware of are outlined first. What you have In addition to the User’s Manual, the package should include the following...

  • Page 16: Unpacking

    Unpacking The card contains electro-static sensitive components that can be easily be damaged by static electricity. Therefore, the card should be handled on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat. Inspect the card module carton for obvious damages.

    PCB Layout The location of the connectors and switches on the PCI-7258 are shown in figure 1 below. Descriptions are o utline in the proceeding sections. Figure 1: PCI-7258 PCB Layout Getting Started 9...
  • Page 18 Figure 2: PCI-7258 External LED connector The PCI-7258 card is designed with 32 LEDs, each indicating the operation status of the 32 relays. In addition, there are also 32 external LED connectors available for users’ to use as so pleases. Utilizing the external LEDs connecting to JP1 or JP2, users can have a visual status of each relay displayed on a chassis, panel or on any apparatus.

  • Page 19: Board Id

    Board ID When two or more data acquisition cards are installed in a system, it can be tedious trying to identify a specific card. For easier identification, the PCI- 7258 implemented a Board ID function. By setting the Dipswitch located at S1, users can assign an ID address to a specific card and access the card through software programming.

  • Page 20: Connector Pin Assignments

    Connector Pin Assignments The PCI-7258 card is equipped with a 68-pin SCSI connector (CN1). Figure 3 defines the pin assignment for the connector. NO18 COM1 COM18 NO19 COM2 COM19 NO20 COM3 COM20 NO21 COM4 COM21 NO22 COM5 COM22 NO23 COM6...

    The available termination board for the 68-pin SCSI connector is the DIN- 68S/1S. The DIN-68S/1S is a general-purpose 68-pin screw terminal with a DIN socket. It is also equipped with a 68-pin SCSI cable that allows for easy installation of the PCI-7258. Getting Started 13...

  • Page 23: Registers

    However, we suggest users to have an understanding of the PCI interface before starting any low-level programming. I/O Address Map The PCI-7258 registers are all 16-bits long. Users can access these registers by 16-bit I/O instructions only. The controls for the relays and status of the isolated inputs are by means of accessing these registers.

  • Page 24: Relay Output Control Register

    Relay Output Control Register There are 32 PhotoMos relays on the PCI-7258; each bit of the register corresponds to a relay channel. Writing “1” to the register will cause the relay to close and “0” will cause it to open.

  • Page 25: Relay Output Read Back Register

    Relay Output Read Back Register The status of the PhotoMos relay can be read back from the readback register. If the relay is in the close position, the corresponding bit value is ‘1’. If the relay is open, then the bit value is ‘0’. Address: BASE + 0x00 Attribute: Read RBK8...

  • Page 26: Isolated Digital Input Register

    Isolated Digital Input Register There are 2 isolated input channels on PCI-7258 card. The status of the 2 channels can be read from the isolated input register. Each bit corresponds to each channel. A “1” means the input logic is high and “0” means the input logic is low.

  • Page 27: Handling Pci Controller Registers

    PCI bus. When users want to develop their own interrupt function driver, both interrupt registers in the PCI- 9030 and in PCI-7258 have to work together. For more information about the interrupt control register in the PCI-9030, refer to the PCI-9030 data book.

  • Page 28: Operation Theory

    Operation Theory PhotoMos Relay Output The PhotoMos relay has LED inputs and MOSFET outputs that provide input- output isolation. When a signal current flows into the LED input pin, the emitted light from the LED is detected by the photoelectric element (solar cell), which is mounted opposite to the LED.
  • Page 29 Furthermore, dithering problems is eliminated. The PCI-7258 is equipped with 32 PhotoMos relays, which are all form A type. The load voltage can either be AC or DC. The basic wiring diagram is shown in figure 5 below.

  • Page 30: Isolated Digital Input

    0 to 24V. Interrupt Architecture PCI-7258 has a powerful dual interrupt routing scheme and t h e interrupt sources are on the digital input channels 0 and 1. Using these interrupts will make handling complicated digital information much easier and relief your computer from the heavy burden of dealing with digital input data.

  • Page 31: C/C++ Dos Libraries

    The functions of the NuDAQ PCI or NuIPC CompactPCI card software drivers uses full-names to represent the functions' real meaning.

  • Page 32: Data Types

    Data Types We have defined some data types in the ACL_PCI.h header file. These data types are used by the NuDAQ Cards’ library. We suggest you use these data types in your application programs. The following table shows the data type names and their range.

  • Page 33: 7258 Initial

    @ Description The PCI-7258 cards are initialized according to the card number. Because the PCI-7258 is designed with the PCI bus architecture and meets the plug and play specifications, the IRQ and base_address (pass-through address) are assigned by system BIOS directly. Every PCI-7258 card has to be initialized by this function before using any other functions.
