  • Page 27: Jumpers Description

    Jumpers Description The 7248/96 DIO cards are Plug and Play, thus it is not necessary to set up the card configurations to fit the computer system. However, to fit different users’ versatile operating environment, there are still a few jumpers to set the power-on status of ports and the usage of the +12V output pins.

  • Page 28: Power Supply Configuration

    2.7.2 12V Power Supply Configuration The pin 2 and pin 4 of the CN1-CN4 50-pin OPTO-22 connectors can be configured as 12V power supply or ground. Please refer to Figure 2.4 for the 12 volts power supply position. JP1-JP4 of 12V power are for CN1-CN4 respectively.

  • Page 31: Chapter 3 Registers Format

    Registers Format The detailed description of the registers format are specified in this chapter. This information is useful for the programmers who wish to handle the card by low-level programming. However, it is strongly recommended that the user has a more in depth understanding of the PCI interface before starting any low-level programming.

  • Page 32: I/O Address Map

    I/O Address Map All the 724X registers are 8 bits. The users can access these registers only by 8 bits I/O instructions. The following table shows the registers map, including descriptions and their offset addresses relative to the base address. Please refer to chapter 4 of this manual for a more detailed description on the operation of different registers.

There are 24 DIO signals for every PPI. 4.1.2 8255 Mode 0 The basic functions of 8255 mode 0 are: Two 8-bit I/O ports-port A (PA) and port B (PB) Two nibble-wide (4-bit) ports C-PC upper and PC lower Each port can be used as either input or output...

  • Page 34: Digital I/O Port Programming

    4.1.4 Digital I/O Port Programming Users can write the digital output value to or read back the digital signal level from the PPI ports by using the software library. The port names are defined in Table 4.1. These port names are used throughout this manual as well as in the software library.

Therefore, users do not need to worry about damaging external devices when system is on.

  • Page 36: Timer/Counter Operation

    Timer/Counter Operation 4.2.1 Introduction One 8254 programmable timer/counter chip is installed in the 7248/96 series. There are three counters in one 8254 chip and six possible operation modes for each counter. The block diagram of the timer/counter system is shown in Figure 4.2.

  • Page 37: Cascaded 32 Bits Timer

    The 8254 timer/counter IC occupies four I/O addresses. Users can refer to Tundra's or Intel®'s data sheet for a full description of the 8254 features. You can download the 8254 data sheet from the following web site: http://support.intel.com/support/controllers/peripheral/231164.htm http://www.tundra.com (for Tundra’s 82C54 datasheet) 4.2.2 Cascaded 32 Bits Timer The input clock frequency of the cascaded timers is 2MHz.

  • Page 38: Irq Level Setting

    4.3.2 IRQ Level Setting There is only one IRQ level requested by this card, although it is a dual interrupt system. The motherboard circuits will transfer INTA# to one of the PC IRQ levels. The IRQ level is set by the PCI Plug and Play BIOS and saved in the PCI controller.

  • Page 39: Interrupt Source Control

    4.3.4 Interrupt Source Control In ISC register (offset 0x20), there are four bits to control the IRQ sources of INT1 and INT2. If the application requires only one IRQ, one of the IRQ sources can be disabled by software. If no IRQ source is required, both interrupts can be disabled.
  • Page 40 The OPTO-22 compatible connectors provide external devices for +12V and +5V power supply. To avoid shorting or overloading the power supply, the resettable fuses are added on all the output power. Refer to Figure 2.6.1 The maximum current for 5V on every connector is 0.5A. If the load current is larger than this, the resistance of the resettable fuse will increase due to the rise in temperature.

  • Page 41: Chapter 5 C/C++ Libraries

    C/C++ Libraries This chapter describes the software library for operating this card. Only the functions in DOS library and Windows 95 DLL are described. A description of Windows 98/NT/2000 DLL functions can be found in the PCIS-DASK function reference manual located in the ADLINK CD. The functions of PCI-7248 can also be applied to PCI-7224 and cPCI-7248.

  • Page 42: Programming Guide

    Programming Guide 5.2.1 Naming Convention The functions of the NuDAQ PCI cards or NuIPC CompactPCI cards’ software driver use full-names to represent the functions' real meaning. The naming convention rules are: In DOS Environment: _{hardware_model}_{action_name}. e.g. _7248_Initial() . All functions in PCI-7248 driver are with 7248 as {hardware_model}. But they can be used by PCI-7248, PCI-7224 and cPCI-7248.
