Figure 2-8: R7249 OPTO-22 Connectors Pin Assignment Note: The power supply pins are protected by resettable fuses. Refer to section 3.7 for details of the power supply.
72XX Series User’s Manual 2.7 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. 2.7.
72XX Series User’s Manual The physical meaning of all the jumpers are identical. The poweron status of each port can be set independently. The default is to pull all signals high. The following diagram use JA1 as an example to show the possible configurations. 1. Port A of CN1 are power-on pulled high. ‘H’ 1 2 JA1 2. Port A of CN1 are power-on pulled low. ‘L’ 1 2 JA1 3. Port A of CN1 are power-on floating (The jumper is removed) 1 2.7.

72XX Series User’s Manual 3 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. In addition, the contents of this chapter can help the user understand how to use the software driver to manipulate this card. 3.
72XX Series User’s Manual 3.2 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.
72XX Series User’s Manual 4 Operation Theory 4.1 Digital I/O Ports 4.1.1 Introduction The 7248/96 products can emulate one/two/four mode 0 configuration of 8255 programmable peripheral interface (PPI) chips. There are 24 DIO signals for every PPI. 4.1.
72XX Series User’s Manual 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. The programming for PCI-7224/7248/7296, PCIe-7248/7296, and cPCI7248 are fully compatible.
72XX Series User’s Manual 4.1.5 Control Word The control word written in the control port is used to setup PA, PB, and PC as input or output port. Figure 4.1 shows the format of the control word. Table 4.2 shows the 16 possible control words and the respective I/O configurations.
72XX Series User’s Manual 4.1.6 Power On Configuration The default configuration after power on, hardware reset, or software reset sets all ports as input ports. Therefore, users do not need to worry about damaging external devices when system is on. In addition, the default signal level can be pulled high or pulled low by setting the jumpers. Refer to section 2.7 for setting the power on status of the DIO ports. 4.1.
72XX Series User’s Manual 4.2 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. P1C4 Trigger Edge Control 8254 Chip C Event IRQ Counter #0 O Timer #1 O Timer #2 O 'H' G 2 MHz Clock C 'H' G C Timer IRQ 'H' G Figure 4-2: Timer/counter system of 7248/96 series.
72XX Series User’s Manual 4.2.2 General Purpose Timer/Counter The counter 0 is a general purpose timer/counter for users applications. It can be used as an event counter, for measuring frequency, or other functions. The following Modes are provided by the 82C54 chip.
72XX Series User’s Manual 4.3 Interrupt Multiplexing 4.3.1 Architecture The 7248/96 series products have a powerful and flexible interrupt multiplexing circuit which is suitable for many applications. The board is capable of accepting Dual Interrupts. The dual interrupt means that the hardware can generate two interrupt request signals at the same time and the software can service these two request signals by ISR. Note that the dual interrupts do not imply the card occupies two IRQ levels.
72XX Series User’s Manual 4.3.3 Note for Dual Interrupts The PCI controller of PCI-7224/7248/96 can receive two hardware IRQ sources. However, a PCI controller can generate only one IRQ to PCI bus, the two IRQ sources must be distinguished by ISR of the application software if the two IRQ are all used. The application software can use the “_72xx_Get_Irq_Status” function to distinguish which interrupt is inserted.

72XX Series User’s Manual 4.4 12V and 5V Power Supply 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.
72XX Series User’s Manual 5 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. Therefore in the following section, there are no special functions for PCI-7224 and cPCI7248.
72XX Series User’s Manual 5.2 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.
