2.4 Hardware Installation PCI configuration The PCI cards (or CompactPCI cards) are equipped with plug and play PCI controller, it can request base addresses and interrupt according to PCI standard. The system BIOS will install the system resource based on the PCI cards’ configuration registers and system parameters (which are set by system BIOS). Interrupt assignment and memory usage (I/O port locations) of the PCI cards can be assigned by system BIOS only.

CompactPCI Installation Procedures 1. Read through this manual, and setup the jumper according to your application. 2. Turn off your computer and turn off all accessories computer. connected to 3. Remove the slot cover from the CompactPCI. 4. Select a 32-bit CompactPCI slot on the back plane for cPCI-7248 board. Select a 32-bit CompactPCI slot with rear I/O extension for cPCI-7249R. 5. Before handling the boards, discharge any static buildup on your body by touching the metal case of the computer.

2.7 Jumpers Description The 7248/96 DIO cards are ‘plug-and-play’, thus it is not necessary to setup the card configurations to fit the computer system. However, to fit users’ versatile operation environment, there are still a few jumpers to set the power-on status of ports and the usage of the +12V output pins. 2.7.1 Power on Status of Ports For every port on the 7248/96 cards, the power-on status is set as input, therefore, the voltage could be pulled high, pulled low, or floating.
PAGE 26
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 the 12V power are for CN1~CN4 respectively. Connections with ground are set as default. The following diagram shows the setting of JP2, connecting the pin 2 and pin 4 of CN2 to ground. (12V)1 2.

3 Registers Format The detailed descriptions of the registers format are specified in this chapter. This information is quite useful for the programmers who wish to handle the card by low-level programming. However, we suggest user have to understand more about the PCI interface then start any low-level programming. In addition, the contents of this chapter can help users understand how to use software driver to manipulate this card. 3.

4 Operation Theorem 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.
PAGE 31
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. Here we define the port name in Table 4.1. These port names are used both in software library and all through this manual. The programming for PCI-7224/7248/7296 and cPCI-7248 are fully compatible.

4.2 Timer/Counter Operation 4.2.1 Introduction One 8254 programmable timer/counter chip is installed in 7248/96 series. There are three counters in one 8254 chip and 6 possible operation modes for each counter. The block diagram of the timer /counter system is shown in Figure 4.2. P1C4 Trigger Edge Control 2 MHz Clock 8254 Chip C 'H' Counter #0 O Timer #1 O Timer #2 O Event IRQ G C 'H' G C Timer IRQ 'H' G Figure 4.2 Timer/counter system of 7248/96 series.
PAGE 34
The 8254 timer/ counter IC occupies 4 I/O address. 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 or 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. The output of the timer is send to the interrupt circuit (refer to section 4.3).
PAGE 35
4.3.2 IRQ Level Setting There is only one IRQ level requested by this card, although it is a dual interrupt system. The mother board 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. Users can get the IRQ level setting by software library. INT1 INTA# PCI Controller INT2 IRQ FlipFlops INT1 MUX P1C0 ~P1C0 & P1C3 Event Counter INT2 MUX P2C0 (*) ~P2C0 & P2C3 (*) Timer IRQ Clear IRQ Fig 4.
PAGE 36
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 need only one IRQ, you can disable one of the IRQ sources by software. If your application do not need any IRQ source, you can disable both interrupts. However, the PCI BIOS still assign a IRQ level to the PCI card and occupy the PC resource, if you only disable the IRQ sources without change the initial condition of the PCI controller.
PAGE 37
4.4 12V and 5V Power Supply The OPTO-22 compatible connectors provide external devices the +12 volts and +5 volts power supply. To avoid short or overload of the power supply, the resetable fuses are added on all the output power. Refer to Figure 2.6.1 The maximum current for 5 volts on every connector is 0.5 A. If the load current is larger than 0.5 A, the resistance of resetable fuse will increase because of the rising temperature.

5 C/C++ Libraries This chapter describes the software library for operating these card. Only the functions in DOS library and Windows 95 DLL are described. Please refer to the PCIS-DASK function reference manual, which included in ADLINK CD, for the descriptions of the Windows 98/NT/2000 DLL functions. The functions of PCI-7248 can also be applied to PCI-7224 and cPCI-7248. Therefore, in the following section, there is no special functions for PCI-7224 and cPCI7248.
