2 Installation This chapter describes how to install the 24H/48H/96H series products. At first, the contents in the package and unpacking information that you should be careful of are described. l l l l l l l l 2.1 Check what you have (section 2.1) Unpacking (section 2.2) Check the PCB (section 2.3) Hardware installation (section 2.4) Device Installation for Windows System (section 2.5) Connector pin assignment (section 2.6) Jumpers setup (section 2.7) Termination boards connection (section 2.
2.2 Unpacking Your card contains sensitive electronic components that can be easily damaged by static electricity. The card should be put on a grounded anti -static mat. The operator should wear an anti -static wristband, grounded at the same point as the anti -static mat. Inspect the card module carton for obvious damage. Shipping and handling may cause damage to your module. Be sure there is no shipping and handling damage on the module before processing.

2.4 Hardware Installation PCI configuration The PCI cards are equipped with a plug and play PCI controller, it can request base addresses and interrupts in accordance with the 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.
2.5 Device Installation for Windows Systems Once Windows 95/98/2000/XP h a s started, the Plug and Play function of Windows system will find the new PCIDAQ cards. If this is the first time you're installing a PCIDAQ card in your Windows system , you will be prompted to input the device information source. Please refer to the “Software Installation Guide” for the steps of installing the device.
2.6 Connector Pin Assignment 2.6.1 Pin Assignment of PCIDIO 24H/48H/96H The I/O ports of PCIDIO 24H/48H/96H emulate the mode 0 configuration of the 8255 general purpose programmable peripheral interface. The cards come equipped with 50-pin male IDC connectors that interface with OPTO22. Figure 2.4 shows the circuits and pinout of PCIDIO 24H/48H/96H's connectors (CN1~CN4) .
2.6.1 Continued Figure 2.6.1 pin assignments and pow er signals of PCIDIO 24H/48H/96H The DIO pin names are specified as PnXb, where n : means the connector reference number n=1~4. X : means the port name, X= ‘A’ , ‘B’ or ‘C’ b : means the bit number of a port, b=0~7 For example, P1C4 means bit 4 of port C on connector CN1. Note: 1. The pinout of the CN1 ~ CN4 connectors are identical. 2. The power supply pins are protected by resetable fuses. Refer to section 4.4 for details of the power supply.

2.7 Jumpers Description The 48H/96H 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 PCIDIO 48H/96H cards, the power-on status is set as input, therefore, the voltage could be pulled high, pulled low, or floating.
2.7.2 12V Power Supply Configuration 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 Detailed descriptions of the register's format are specified in this chapter. This information is quite useful for the programmers who wish to handle the card through low-level programming. However, we suggest users understand more about the PCI interface before beginning any low-level programming. In addition, the contents of this chapter can help users understand how to use a software driver to manipulate this card. 3.
3.2 I/O Address Map All the 48H registers are 8 bits. The users can access these registers only by 8 bits I/O instructions. The following ta ble shows the registers map, including descriptions and their offset addresses relative to the base address. Please refer to the chapter 4 for more detailed operation of every registers.
4 Operation Theorem 4.1 Digital I/O Ports 4.1.1 Introduction The 48H/96H 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.
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 PCIDIO 24H/48H and PCIDIO 96H are fully compatible.

4.2 Timer/Counter Operation 4.2.1 Introduction One 8254 programmable timer/counter chip is installed in 48H/96H 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 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 48H/96H series.
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).
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. 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.
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 doesn't need any IRQ source, you can disable both interrupts. However, the PCI BIOS still assigns an IRQ level to the PCI card and occupies the PC resource if you only disable the IRQ sources without changing the i nitial condition of the PCI controller.
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, resetable fuses are added on all the output power. Refer to Figure 2.5. 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. The rising resistance will cause the power supply drop and reduce current.
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 PCI DASK function reference manual, which is included with the CD, for the descriptions of the Windows 98/NT/2000/XP DLL functions. The functions of PCIDIO 48H can also be applied to PCIDIO 24H. Therefore, in the following section, there are no special functions for the PCIDIO 24H.
5.2 Programming Guide 5.2.1 Naming Convention The functions of the PCIDAQ PCI cards' software driver use full-names to represent a function's real meaning. The naming convention rules are: In DOS Environment: _{hardware_model}_{action_name}. e.g. _DIO48H_Initial(). All functions in the PCIDIO 48H driver are used by the board as {hardware_model}. But they can be used by PCIDIO 48H and PCIDIO 24H.
5.3 _DIO48H/96H_Initial @ Description The cards are initialized by this function. The software library could be used to control multiple cards.
5.4 Digital Input @ Description This function is used to read 8-bit digital input data from digital input ports. You can get the 8 -bit data from _DIO48H_DI by using this function. The written data and read in data is 8 -bit data. Each data is mapped to a signal as the table below.
