It describes how to modify and control various functions of the 743X card to meet the requirements of your application. It is divided into four chapters: Chapter 1, “Introduction”, gives an overview of the product features, applications, and specifications. Chapter 2, “Getting Started”, describes how to install the board. The PCB layout, connector specifications, and installation notes are also described.
1 Introduction The 743X series products are 64-CH high-density isolated digital input and/or output cards. The 743X series products include the following cards and are available in different form factors.
The above I/O cards are isolated up-to 5000 Vdc (excluding cables) for channel-to-computer isolation. It protects your computer against damage caused by accidental contact with high external voltage and eliminates troublesome ground loops. The 743X series products use PCI-9050 PCI controller to interface the board to the PCI bus. The PCI-9050 fully implements the PCI local bus specification Rev 2.1.

2 Getting Started This chapter describes how to install and setup the 743X Series cards. The contents in the package and unpacking information that you should be aware of are outlined first. 2.
2.2 Unpacking The PCI-7432/33/34 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. Shipping and handling may cause damage to your module. Be sure there are no shipping and handling damages on the modules carton before continuing.
2.3.2 cPCI-743X PCB Layout The CN1 is the I/O interface and is a 100-pin SCSI-type connector. Figure 2: 2.3.3 cPCI-743X PCB Layout cPCI-743XR PCB Layout CN1 is the I/O interface and is a 100-pin SCSI-type connector. J2 is used for rear I/O signaling. There are no connectors on the main board.
2.4 Hardware Installation Outline PCI configuration The PCI cards (or CompactPCI cards) are equipped with plug and play PCI controllers, it can request base addresses and interrupts according to the PCI standard. The system BIOS will assign the system resources based on the PCI cards’ configuration registers and system parameters (which are set by the system BIOS). Interrupt assignment and memory usage (I/O port locations) can only be assigned by the system BIOS.
For cPCI-743X products (with and without rear I/O) 1. Read through this manual, and setup the jumper according to your application needs. 2. Turn off your computer and all accessories (printer, modem, monitor, etc.) connected to the computer. 3. Remove the cover from the slot of your cPCI computer. 4. Select a 32-bit cPCI expansion slot on the back plane for cPCI-743X card. 5.

2.11 Jumpers Setting Digital I/O cards often operate in noisy environments and may suffer electrostatic discharge or transient voltage up to several 1000 volts. To protect the system from potential damage, the PCI-7433 have implemented protection circuits on its input channels. Eight jumpers on the PCI-7433 are used to enable or disable the transient voltage suppressors. Each jumper is responsible for up to 8 digital input channels. The following table and figure illustrates the jumper settings.

3 Registers The descriptions of the registers and structure of the 743X Series are outlined in this chapter. The information in this chapter will assist programmers, who wish to handle the card with low-level programs. In addition, the low level programming syntax is introduced. This information can help beginners to operate the 743X in the shortest possible time. 3.1 PCI PnP Registers This PCI card functions as a 32-bit PCI target device to any master on the PCI bus.
3.2 I/O Address Map All 743X series registers are 32 bits long. Users can access these registers using 32-bit I/O instructions.
3.3 Digital Input Register There are 32 isolated digital input channels on the PCI-7432 and 64 isolated digital input channels on the PCI-7433, each bit of based address corresponds to a signal on the digital input channel.
3.4 Digital Output Register There are 32 digital output channels on the PCI-7432 and 64 isolated digital output channels on the PCI-7434, each bit of based address corresponds to a signal on the digital output channel.
4 Operation Theory 4.1 Isolated Digital Input Channels The isolated digital input has an open collector transistor structure. The input voltage range is 0V to 24V (0V to 50V for PCI-7433) and the input resistance is 2.4KΩ (4.7KΩ for PCI-7433). The connection between external signals and the 7432/33 is shown in Fig 12. Please note that the input common junction could be common ground or common power, they are dependent on the user’s environment.
4.2 Isolated Digital Output Channels The common ground connection of isolated digital output is shown figure 13, while common power connection of isolated digital output as figure 14. When the isolated digital output goes “ON”, the sink current will be conducted through the transistors. When the isolated digital output goes “OFF”, no current is conducted flow through the transistors.
5 C/C++ Libraries This chapter describes the software libraries for operating this card. Only the functions in the DOS library and Windows 95 DLL are described. Refer to the PCIS-DASK function reference manual, which is included in the ADLINK CD, for descriptions of Windows 98/NT/2000 DLL functions. The function prototypes and useful constants are defined in the header files located in the LIB directory (DOS) and INCLUDE directory (Windows 95).
5.2 Programming Guide 5.2.1 Naming Convention The functions of the NuDAQ PCI or NuIPC CompactPCI card software drivers uses full-names to represent the functions' real meaning. The naming convention rules are: In DOS Environment : _{hardware_model}_{action_name}. e.g. _7432_Initial(). All functions in the PCI-7432 driver have 7432 as {hardware_model} and can be used by both PCI-7432 and cPCI-7432. All functions in the PCI-7433 driver have 7433 as {hardware_model}.
5.3 Running the Testing Utility After installation, execute the DOS utility by typing the following command: C> cd \7432\DOS\UTIL C> 7432UTIL (Use 7433UTIL.EXE or 7434UTIL.EXEdepending on the model of your 743X series card). 5.4 Initial @ Description The 743X cards are initialized by this function. The software library could be used to control multiple 743X cards.
PCI-7434 / cPCI-7434 / cPCI-7434R C/C++ (DOS) U16 _7434_Initial (U16 *existCards, PCI_INFO *pciInfo) C/C++ (Windows 95) U16 W_7434_Initial (U16 *existCards, PCI_INFO *pciInfo) Visual Basic (Windows 95) W_7434_Initial (existCards As Integer, info As PCI_INFO) As Integer @ Argument existCards : The number of installed 7432/33/34 cards. The returned value shows how many 7432/33/34 cards are installed in the system.
