8 • Getting Started

2.2 Unpacking

The PCI-7432/33/34 card conta ins 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.

After opening the card module carton, ext ract the system module and place
it only on a grounded anti-static surface with component side up.

Again, inspect the module for damages. Press down on all the socketed IC's
to make sure that they are properly seated. Do this only with the module
place on a firm flat surface

Note: DO NOT ATTEMPT TO INSTALL A DAMAGED BOARD IN THE

COMPUTER.

You are now ready to install your card.

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. These system
resource assignments are done on a board-by-board basis. It is not
suggested to assign the system resource by any other methods.

PCI slot selection

The PCI card can be inserted into any PCI slot without any configuration of
the system resources. The CompactPCI card can also be inserted into any
CompactPCI I/O slot.

Installation Procedures

1. Turn off your computer

2. Turn off all accessories (printer, modem, monitor, etc.) connected to
your computer.

3. Remove the cover from your computer.

4. Setup jumpers on the PCI or CompactPCI card.

5. Select a 32-bit PCI slot. PCI slot are shorter than ISA or EISA slots,
and are usually white or ivory.

6. Before handling the PCI cards, discharge any static buildup on your
body by touching the metal case of the computer. Hold the edge and
do not touch the components.

7. Position the board into the PCI slot you selected.

8. Secure the card in place at the rear panel of the system.

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 fo r up to 8 digital input channels. The following table and figure
illustrates the jumper settings. Please note that these setting are only
available for the PCI -7433.

Jumper Isolated digital input channel

J1 0 ~ 7
J2 8 ~ 15
J3 16 ~ 23

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. There are three types of registers: PCI Configuration Registers
(PCR), Local Configuration Registers (LCR) and 743x series registers.

The PCR, which is PCI-bus specifications compliant, is initialized and
controlled by the plug & play (PnP) PCI BIOS. Users may obtain more
information on the PCI BIOS specification to better understand the operation
of the PCR. Please conta ct PCISIG to acquire the specifications of the PCI
interface.

The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more information about the LCR, please visit PLX
technology’s web site to download relative information. It is not necessary
for users to fully understand the details of the LCR if the software library
provided is used. The PCI PnP BIOS assigns the base address of the LCR.
The assigned address is located at an offset of 14h from the PCR.

The 743x series registers are discussed in the next section. The base
address, which is also assigned by the PCI PnP BIOS, is located at an offset
of 18h from the PCR. Therefore, users can read the address 18h from the
PCR to obtain its base address by using the BIOS function call. Do not
attempt to modify the base address and interrupt that have been assigned
by the PCI PnP BIOS, it may cause resource conflicts with your system.

3.2 I/O Address Map

All 743X series registers are 32 bits long. Users can access these registers

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. Therefore, the digital input could be either a current
source or a current sink.

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. Please note that
when the load is of an “inductance nature” such as a relay, coil or motor, the
VDD pin must be connected to an external power source. The extra
connection is utilized for the ‘fly-wheel diode’ to form a current-release
closed loop, so that the transistors are protected from any high reverse
voltage which can be generated by the inductance load when the output is
switched from “ON” to “OFF”.

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).
For Windows 95 DLL, the developing environment can be Visual Basic 4.0
or above, Visual C/C++ 4.0 or above, Borland C++ 5.0 or above, Borland
Delphi 2.x (32-bit) or above, or any Windows programming language that
allows calls to a DLL.

5.1 Libraries Installation

Refer to the “Software Installation Guide” for information regarding software
installation of libraries for DOS, Windows 95 DLL, or PCIS-DASK for
Windows 98/NT/2000.

The device drivers and DLL functions for Windows 98/NT/2000 are included
in the PCIS-DASK. Refer to the PCIS-DASK user’s guide and function
reference, which is included in the ADLINK CD, for programming information.

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}. And again can be used by PCI-7433,
cPCI-7433 and cPCI -7433R. All functions in the PCI-7434 driver have 7434
as {hardware_model}. And can be used by PCI-7434, cPCI-7434 and cPCI­7434R.

In order to recognize the difference between the DOS library and Windows
95 library, a capita l "W" is placed at the start of each function name for
Windows 95 DLL drivers. e.g. W_7432_Initial().

5.2.2 Data Types

We have defined some data types in the Pci_743X.h (DOS) and Acl_pci.h
(Windows 95) header files. These data types are used by the NuDAQ Cards’
library. We recommend you use these data types in your application
programs. The following table shows the data type names and their range.

Type

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. Because the 743X is
designed with the PCI bus architecture and meets the plug and play
specifications, the IRQ and I/O address are assigned by the system
BIOS directly
