How to Use This Guide
This manual is designed to help you use the PCI-7200 and cPCI-7200. The
functionality of PCI-7200 and cPCI-7200 are the same except that cPCI-7200
has 4 auxiliary digital input and output. Therefore, the “PCI-7200” represents
both PCI-7200 and cPCI-7200 if not specified.
The manual describes how to modify various settings on the PCI-7200 card to
meet your requirements. It is divided into seven chapters:
uChapter 1, "Introduction," gives an overview of the product features,
applications, and specifications.
uChapter2,"Installation,"describeshowtoinstallthePCI-7200.Thelayout
of PCI-7200 is shown, and the installation procedures, pin assignment of
connectors, and timer pacer generation are specified.
uChapter 3, "Register Structure & Format," describes the low-levelregister
structure and format of the PCI-7200.
uChapter 4, "Operation Theorem," describes how the PCI-7200 works.
uChapter 5, "C/C++ & DLL Library," describes the high level C and DLL
library functions. It will help you to programming in DOS, Win 3.11, and
Win-95 environments.
uChapter 6, "Double Buffer Mode Principle," describes the data buffer for
double-buffered DMA DI operation.
uChapter 7, "Limitation," describes three limitations on using PCI-7200.

Introduction
The PCI-7200/cPCI-7200 is PCI/CompactPCI form factor high-speed digital
I/O card, it consists of 32 digital input channels, and 32 digital output channels.
High performance designs and the state-of-the-art technology make this card
suitable for high-speed digital input and output applications.
The PCI-7200 performs high-speed data transfers using bus-mastering DMA
via 32-bit PCI bus architecture. The maximum data transfer rates can be up to
12MB per second. It is very suitable for interfacing high-speed peripherals and
your computer system.
Several different digital I/O operation modes are supported:
1.Direct Program Control: the digital inputs and outputs can be accessed
and controlled by its corresponding I/O ports directly.
2.Timer Pacer Mode: the digital input and output operations are handled by
internal timer pacer clock and transferred by bus mastering DMA.
3.External Clock Mode:the digital input operations are handled by external
input strobe signal (I_REQ) andtransferred by bus mastering DMA.
4.Handshaking:through REQ signal and ACK signal, the digital I/O data can
have simple handshaking data transfer.

Installation
This chapter describes how to install the PCI-7200. At first, the content of the
package and the unpacking information that you should be careful are
described. Because the PCI-7200 is a plug and play device, there is no more
jumper or DIP switch setting for configuration. The Interrupt number and I/O
port address are assigned by the system BIOS during system boot up.
2.1 What You Have
In addition tothis User's Manual, the package includes the following items:
uPCI-7200 Digital I/O & Counter Card
uInclude ACL-10437: 40-pin to 37-pin D-Sub cable
or
ucPCI-7200 Digital I/O & Counter Module for 3U CompactPCI
uInclude 100-pin SCSI connector assembly
uADLINK CD
uSoftware Installation Guide
If any of these items is missing or damaged, contact the dealer from whom you
purchased the product. Save the shipping materials and carton in case you
want to ship or store the product in the future.

8•Installation
2.2 Unpacking
Your PCI-7200 card contains sensitive electronic components that can be
easily damaged by static electricity.
The card should be done 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 damage. Shipping and handling
may cause damage to your module. Be sure there are no shipping and
handling damages on the module before processing.
After opening the card module carton, extract the system module and place it
only on a grounded anti-static surface component side up.
Again inspect the module for damage. 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 APPLY POWER TO THE CARD IF IT HAS BEEN DAMAGED.
You are now ready to install your PCI-7200.
2.3 Device Installation for Windows Systems
OnceWindows95/98/2000hasstarted,thePlugandPlayfunction ofWindows
system will find the new NuDAQ/NuIPC cards. If this is the first time to install
NuDAQ/NuIPC cards in your Windows system, you will be informed to input
the device information source. Please refer to the “Software Installation
Guide” for the steps of installing the device.
