How to Use This Guide
This manual is for helping users to manipulate the PCI-9112 and cPCI-
9112. The functionality of PCI-9112 and cPCI-9112 are the same.
Therefore,the“PCI-9112” in this manual represent both the PCI-9112 and
cPCI-9112 without specifications.
The manual describes how to modify various settings on the PCI-9112
card to meet your requirements. It is divided into seven chapters:
ØChapter 1, Introduction, gives an overview of the product
features, applications, and specifications.
ØChapter 2, Installation, describes how to install the PCI-9112.
The layout of PCI-9112 is shown, jumper setting for analog input
channel configuration, D/A reference voltage settings are specified.
The connectors' pin assignment and how to connect the outside
signal and devices are also described.
ØChapter 3, Registers Format, describes the details of register
format and structure of the PCI-9112, this information is very
important for the programmers who want to control the hardware
by low-level programming.
ØChapter 4, Operation Theorem, describes how to operate the
PCI-9112. The A/D, D/A, DIO and timer/counter functions are
introduced. Some programming concepts are also specified.
ØChapter 5, C/C++ Library, describes the software utility and
library of PCI-9112, and also describes how to install and operate
the utility and library to meet your requirements and help you to
program your own software application.
ØChapter 6, Calibration, describes how to calibrate the PCI-9112
for accurate measurement.
ØChapter 7, Software Utility, describes the software utilities which
can help you to run the card.
