How to Use This Guide
This manual is designed to help you use the 9116 series. The manual
describes how to modify various settings on the card to meet your
requirements. It is divided into seven chapters:
Chapter1, “Introduction”, gives an overview of the product features,
applications, and specifications.
Chapter 2, “Installation”, describes how to install the 9116 series.
The layout of 9116 series is shown.
Chapter 3, “Signal Connection”, describes the connectors' pin
assignment and how to connect external signal and devices
to the9116 series card.
Chapter 4, “Registers”, describes the details of the registers and its
structure. This information is important for programmers who
want to control the hardware with low-level programming.
Chapter 5, “Operation theory”, describes the working theory of the
9116 series card. The A/D, DIO and timer/counter
functions are introduced. Also, some programming concepts
are specified.
Chapter 6, “Software Utility & Calibration”, describes how to run the
utility program included in the software CD and how to
calibrate the9116 series card for accurate measurements.
