How to Use This Guide 

This manual is designed to help you to use the PCI-9114/9114HR.  It is 
divided into six chapters: 
 

•

 

Chapter 1

, "Introduction," gives an overview of product features, 

applications, and specifications. 

•

 

Chapter 2

, "Installation," describes how to install the PCI-9114.  

The layout of PCI-9114 is shown, and the jumper settings for 
analog input channel configuration are specified.  The connectors 
pin assignments and termination boards connection are 
described.   

•

 

Chapter 3

, "Registers Format," describes the details of registers 

format and structure of the PCI-9114, this information is very 
important for the programmers who want to control the hardware by 
low-level programming language. 

•

 

Chapter 4

, "Operation Theorem" describes how the PCI-9114 

operates. The A/D and timer/counter functions are introduced. Also, 
some programming concepts are specified in this chapter. 

•

 

Chapter   5

, "C/C++ Library" describes high-level programming 

interface. It helps programmer to control PCI-9114 in high-level 
language style. 

•

 

Chapter 6

, "Calibration & Utilities," describes how to calibrate the 

accuracy of PCI-9114, and how to use the utility programs included 
in the software CD.
