1. Introduction
PCI-1202/1602/180x Development Toolkit provides DLL (Dynamic Link Library) and
simple DEMOs. Those DEMOs will show you how easy to use DLL to complete the
I/O process without facing complex hardware.
This document introduces PCI-1202, PCI-1602, and PCI-180x series functions
in the DLL. It is intended to be a companion to know functions, using the special
functions (Continuous Capture, MagicScan...), programming, and error code
information.
These DLL can perform a variety of data acquisition operation as follows:
1. Testing function
2. Plag & Play function
3. DIO function
4. DA function
5. AD funciton
6. MagicScan function
7. M_Function
8. Continuous Capture function
9. Batch Capture function
Section 1.1 : Functions categories and define.
Section 1.2 : Error code define.
Section 1.3 : The list of Configuration code that can control amplifier signal.
Section 1.4 : The list of thread priority setting.
(With the priority setting, you can get higher thread priority in the OS.)

1.1 Function Define
When you read the function manual, please notice the "KeyWORD" for variables.
KeyWORD

functions
Set after call functions and return
value

[Output] No Yes
The functions in the PCI-1202 DLL are divided into 9 categories. (The red WORD
"P1202" of functions name could be replaced with "P1602" or "P180x" to use the
functions which have the same purpose defined in P1602 or P180x DLL.)
