All functions in the OptoPM32.dll return an error value. A non-zero value indicates an error has
occurred. For proper application operation, make sure your program checks error codes. See the list
of error codes on
Use the following basic steps in your application (in Visual Basic or Visual C++):
1. Open a handle to the board using the function PamuxPCICardOpen.
2. Inspect the error code of the device open function.
3. Configure the direction of the points.
4. Start the application loop that continuously reads or writes points. At the same time, continue
5. When the application loop is complete, close the handle to the board using
Special Directions for Visual Basic Programmers
Include the OptoPM32.bas file as a module in your project. This file includes subroutine declarations,
function declarations, and access paths to the OptoPM32.dll.
These files may be found in the toolkit under \Vb\VB dll header.
Special Directions for Visual C++ Programmers
Include the header OptoPM32.h in your source code modules that reference the OptoPM32.dll
functions. Also include the DLL link library OptoPM32.lib in your project so the DLL references are
