PCI-AC51 User’s Guide
The PCI-AC51 toolkit comes on a CD with the card. If you do not have the CD, you can order it
through Product Support, or you can download the toolkit free from our Web site,

Required Function Calls
For many applications, only four Pamux functions are required:
1. Open a PCI-AC51 to get a handle.
2. Configure outputs.
3. Read and write to I/O.
4. Close the PCI-AC51 when the application is about to end.
Naming Conventions
Function names in the Pamux library start with “Pamux.” Example: “PamuxDigPointRead.”
Function names follow the object-operation format, with the object first and the operation second.
Example: “PamuxDigPointRead,” where “PamuxDigPoint” (the object) is first and “Read” (the
operation) follows.
Utility functions, provided primarily for Visual Basic, start with “PamuxUtil.” Example:
“PamuxUtilBitEqual.”
Specific PCI-AC51 functions start with “PamuxPCI.”
Banks and Points
Some I/O points can be addressed in multiple ways. A 16-channel I/O board has two banks.
Point 0, the first point, is accessed using a bank number of 0 and a point number of 0. Point 8 can be
accessed in two ways:
•
•
A bank number of 0 and a point number of 8, or
A bank number of 1 and a point number of 0.
