The API software for the 1746 I/O PCI Interface is compatible with the API for the
1747 Open Controller. The sample code and header files contain comments and
functions that are supported by the Open Controller but not supported by the 1746
I/O PCI Interface. The following table lists the differences between the Open
Controller and the 1746 I/O PCI Interface.
Important: All references to Open Controller in the example code or header files
apply to the 1746 I/O PCI Interface.
