Overview
Introduction
This chapter provides an overview of the 1746 I/O PCI Interface and
the API software. This chapter also describes how to install the API.
You should have one of the following APIs:
•
API for DOS (catalog number 1747-PCIDOS or 1747-OCAPID)
•
API for Windows NT (catalog number 1747-PCINT or
1747-OCAPINT)
The API software license agreement allows you to freely distribute the
executable.
Relationship to the
Open Controller
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 1747-OCF Open
Controller and the 1746 I/O PCI Interface.
Open Controller (1747-OCF)
1746 I/O PCI Interface (1746-PCIS)
