Rockwell Automation 1747-PCINT API Software for 1746 I/O - Manual (Page 14)

1–6 Overview
Publication 1747-6.5.3 June 1998
Installing the
Windows NT API To install the Windows NT API, use the setup utility:
1. Insert the API diskette into a diskette drive.
It is recommended that you exit all applications before starting the setup process.
2. Select Run from the startup menu, then select the setup.exe program from the
API diskette.
3. Click on OK to execute the setup utility. Follow the displayed instructions. Click
on Next.
4. The next dialog lets you choose whether to install the API development and
executable files (Complete) or the API executable files (Runtime), or just the
API development files (Development). To develop applications with the API,
you need the development files. To only run applications, only the runtime files
are necessary. The development files consist of an include file, import library,
and sample code. The runtime files consist of a device driver and a dynamically-
linked library.
Important: Runtime files may only be installed on a Windows NT system.
However, the development files may be installed on either
Windows NT or Windows 95 systems.
Choose the appropriate installation option and click on Next.
5. Specify the destination directory and click on Next.
6. The necessary files are copied to the disk, and the system registry is updated to
include the OCdriver information.
7. Choose whether to reboot the system now or later and click on Finish.
Important: You must shutdown and reboot the scanner before using the API. (The
setup utility sets the registry Start parameter for OCdriver to
Automatic; therefore, the service manager starts the OCdriver when
the system is booted.)
The Windows NT API uses these files:
This file: Contains:
ocapi.lib Import library in Microsoft COFF format
ocapi.h API header file that contains API-referenced structures
ocapi.dll API DLL
sample.c Sample application program calling the API functions
sampleb.mak Sample make file for the Borland C compiler
samplem.mak Sample make file for the Microsoft C compiler
