Chapter 6: Software 

 

Included with the TCDA module is a diskette with software 

examples written in Borland C++, Borland Pascal and Microsoft® 
QuickBASIC v4.5. These DOS-based example program show how 
to access the TCDA module connected to the following modules: 
 

 

232SDA10 

 

232SDA12 

 

232SPDA 

 

232SPDACL 

 

485SDA10 

 

485SDA12 

 

485SPDA 

 

485SPDACL 

 

ADIO12 

 

Installation 

To install the example files on your hard drive: 
 

 

Place the disk in drive A. 

 

Type A: and press the <ENTER> key. 

 

Type INSTALL and press the <ENTER> key. 

 

Follow the instructions given by the program. 

 
 

After the software installation is complete, the file, FILES.LST, 

contains a list of installed files with a brief description of each. The 
file, HISTORY.LST, contains a description of each revision to the 
software files. The file, READ.ME, contains corrections and 
additions to the printed documentation. The file, MAKEIT.BAT, in the 
subdirectory for each module is an example of how to compile and 
link the example program in each language. This file may need to be 
modified to use the path to your compiler.
