CHAPTER

: INTRODUCTION
Because the Distribution Software arrives in compressed form, it is important that you follow the
installation instructions in Section 2.4. You must use the installation program to uncompress these
files before you can access FILES.DOC.
The driver software supports the
Pop-up Control Panel
and the Cull Driver, which are two of the three
interface options available for controlling the ADC-16. The third control interface is
Register-Level
I/O
programming. Chapter 3 describes of each of these interfaces.
Additional programming options are available in the Advanced Software Option (ASO)
,
which includes
the File I/O Command Driver, the Call Driver for C and Pascal, and the Dynamic Link Library for
Windows 3.X languages. Contact the manufacturer for information on this option.
NOTE:
The README.DOC file (in the Distribution Software), contains last-minute information
not included in this manual. READMEDOC is a readable ASCII file.
