The SW800 Series of Windows and DOS Drivers are software packages that provide subroutine calls to access the I/O functions of the RTI-800 Series of Analog and Digital boards. There are four hardware-specific packages. Each package includes support for high level languages in both Windows and DOS. (See list of supported languages in the features chart.) The driver software packages provide a high level interface to the RTI-800 Series analog and digital boards. Complex analog, digital, and counter/timer I/O operations are simplified with keywords such as SCAN, AOT, FINSTART. In order to use the driver software, experience with a programming language such as BASIC or VISUAL BASIC for Windows and familiarity with the application is required.
Each SW800 Series driver software package consists of all language
libraries and a board library for the specific hardware
supported. The language libraries include a language binding
that handles the different parameter passing conventions used
by the languages, as well as calls to the hardware libraries.
Board libraries contain the low level subroutines that perform
the I/O routines. Common language-specific packages within
the SW800 Series can be merged to run in one system. For example,
if a user wants to operate an RTI-815 and
RTI-827 board
in the same system and wants to develop an application in
Microsoft C ++ , the SW-800 and SW-827
packages can be combined
using the LINK facility.
An error-processing system checks for argument errors in
every setup and I/O subroutine. Attempts to operate in
illegal modes are trapped, and error codes are reported.
Run-time errors such as "Overrun error detected" are also
reported.
Table I lists the I/O routines in the SW800 Series of MS-DOS
and Windows Driver Software packages. The target system
for the SW800 Series of Driver Software is an IBM PC/AT
or 100% compatible system with PC-DOS, MS-DOS (Version
3.3 or higher), or Windows 3.1, and one floppy disk
drive and one hard disk drive.
Table II lists application software packages, available from
third party vendors, which require little or no programming
on the part of the user prior to configuring and running an
application. Applications range from simple data collection
and analysis to real-time control and high speed streaming
of data to disk.
