PC-414LV GENERAL DESCRIPTION
National Instruments’ LabVIEW transforms the PC-414 family
of high speed analog input boards into easy-to-use virtual
instruments (VI’s) that acquire, analyze, display, and store
analog signals in real time. Low level software development is
replaced by an intuitive visual programming system that
harnesses all the power of Microsoft Windows - graphic user
interface (GUI), access to more host memory (16
megabytes), multi-tasking, and inter-process communications
using DDE. Applications include highly concurrent system
testing, process monitoring and control, telemetry, radar,
sonar, acoustics, DSP front end quantizer, education, and
research.
The PC-414 LabVIEW package from DATEL consists of a set
of inexpensive VI’s for low level control of the board. These
integrate into the LabVIEW package which the user must
purchase from National Instruments. Once installed, these
VI’s appear as icons on the LabVIEW menues. DATELs VI’s
are offered in two versions. Model PC-414LV is the
executable binary-only configuration which can be fully
integrated into the user-written block diagram. Model
PC-414LVS is the full source to model PC-414LV and also
includes all binaries. The source code should be considered
by a programmer who wishes to extend or modify the existing
VI’s or just wants to more fully understand their operation.
LabVIEW’s feature-rich program development system
combined with DATELs library of VI functions for the PC-414
provide the essential building blocks to create any conceivable
LabVIEW applications.
Graphical programming works like a flowchart - when the
flowchart is accurate and complete, the program is done.
PC-414LV off-loads as much programming as possible into
the LabVIEW environment so the user has maximum control.
It creates a library of fast, simple, highly modular VI functions
for the PC-414 that do not sacrifice board performance. The
user builds VI’s to configure the data acquisition hardware,
process the data, and ultimately display and store that data
without writing programs. Similar VI’s can be created to
update the analog output and to read and write the digital I/O
port.
