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. DATEL’s 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 DATEL’s 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.
