between the PCI-1424 and up to four National Instruments DAQ or IMAQ
devices in your computer. The RTSI bus can even synchronize multiple
IMAQ hardware captures.
Detailed specifications of the PCI-1424 are in Appendix A, Specifications.
Programming the PCI-1424 device requires the NI-IMAQ driver software
for controlling the hardware and one of the following application software
packages for image processing:
•
Vision Builder for Automated Inspection (AI)—for configuring
solutions to common inspection tasks
•
National Instruments Vision Development Module—for more
customized control over hardware and algorithms
The following sections provide an overview of the driver software and the
application software. For detailed information about individual software
packages, refer to the documentation specific to the package.
The NI-IMAQ driver software ships with the PCI-1424 device. NI-IMAQ
has an extensive library of functions you can call from your application
programming environment, such as routines for video configuration, image
acquisition (continuous and single-shot),
control, and device configuration.
NI-IMAQ performs all functions required for acquiring and saving images
but does not perform image analysis. For image analysis functionality, refer
to the

IMAQ device. The NI-IMAQ software kit includes a series of libraries for
image acquisition for LabVIEW, LabWindows/CVI, and Measurement
Studio, which contains libraries for Visual Basic.
For maximum flexibility and performance, NI-IMAQ features both
high-level and low-level functions. Examples of high-level functions
include the sequences to acquire images in multi-buffer, single-shot, or
continuous mode. An example of a low-level function is configuring an
image sequence, since it requires advanced understanding of the IMAQ
device and image acquisition.
