sub-buses. The NI PXI-1409 works in any standard CompactPCI chassis
adhering to the
PICMG 2.0 R2.1 CompactPCI
core specification using the
64-bit definition for J2.
PXI-specific features are implemented on the J2 connector of the
CompactPCI bus. Table 1-1 lists the J2 pins the NI PXI-1409 uses. The
NI PXI-1409 is compatible with any CompactPCI chassis with a sub-bus
that does not drive these lines.
Caution
Even if the sub-bus is capable of driving these lines, the NI PXI-1409 is still
compatible as long as those pins on the sub-bus are disabled by default and are never
enabled. Damage may result if these lines are driven by the sub-bus.
Software Overview
Programming the NI 1409 requires the NI-IMAQ driver software for
controlling the hardware. National Instruments also offers the following
application software packages for analyzing and processing your acquired
images:
•
Vision Builder for Automated Inspection (AI)
—Allows you to
configure solutions for common inspection tasks.
•
Vision Development Module
—Provides customized control over
hardware and algorithms.
The following sections provide an overview of the driver software and
application software. For detailed information about individual software
packages, refer to the documentation specific to the package.
NI-IMAQ Driver Software
The NI 1409 ships with NI Vision Acquisition Software, which includes
the NI-IMAQ driver software. NI-IMAQ has an extensive library of
functions—such as routines for video configuration, continuous and
single-shot image acquisition, memory buffer allocation, trigger control,
