Introduction
This chapter describes the PXI-1409 and PCI-1409 devices and your
software programming choices.
About the IMAQ 1409 Device
The PXI-1409 and PCI-1409 devices are high-accuracy, monochrome
image acquisition (IMAQ) devices for PXI, PCI, or CompactPCI chassis
that support RS-170, CCIR, NTSC, and PAL video standards, as well
as some nonstandard cameras from any of four input sources. The
IMAQ 1409 features a 10-bit analog-to-digital converter (ADC) that
converts video signals to digital formats. The IMAQ 1409 device acquires
images in real time and stores them in onboard frame memory or transfers
them directly to system memory.
The IMAQ 1409 is easy to install and configure. It ships with NI-IMAQ,
the National Instruments complete image acquisition driver software you
can use to directly control the IMAQ 1409 device and other National
Instruments IMAQ devices. With NI-IMAQ, you can quickly and easily
start your applications without having to program the device at the register
level.
As a standalone device, the IMAQ 1409 device supports four
general-purpose control lines that are configurable to generate precise
timing signals for controlling camera acquisition. The IMAQ 1409 device
also supports four video sources and four external I/O lines to use as
triggers or digital I/O lines.
Easily synchronizing several functions to a common trigger or timing event
is a common challenge with image acquisition devices. The IMAQ 1409
uses its Real-Time System Integration (RTSI) bus to solve this problem.
The RTSI bus uses the National Instruments RTSI bus interface and ribbon
cable to route additional timing and trigger signals between the IMAQ 1409
device and up to four National Instruments DAQ, Motion Control, or other
IMAQ devices. The RTSI bus can even synchronize multiple IMAQ
hardware captures.

Refer to Figure 1-1 for the location of the IMAQ 1409 W1 jumper and the
connectors discussed in this manual.
Figure 1-1. PCI-1409 Parts Locator Diagram
Using PXI with CompactPCI
Using PXI-compatible products with standard CompactPCI products is an
important feature provided by the PXI Specification, Revision 1.0. If you
use a PXI-compatible plug-in device in a standard CompactPCI chassis,
you cannot use PXI-specific functions, but you can still use the basic
plug-in device functions. For example, the RTSI bus on the PXI-1409
device is available in a PXI chassis, but not in a CompactPCI chassis.
The CompactPCI specification enables vendors to develop sub-buses that
coexist with the basic PCI interface on the CompactPCI bus. Compatible
operation is not guaranteed between CompactPCI devices with different

sub-buses or between CompactPCI devices with sub-buses and PXI.
The standard implementation for CompactPCI does not include these
sub-buses. The PXI-1409 device 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 PXI-1409 device uses.
The PXI device 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 PXI device 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 IMAQ 1409 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.
NI-IMAQ Driver Software
The NI-IMAQ driver software ships with the IMAQ 1409 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), memory
buffer allocation, trigger 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 NationalInstruments ApplicationSoftware sectionofthis chapter.
NI-IMAQ is also the interface path between LabVIEW,
LabWindows™/CVI™, or a text-based programming environment and 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.
NI-IMAQ handles many of the complex issues between the computer and
the IMAQ device, such as programming interrupts and camera control.
National Instruments Application Software

Hardware Overview
This chapter describes the features of the IMAQ 1409 device and includes
information about acquisition modes, analog front-end considerations, and
clamping.
Functional Overview
The IMAQ 1409 features a flexible, high-speed data path optimized for the
acquisition and formatting of video data from analog cameras. The
IMAQ 1409 device can acquire from RS-170/NTSC, CCIR/PAL, VGA,
and progressive scan cameras, as well as from non-standard cameras such
as line scan cameras. The IMAQ 1409 device digitizes analog video signals
to 8 or 10 bits of resolution at sampling frequencies up to 40 MHz.
The IMAQ 1409 has a factory-calibrated gain circuit to improve
measurement accuracy and board-to-board consistency. It uses a PCI
interface for high-speed data transfer, 16 MB of SDRAM for data
buffering, and region-of-interest control circuitry for optimizing the data
transfer. The 16 MB of SDRAM also allows you to acquire entire images
into onboard memory when necessary. The IMAQ 1409 includes
four external triggers, four camera control signals, seven RTSI bus triggers,
and six video synchronization signals.
