Compliance
FCC/Canada Radio Frequency Interference Compliance*
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC
places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)
or Class B (for use in residential or commercial locations). Depending on where it is operated, this product could be subject to
restrictions in the FCC rules. (In Canada, the Department of Communications (DOC), of Industry Canada, regulates wireless
interference in much the same way.)
Digital electronics emit weak signals during normal operation that can affect radio, television, or other wireless products. By
examining the product you purchased, you can determine the FCC Class and therefore which of the two FCC/DOC Warnings
apply in the following sections. (Some products may not be labeled at all for FCC; if so, the reader should then assume these are
Class A devices.)
FCC Class A products only display a simple warning statement of one paragraph in length regarding interference and undesired
operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations where FCC Class A
products can be operated.
FCC Class B products display either a FCC ID code, starting with the letters EXN,
or the FCC Class B compliance mark that appears as shown here on the right.
Consult the FCC web site http://www.fcc.gov for more information.

Introduction
This chapter describes the IMAQ PCI/PXI-1407 devices and your software
programming choices.
About Your 1407 Device
The PCI-1407 and PXI-1407 are high-accuracy, monochrome IMAQ
devices for PCI, PXI, or CompactPCI chassis that support RS-170 and
CCIR video standards. The PCI/PXI-1407 acquires frames in real time and
transfers them directly to system memory. Revisions E and later of the
PCI-1407 and revisions C and later of the PXI-1407 support progressive
scan formats 25, 30, 50, and 60 frames per second and feature gain
calibration, high-impedance mode, and an 8-bit flash analog-to-digital
converter (ADC) that converts video signals into digital form.
Because the 1407 device is simple to configure, you can easily install the
device and begin your image acquisition. The PCI/PXI-1407 ships with
NI-IMAQ, the National Instruments complete image acquisition driver
software you use to directly control your device. Using NI-IMAQ, you can
quickly and easily start an application without having to program the device
at the register level.
Featuring low cost and high accuracy, the PCI/PXI-1407 is ideal for
both industrial and scientific environments. As a stand-alone device, the
PCI/PXI-1407 supports one video source and an external I/O line that
you can use as a trigger or digital I/O line. If you require more advanced
triggering or additional I/O lines (either digital or analog), you can use
the PCI/PXI-1407 and NI-IMAQ with the National Instruments data
acquisition (DAQ) product line.
See Appendix A, Specifications,for detailed PCI/PXI-1407 specifications.

Chapter 1 Introduction
IMAQ PCI/PXI-1407 User Manual 1-2 ni.com
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 will be unable to use PXI-specific functions, but you can still use the
basic plug-in device functions.
The CompactPCI specification permits 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. Your PXI-1407 device will work in any standard CompactPCI
chassis adhering to the PICMG 2.0 R2.1 CompactPCI core specification.
Software Programming Choices
Using NI-IMAQ, the National Instruments image acquisition driver
software, you can program your IMAQ device to acquire and save images.
You can use NI-IMAQ with other National Instruments software for a
complete image acquisition and analysis solution, as shown in Figure 1-1.
NI-IMAQ works with LabVIEW and LabWindows/CVI, as well as with
conventional programming languages. National Instruments’
IMAQ Vision adds powerful image processing and analysis to these
programming environments. You can also use IMAQ Vision Builder to
quickly and easily prototype your IMAQ image analysis applications.

NI-IMAQ Driver Software
The NI-IMAQ driver software is included with your IMAQ device.
NI-IMAQ has an extensive library of functions that you can call from your
application programming environment. These functions include routines
for video configuration, image acquisition (continuous and single-shot),
memory buffer allocation, trigger control, and board configuration, as
shown in Figure 1-2.
Figure 1-2. NI-IMAQ Functions
The NI-IMAQ driver software performs all of the functions required for
acquiring and saving images. However, the NI-IMAQ software does not
perform image analysis. For image analysis functionality, refer to the
IMAQ Vision section in this chapter.
For maximum flexibility and performance, NI-IMAQ has both high-level
and low-level functions. The functions to acquire images in single-shot or
continuous mode are examples of high-level functions. Configuring an
imaging sequence is an example of a low-level function, since it requires
advanced understanding of your IMAQ device and image acquisition.
NI-IMAQ internally resolves many of the complex issues between the
computer and your IMAQ device, such as programming interrupts and
DMA controllers.
NI-IMAQ is also the interface path between LabVIEW, LabWindows/CVI,
or a conventional programming environment and the IMAQ device. The
NI-IMAQ software kit includes a series of libraries for image acquisition
for LabVIEW and Measurement Studio, which contains libraries for
LabWindows/CVI, Visual C++, and Visual Basic. These libraries are
functionally equivalent to the NI-IMAQ software.
