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 industrialcommercial 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 labelled 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. The curious reader can consult the FCC web site http://www.fcc.gov for more information.

FCC/DOC Warnings

This chapter describes the PCI-1424 and describes your software programming choices.

About the PCI-1424
The PCI-1424 is a highly flexible, monochrome and color, PCI-based IMAQ board that supports a diverse range of digital cameras from many camera companies. The PCI-1424 acquires digital images in real time and can store these images in onboard frame memory, or transfer these images directly to system memory. The board can capture up to 32 bits of data at a time at clock speeds up to 50 MHz.1 The PCI-1424 is simple to configure so that you can easily install the board and begin acquiring images. The PCI-1424 ships with NI-IMAQ, the National Instruments complete IMAQ driver software you can use to directly control the PCI-1424 and other National Instruments IMAQ hardware products. Using NI-IMAQ, you can quickly and easily start your applications without having to program the board at the register level. Featuring a high-speed data flow path, the PCI-1424 is ideal for both industrial and scientific environments. As a standalone board, the PCI-1424 supports up to 32 bits of differential or TTL level video data, four general purpose control lines that can be configured to generate precise timing signals to control digital camera acquisition, and four external input/output (I/O) lines that you can use as triggers or as high-speed digital I/O lines. If you require more advanced triggering or digital I/O lines (either digital or analog), you can use the PCI-1424 and NI-IMAQ with the National Instruments data acquisition (DAQ) product line.

Introduction

A common problem with image acquisition boards is that you cannot easily synchronize several functions to a common trigger or timing event. The PCI-1424 uses its Real-Time System Integration (RTSI) bus to solve this problem. The RTSI bus consists of the National Instruments RTSI bus interface and ribbon cable to route additional timing and trigger signals between the PCI-1424 and up to four National Instruments DAQ or IMAQ boards in your computer. The RTSI bus can even synchronize multiple IMAQ hardware captures. Detailed specifications of the PCI-1424 are in Appendix A, Specifications.

Software Programming Choices
Using NI-IMAQ, the National Instruments image acquisition driver software, you can program your IMAQ board 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. NI-IMAQ works with LabVIEW, BridgeVIEW, LabWindows/CVI, as well as 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.

Figure 1-2. NI-IMAQ Functions

The NI-IMAQ driver software performs all functions required for acquiring and saving images. The NI-IMAQ software does not perform any image analysis. For image analysis functionality, refer to the National Instruments IMAQ Vision section in this chapter. NI-IMAQ has both high-level and low-level functions for maximum flexibility and performance. Examples of high-level functions include the functions to acquire images in single-shot or continuous mode. An example of a low-level function is configuring an image sequence 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, BridgeVIEW, LabWindows/CVI, or a conventional programming environment and your IMAQ device. The NI-IMAQ software kit includes a series of libraries for G, LabWindows/CVI, and ComponentWorks (ActiveX) that are functionally equivalent to the NI-IMAQ software.

National Instruments IMAQ Vision
IMAQ Vision is an image acquisition, processing, and analysis library of more than 200 functions for grayscale, color, and binary image display, image processing, pattern matching, shape matching, blob analysis, gauging, and measurement. You can use IMAQ Vision functions directly or in combination for unique image processing. With IMAQ Vision you can acquire, display, manipulate, and store images as well as perform image analysis, processing, and
