© National Instruments Corporation 1-1 IMAQ PCI/PXI-1409 User Manual1IntroductionThis chapter describes the PCI-1409 and PXI-1409 devices and describesyour software programming choices.About Your 1409 DeviceThe PCI-1409 and PXI-1409 devices are high-accuracy, monochrome,IMAQ boards for PCI, PXI, or CompactPCI chassis that support RS-170,CCIR, NTSC, and PAL video standards as well as some nonstandardcameras from any of four input sources. The boards feature a 10-bitanalog-to-digital converter (ADC) that converts video signals to digitalformats. The PCI-1409 acquires images in real time and can store theseimages in onboard frame memory or transfer these images directly tosystem memory.The 1409 device is simple to configure so that you can easily install theboard and begin your image acquisition. The 1409 device ships withNI-IMAQ, the National Instruments complete image acquisition driversoftware you can use to directly control your 1409 device. Using NI-IMAQ,you can quickly and easily start your application without having to programthe board at the register level.Featuring low cost and high accuracy, the 1409 device is ideal forboth industrial and scientific environments. As a standalone board, the1409 device supports four general purpose control lines that you canconfigure to generate precise timing signals for controlling cameraacquisition. The 1409 device also supports four video sources and fourexternal I/O lines that you can use as triggers or digital I/O lines. If yourequire more advanced triggering or additional I/O lines (either digital oranalog), you can use the 1409 device and NI-IMAQ with the NationalInstruments data acquisition (DAQ) product line.A common problem with many image acquisition boards is that you cannoteasily synchronize several functions to a common trigger or timing event.The 1409 device uses its Real-Time System Integration (RTSI) bus to solvethis problem. The RTSI bus consists of the National Instruments RTSI bus
