About Your 1408 Device

© National Instruments Corporation
This chapter describes the PCI-1408 and PXI-1408 devices and describes
your software programming choices.
The PCI-1408 and PXI-1408 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 nonstandard
cameras from any of four input sources. The boards feature an 8-bit flash
analog-to-digital converter (ADC) that converts video signals to digital
formats. The 1408 devices acquire frames in real time and transfer them
directly to system memory.
The 1408 device is simple to configure so that you can easily install the
board and begin your image acquisition. The 1408 device ships with
NI-IMAQ, the National Instruments complete image acquisition driver
software you can use to directly control your 1408 device. Using NI-IMAQ,
you can quickly and easily start your application without having to program
the board at the register level.
Featuring low cost and high accuracy, the 1408 device is ideal for
both industrial and scientific environments. As a standalone board, the
1408 device supports four video sources and four external I/O lines that
you can use as triggers or digital I/O lines. If you require more advanced
triggering or additional I/O lines (either digital or analog), you can use the
1408 device and NI-IMAQ with the National Instruments data acquisition
(DAQ) product line.
A common problem with image acquisition boards is that you cannot easily
synchronize several functions to a common trigger or timing event. The
1408 device 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
