Introduction
About the IMAQ PCI-1424

Early versions of the PCI-1424 may not support acquisitions at 50 MHz. For the exact maximum acquisition clock rate of your
PCI-1424, refer to the Maximum Clock Rate indicator in Measurement & Automation Explorer.

This chapter describes the IMAQ PCI-1424 device and describes your
software programming choices.
The PCI-1424 is a highly flexible, monochrome and color, PCI-based
image acquisition (IMAQ) device 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 device can capture
up to 32 bits of data at a time at clock speeds up to 50 MHz.
The PCI-1424 is simple to configure so that you can easily install the
device 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 device 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 device, 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.
A common problem with image acquisition devices is that you cannot
easily synchronize several functions to a common
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
