The National Instruments 777959-01 Image Acquisition Module, known as the PCI-1422, is a versatile solution designed for integration within PCI, PXI, and CompactPCI chassis. This module supports a broad spectrum of digital cameras from various manufacturers, facilitating real-time image acquisition with the ability to capture data at 16 bits and clock speeds of up to 40 MHz. The module allows users to store images in its onboard frame memory or transfer them directly to system memory, ensuring efficient data handling.

Factory calibrated for ease of use, the 777959-01 simplifies the installation process and enables immediate photo capture. It is bundled with NI-IMAQ, National Instruments' comprehensive image acquisition driver software, which allows for intuitive control over the module and other IMAQ components without the necessity for low-level programming. This streamlined approach reduces setup time significantly, making it well-suited for both industrial and scientific applications.

The module features four general-purpose control lines that can be configured to generate precise timing signals for digital camera operations. Furthermore, it includes four external input/output connections, which can function as high-speed digital I/O lines or trigger signals. The 777959-01 can be integrated with the National Instruments data acquisition (DAQ) product line to enhance triggering capabilities and expand digital I/O options.

Addressing common synchronization challenges associated with image acquisition, the 777959-01 incorporates Real-Time System Integration (RTSI) bus support, enabling coordinated captures across multiple IMAQ hardware units. By utilizing a ribbon cable and the RTSI bus interface, users can seamlessly transmit timing and trigger signals among the 777959-01 and up to four additional National Instruments DAQ or IMAQ boards within the system.

Additionally, the module includes the NI-IMAQ VI Library for G, which comprises a collection of virtual instruments specially designed to be compatible with BridgeVIEW and LabVIEW, thereby enhancing its functions. This library provides interactive graphics, advanced user interfaces, and a robust graphical programming environment, further expanding the usability of the 777959-01 Image Acquisition Module.
