NI 1483 Camera Link adapter module

National Instruments is offering a vision module for the PXI platform that provides a high-performance parallel processing architecture for hardware-defined timing, control and image pre-processing.

The NI 1483 Camera Link adapter module, in combination with an NI FlexRIO FPGA board, offers a solution for embedding vision and control algorithms directly on FPGAs which are used to process and analyze an image in real time with little to no CPU intervention.

The FPGAs can be used to perform operations by pixel, line and region of interest. They can implement many image processing algorithms that are inherently parallel, including fast Fourier transforms, thresholding and filtering.

The NI 1483 is suitable for optical coherence tomography and high-speed control systems for applications such as laser alignment and sorting.

The module is also suitable for acquisition from Camera Link devices with custom tap configurations and high-resolution sensors measuring more than 10MPixel requiring hardware-based pre-processing.

The module supports base-, medium- and full-configuration Camera Link devices as well as 80bit 10-tap configurations, all up to 85MHz. This design enables customization of the image acquisition when using custom image sensors. The 85MHz measurement supports the Camera Link standardized specification to its fullest, creating a good fit for those working on applications with high frame rates.

The module also integrates several I/O options including four TTL I/O lines, two opto-isolated inputs and one quadrature encoder input in addition to the many modular I/O and industrial communication options available for the PXI platform.

The NI FlexRIO hardware can be customized using the LabVIEW FPGA Module without knowledge of low-level hardware description languages or board-level design.
