The National Instruments PCIe-1427 Camera Link Image Acquisition Device, identified by part number 779706-01, is engineered for high-performance real-time digital image acquisition. This module facilitates the direct transfer of acquired images to system memory, optimizing processing efficiency for both scientific and industrial applications. The PCIe-1427 supports 24 parallel data bits, enabling rapid transmission of high-resolution pixel data from the camera to the device.

Equipped with four essential enable signals—Frame Valid (FVAL), Line Valid (LVAL), Data Valid (DVAL), and a spare signal for future use—the module efficiently manages frame synchronization and data integrity during image capture. Supporting baud rates up to 115200 bits per second, the PCIe-1427 offers a versatile serial communication interface, improving the flexibility and responsiveness of image acquisition operations.

In addition, the device generates precise real-time control signals essential for synchronizing various components in imaging systems, such as managing camera exposure times and frame rates. The integration of Scatter-gather Direct Memory Access (DMA) Controllers enhances data transfer capabilities, allowing efficient memory utilization by enabling non-contiguous memory blocks. This feature is particularly beneficial for handling large image files or continuous streams of data, ensuring minimal CPU load during operations.

The PCIe-1427’s robust design includes connectors for MDR 26-Pin and 15-Pin D-SUB, and it operates effectively within a temperature range of 0 to 55 °C, with a storage temperature range of -20 to 70 °C, making it suitable for diverse environmental conditions.
