NI PCI-1422 and NI PXI-1422 16-bit, Parallel Digital image acquisition boards


The National Instruments PCI-1422 Series boards are designed to acquire images from a wide range of digital cameras. The NI PCI-1422 Series performs high-speed, large-image, high-resolution digital image capture, and can capture up to 16 bits of data at a clock speed of 40 MHz for a total acquisition rate of 80 Mbytes/s. Onboard memory (16 MB) gives you the flexibility to buffer images on the board for large-image capture and sustained real-time throughput. There are two versions of the board -- one compatible with RS-422 signals and one compatible with LVDS camera signals.

  • 8, 10, 12, and 16-bit (grayscale or color) digital image     acquisition boards
  • Easy-to-use configuration utility
  • 40 MHz pixel clock rate with up to 80 Mbytes/s acquisition
        Serial interface and 4 TTL or RS-422 control lines for     integrated camera control
  • RS-422 or LVDS camera compatibility
  • 4 programmable digital I/O lines for triggering and control
  • Specifications
    Typical at 25° C, unless otherwise stated.
