Difference from PCI-1424 (comparison within the same series)

PCI-1422: 1/2 channel, 40 MHz, 80 MB/s, 16 MB cache, LVDS/RS-422

PCI-1424: 2/4 channels, 50 MHz, 200 MB/s, 16–80 MB cache, LVDS/RS-422

Alternative models (direct upgrade)

PCIe-1429: PCIe, 4 channels 10-bit black & white / color, compatible with traditional IMAQ

PCIe-1433: Camera Link digital, 4 channels high-speed 10-bit grayscale, preferred for new projects

PCIe-1427: PCIe, 1/4 channel LVDS/RS-422, direct replacement for PCI-142
