Issue Details

I have two Camera Link cameras that I need to acquire images from simultaneously. Which card(s) should I use?

Solution

You can do either of the following:
  • You can use two other Frame Grabber Devices that have RTSI lines accessible and use the HL Grab with Two Boards.vi located in the NI Example Finder. (Open NI Example Finder Click Hardware Input Output >> Vision Acquisition >> NI-IMAQ >> Signal Input and Output. This is where you will find the HL Grab with Two Boards.vi)
  • Previously, NI sold the PCIe-1430 Frame Grabber Device. This card is now in the Maintenance lifecycle stage and can no longer be purchased. However, if you already own a PCIe-1430 then you can use the card to acquire from two Camera Link cameras connected in Base configuration mode only (Medium, full and Extended-Full configurations are not supported by the PCIe-1430). Both cameras are using the same triggering hardware meaning you can simultaneously acquire images using an external trigger line.
