Frame Grabber support for display data without HSYNC

[aamaro]

I am using NI 1424 frame grabber and I am trying to interface it with display  data with only  pixel data, pixel clock and VSYNC signals. Is there anyway that I could set this with the Frame grabber card without the HSYNC signal??

Hello aamaro,

I have good news and bad news for you.

The bad news is that the NI 1424 card requires an HSYNC input signal.  There is no way that you can configure the card to function properly without an HSYNC input signal.   

The good news is that you can generate an HSYNC signal externally and then pass the externally generated HSYNC signal to the NI 1424.  You may want to consider an NI R Series DAQ card for this job so that you can bring FPGA technology to bear on the task.  You can find more information on NI's R Series Intelligent DAQ devices here. 

Best Regards,

Depending on the exact nature of your camera's signals, you should be able to create a custom camera file.  Create it as a linescan camera, and wire your VSYNC into the HSYNC input.  After you acquire the image, you'll need to reshape it, since it will come in as a single line.  A bit ugly, but it should work.

Out of curosity, what kind of camera is this?
