1424 Cannot Detect Recognizable Video Source

[rrojas1979]

All,

I am using an NI PCI1424 frame grabber with a DRS 3G640 LW camera. My IMAQ driver version is 3.7.1. I am sure that my camera file is created correctly as I have gone over and over the timing diagram provided with the camera documentation.

When I set the frame grabber to use my camera file in MAX, and I select either "snap" or "grab," I get the error 0xBFF6001F: Cannot Detect Recognizable Video Source.

A colleague has used the frame grabber and cable recently with another camera and it has worked fine. Checking the 3G640 LW camera signals yields positive results on the pixel clock, frame sync, and line sync signals.

Any clues as to what could be causing this message?

Thanks.

Make doubly sure that the cable is  proper.Try changing the  cable if u have a spare.


If the problem is not fixed  try changing the PCI slot(Likely)

Thanks for the suggestions. Now, if MAX is telling me that the 1424 is using RS-422 signal levels, this pretty much means we are using the RS-422 version of the 1424, correct? If this is the case, why is the 1424 capable of acquiring images from a different LVDS camera that I tested earlier today?

We tested the pixel clock, line valid, and frame valid signals coming off the camera and they are all correct LVDS signals. But if MAX is telling me my board is a RS-422 board, would this cause an inability for the board to detect the pixel clock?
