the serial read didnot complete within the specified timeout period

[xiaoran94]

I have been using a Cobra-SRC and a frame grabber PCIe-1433 of NI for a while. I use LABVIEW to make Cobra-SRC work and used MATLAB to read data from PCIe-1433. Before they all ran well but now, when grabbing, it showed a dialog in LABVIEW:"IMAQ error: the serial read didnot complete within the specified timeout period". And an error occurs in MATLAB: "ni: cannot detect recognizable video source". I'm so confused that I did not change anything in MATLAB and LABVIEW. Could someone answer me this question???? Thank you in advance.

Sounds like a Cable is loose and/or the Camera (or its hardware) cannot be detected by the PC.

Hi xiaoran94,

Does the camera show up in NI MAX and Windows Device Manager? Can you see anything using the Camera Link Logger for the NI-1433? (See downloads on the right of the page.) Could you try unplugging the camera and plugging it back in again?

Let us know how you get on.

Best regards,

Leah

Hi 

The reason why NI Measurement Automation Explorer (NI-MAX) cannot detect video source has been found. An error occurs in NI-MAX that makes camera file invalid. I reinstalled the NI-MAX and LabVIEW. In addition, I downloaded the camera file again. Now, NI-MAX can detect the spectrometer again. But I still don't know why camera file became invalid suddenly. I did not update anything of NI-MAX or Windows system.

But anyway, thank you for your reply!

Regards
