Using two scan progressive cameras with 1409?

[Francesc]

I need to use two scan progressive cameras with the 1409. The two cameras are two sony XC-55 (30Hz). I have configured one as a Master and the other as Slave. I have connected the HD and VD of each camera between them.

I acquire a sequence of frames (normally I take five)of each camera every time that a triggeg ocurrs. Time to time I get some frames in the slave camera that the first line of the frame is not at the top. Not always in the same position. Sometimes I don't received the last or the two last frames.

In the past I used the same configuration with the 1408 and 1408 always tooks correctly all the frames from the two cameras.

Please, help me?

Thanks, in advance

It seems like there would be two possibilities. Either the camera is outputting data like that or the board isn't reading it correctly. Since it worked fine with the 1408 it should work the same with the 1409. I would be interested in knowing if you can switch between a 1408 and a 1409 see the behavior in one or the other. That would narrow the issue down I think.

I think the board isn't reading correctly the frames. I have some systems installed with the 1408 and they work correctly. I will send you some frames which show the problem and the vi that I use to capture them. The .icd file that I use with the 1409 is 30 Hz progressive and the .icd file that I use with the 1408 is scan area.

It is possible that I can solve the problem changing the parameters of the icd file? Do you have information about them?
