CCIR camera in PXI1409 gives black image with synching noise

[robd]

After installing a PXI1409 card we added a digital camera. This worked fine. A couple of days later we came back and found that the only image we get is black with white lines on it. The lines appear to be some sort of synching noise, and are only visible with the white reference level set very low.

We have tried reinstalling the card and the IMAQ software but to no avail. No changes in settings in MAX give a different image.

Any ideas?

Hello,

1409 is an analog frame grabber.
- Does your camera also generate an analog CCIR signal that you connected to 1409?
- Did you configure the corresponding channel to acquire a CCIR signal in MAX?
- Did you try the same camera with a different frame grabber or the same frame grabber with a different camera?

Apologies, the cameras are analogue. We've tried two different CCIR BW cameras, both of which work fine on a SCION LG3 framegrabber, and plugged directly into a BW monitor.

We have configured MAX to take a CCIR signal from the BNC connector on the front panel, ie channel 0.

Many thanks for your quick response,
