I'm glad to hear that these errors are all related. Normally, during acquistion, the camera cable is not disconnected. I'd disconnected the camera cable to simulate any breaks along the camera to PC path, as it was the easiest point to access. We do have an otpion that switches between 2 cameras. The grab is off one camera. The operator can switch to a second camera for a different view, which causes some degradation of the image during the switch but does not discontinue the video feed. We think we can rule out the effects of the switch as the cause of the timeouts. The other thread that muks found may apply to us since we did upgrade the motion and vision drivers at the time these errors began. I'll look into that some more.
Thanks much.
