set_framegrabber_param

grab_timeout

timeout (milliseconds, default 5000) for aborting a pending grab. If -1 is specified, the timeout is set to INFINITE.

set_framegrabber_param(AcqHandle, 'grab_timeout', 10000)

grab_image_start

MaxDelay: This parameter is obsolete and has no effect.

grab_image_start (AcqHandle, -1)

grab_data_async

The grab of the next image is finished by calling grab_data_async or grab_image_async. If more than MaxDelay ms have passed since the asynchronous grab was started, the asynchronously grabbed image is considered as too old and a new image is grabbed, if necessary. If a negative value is assigned to MaxDelay, this control mechanism is deactivated.
