An interrupt is generated whenever an even field, an odd field, or a
noninterlaced frame is acquired; the PCI bus assigns the interrupt to
the DT3152-LS board automatically when it is installed.
The speed of the PCI bus allows the DT3152-LS to transfer an
unlimited number of consecutive frames across the bus in real time.
You can acquire and store consecutive images, up to the capacity of
available system memory.
Acting as a PCI bus master, the DT3152-LS board sends pixel data
over the PCI bus directly using burst transfer rates up to 30 frames/s
for 60 Hz image formats and 25 frames/s for 50 Hz image formats.
