for the default setting by clicking 50 Hz or 60 Hz .
d. For Memory Size , select the amount of memory (in MB) that
you want to allocate in your system to hold the acquired
frames. A 60 Hz, 640-by-480 image requires 308 KB per
frame; a 50 Hz, 768-by-576 image requires 443 KB per frame.
The upper limit depends on your system’s resources.
The
recommended minimum is 1 MB.
11. To configure the board for line-scan (one-dimensional)

enable the board for both 2 Dimensional Mode and Line Scan
mode at the same time. However, to maximize system memory,
enable only one mode at a time.
