5.4.2.3 Camera link output (1 tap output)
If 1 tap output is selected, monochrome, Bayer (8-bits, 10-bits or 12-bits) or RGB (8-bits
only) output can be output through Camera Link interface without dividing the image.
For 1 tap output, the frame rate is 32.2fps.

5.4.2 Partial scan readout (AOI) (Commands: STL, ETL)
The AOI works like partial scanning. By using the AOI function, a faster frame rate can be
achieved. The start line of the image (Offset Y) and the image height (Height) can be set as
desired. However, the start pixel and/or end pixel of each line cannot be changed. In the
AM-201CL and AB-201CL RGB output, The Offset Y and Height can be set in 1 line
increments. For the AB-201CL Bayer mode, output can be set in 2-line steps.
STL: Offset Y (Read out start line)
ETL: Height (Readout line numbers)

Note for AOI setting
In the AM-201CL and AB-201CL, the frame rate setting has priority. If AOI is used, the frame
rate setting should use fewer lines that that of AOI height.
For AOI setting, if the upper TAP and lower TAP have the same duration, the fastest frame
rate can be achieved. Thus, if the AOI is centered vertically within the image, the frame
rate is maximized. Examples of the settings are shown in sections 5.4.2.4 and 5.4.2.5.
