5.4.1.2 Camera link output (2 tap output)
The AM-201CL and AB-201CL have a 4-tap readout from the CCD. The 4-tap output is
combined horizontally to output 2 taps through the Camera Link interface.
The command SDT (Sensor Digitization Taps) can select “0” for 2 taps and “1” for 1 tap.
If 2 taps is selected, the monochrome or Bayer output (8-bits, 10-bits or 12-bits) can be
output through the Camera link interface, divided into top and bottom halves.
In this case, the frame rate is 64.2fps.
