7.8. Pre-dump mode (so-called RCT)
Until the trigger is input, the camera operates continuously and the video signal for the
auto-iris lens is output. At this moment, the video signal, FVAL and LVAL are output but
DVAL is not output. When the trigger is input, the fast dump is activated to read out
the electronic charge very quickly, after which the accumulation and the readout are
performed. This fast dump period is 5.275ms (in the case of Binning OFF). When the
accumulated signal against the trigger is read out, FVAL, LVAL and DVAL are output too.
The frame rate for full pixels readout is;
2 tap output: 68fps + Fast dump Exposure time
1 tap output: 34.2fps + Fast dump Exposure time
Primary settings to use this mode
Sensor Digitization Taps: SDT= 0 (Two taps) SDT=1 (One tap)
Acquisition control
Acquisition frame rate:
AR= 1

Overlap : Non overlap only
Note
:
The AM-200CL and AB-200CL gives priority to the frame rate over the exposure
time. If the exposure time is set at longer than 16.64ms (1 frame period), the frame
rate must be increased so that it is longer than the exposure time.
