10.5.4 Reset Continuous Trigger (RCT) mode
The RCT mode operates like EPS (edge preselect) mode with smearless function. An external
trigger pulse will immediately stop the video readout, reset and restart the exposure, then
operate as normal mode until the next trigger. After the trigger pulse is input, a fast dump
readout is performed. In the AD-081GE, this period is 8.32ms which is 198L. The exposure
time is determined by the pre-set shutter speed. If no further trigger pulses are applied,
the camera will continue in normal mode and the video signal is not output. The fast dump
readout has the same effect as “smearless readout”. Smear over highlight areas is reduced
for the trigger frame. The reset continuous trigger mode makes it possible to use triggering in
conjunction with a lens with video controlled iris.
The accumulation is LVAL Async only.
To use this mode:
Set function:
Trigger mode Reset Continuous (RCT)
Readout mode Sync, async,
Output Select 8-bit, 10-bit, 12-bit
Scanning Full/Partial
Vertical binning ON/OFF
Shutter Programmable, Exposure Time Abs
Programmable Shutter 0.5L to 792 L (1L unit)
Accumulation LVAL async
Other functions
Input: External Trigger GigE I/F,Hirose 12-pin,Hirose 6-pin
Important notes on using this mode

Trigger pulse >2 LVAL to <1 FVAL)

The minimum trigger period is;
Sync mode:
Sync Smearless time（198L）+1+ (Longer exposure time between BW1 and BW2) +
792L + 3L
Sync mode:
Async
Smearless time（198L）+1+ 792L + 3L
FVAL(792L) is the FVAL period of continuous operation.
