6.3.4 Reset Continuous (RCT) trigger mode
The RCT mode operates like EPS (edge preselect) mode with smearless function. An
external trigger pulse will immediately stop the video read out, reset and restart the
exposure, then operate as normal mode until the next trigger. After the trigger pulse is
input, a fast dump read out is performed. In the CM-040MCL/ CB-040MCL, this period is
6.77ms which is 215L. 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 read out has the same effect as “smearless read out”.
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.
To use this mode:
Set function:
Trigger mode

Important notes on using this mode
Trigger pulse >2 LVAL to <1 FVAL)
Note: When PE is set at 596 or the shutter is set at OFF, EEN is always HIGH.
