Reset Continuous Trigger (Rct) Mode - JAI AD-131GE User Manual

10.6.6

Reset Continuous Trigger (RCT) mode

The RCT mode operates like EPS (edge pre-select) 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
readout is performed. In the AD-131GE, this period is 6.34ms which is 196L. 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 appearing above 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:
Input:
This function can be set by selecting RCT mode in Exposure mode of JAI Acquisition Control.
However, Acquisition Mode, Sync Mode, Exposure Time, and so on should be set.
Important notes on using this mode
The minimum duration of the trigger is 2 LVAL. The minimum period of the trigger input

is the following.
Sync mode:
Async
Note: If the next trigger is input during the output of transfer signal, this output signal is
immediately stopped and thrown away by the High Speed Transfer operation.
In the RCT operation mode, only when Sync mode is async and accumulation mode is

LVAL async , RCT mode is available.
