Reset Continuous Trigger Mode - JAI CV-M 9CL Operation Manual

6.4.6. Reset Continuous Trigger mode

The RCT mode is in principle the same as normal continuous mode. The difference is that an
external trigger pulse will immediately stop the video read out and reset and restart the vertical
timing. After a fast dump read out (198 L = 8.33ms), a new triggered exposure is started and
read out as normal. The fast dump read out is performed with a speed 4 times faster as normal.
If no further trigger pulses are applied, the camera will continue in normal mode. This fast dump
read out has the same effect as "smearless read out". Smear over highlighted areas are reduced
for the triggered frame.
The reset continuous trigger mode makes it possible to use a lens with video controlled iris
together with a triggered exposure.
For timing details, refer to fig. 13. through fig. 20. and fig. 27.

Important notes on using this mode
Trigger pulse >2 LVAL to <1 FVAL
To avoid ≤ 1 LVAL jitter in synch. accum, synchronize the trigger to LVAL.
Minimum trigger interval ≥ (exposure time + 1 FVAL + 2 LVAL + 198 LVAL).
A new trigger must not be applied before the previous triggered frame is read out.
