13-5-2 TRIGGER IN TIMINGS
Input the external trigger pulse when the camera is operated in External Control mode. The
signal level is TTL level or C-MOS 3.3 V level (Termination is 680
Ω
), and the external trigger
pulse polarity can be set either to negative or positive. Minimum trigger pulse width is 1 µs in
edge trigger mode and synchronous readout trigger mode or 100 µs in level trigger mode.
The maximum trigger pulse width is 10 s in all modes. Regarding the fastest frame rate, see
the fastest frame rate table in the chapter [13-1.CAMERA SPECIFICATIONS].
The normal operation is not warranted if the input trigger pulse condition is not in the above
conditions.
