7. 5 EXT TRIG (External trigger)
Charge begins to accumulate after the trigger input, and 1 frame images are output. There are five modes: 1P SNR, 1P SR, PW SNR, PW SR, RR.
The RGB terminal trigger input and index output interface are as shown below.

*1: Externally input signal
*2: Exposure time is determined by the setting of "(1.3) Changing each setting in E.TRG mode".
*3: Video is output at the falling edge of the internal VD following completion of the exposure period. The video and the VIDEO INDEX have a paired relationship.
Note:
When the next trigger is input before completion of the output of the video corresponding to the trig- ger, there will be an effect on the video.
