Fixed Trigger Shutter Mode
□
This is the mode to start exposure with external input trigger signals, and set the exposure time with serial
commands.
□
Trigger operation is H Sync, and V-sync Reset system. The delay time (Exposure Time Delay) from
detecting
trigger edge in the camera to actually starting exposure is 2H ~ 3H.
Since the external trigger signals synchronize with camera internal H signals, 1H jitter occurs to Exposure Time Delay.
The trigger pulse with the minimum 1H and more shall be input (Please refer to the table below for the details of 1
line width).

There is an exposure time period for approx. 14.26μs at the edge right after exposure output.
□
Triggers can be accepted while outputting video output images. However, please be noted that a trigger signal to
start the next video outputting should not be input before completion of outputting the prior images.
□
Trigger input during exposure time shall be ignored in the camera. (Refer to (A) in the drawing below).
Please note that a trigger shorter than 1 frame cycle shall not be used.
