Notes for trigger pulse input timing
The next trigger pulse can be input while reading out signals. However, please do not input a trigger pulse which ends its
exposure while reading out the prior signals. In other words, a trigger pulse, while reading out signals for the prior frame and
starts reading out signals for the next frame, cannot be input.
When a trigger is input with the restricted timing explained the above, or with the timing to end exposure right after FVAL
becomes “L”, video output from the camera might be stopped. In such case or when proper image data cannot be output,
execute “SensorReset” command after trigger input is stopped to re-start camera operation.
※
In case of when camera does not start operating, please reboot the camera.
