Ricoh FV-G200B1 manual 15/38

3.4Edge Preset Trigger Mode (Trigger input while the image is out)

In this trigger mode, the camera exposure starts at the rising edge of the trigger pulse.

If trigger signal input is required while the image is out, then it is necessary to disable the trigger signal mask with the communication.

To avoid generating additional noise on the image, it is necessary to set the “H reset” at the exposure start mode.
