Edge Preset Trigger Mode

In this “edge preset trigger mode”, the camera exposure starts at the rising edge of the trigger signal like the

“pulse width trigger mode” in the previous sections.

However, in this mode, the exposure duration time is based on the

preset value stored by the by the camera setting communication.
