Principle
When the level signal sent by
external devices is in rising edge,
the camera receives trigger signal
and starts to acquire images.
When the level signal sent by
external devices is in falling edge,
the camera receives trigger signal
and starts to acquire images.
Level High refers to the level high
of the trigger signal is valid. As
long as trigger signal is in level
high, the camera keeps exposure
and acquisition status.
Level Low refers to the level low of
the trigger signal is valid. As long
as trigger signal is in level low, the
camera keeps exposure and
acquisition status.
