10.4.21 SetTriggerMode
Configures the camera trigger mode.
Value Mode
0 Internal (Periodic, period determined by SetPeriodLo, SetPeriodHi)
1 External (Periodic, period determined by SetPeriodLo, SetPeriodHi)
2 External PWM mode (exposure time determined by trigger pulse width)
In all modes the frequency of the trigger must not exceed 30Hz for “low” clock mode or 60Hz for
“high” clock mode.
In mode 2 the pulse width of the trigger (exposure time) must be at least 2ms shorter than the
trigger period. In other words, the trigger pulse must be “low” for at least 2ms. This places an
upper limit on the exposure time.
