This demo opens the device, stops any current running schedule,
sets the ram/buffer for our update synchronization on video signal,
and starts right away.
The arguments of DPxSetDoutSched(onset, rateValue, rateUnits, count) are as follow:
Onset: 0, starts now.
Rate: 2, on/off happens once per frame.
Units: 'video', per video frame.
Duration: 0, lasts until the schedule is stopped.
