Trigger mode maximum frame rate: The maximum frame rate of camera when FrameStart or
FrameBurstStart is ON. Default full frame and short exposure time, and camera is not limited by interface
bandwidth at this time.
Acquisition burst mode permissible frames: To ensure that frame dropping could not occur, the maximum
number of trigger signals (FrameStart ON / FrameBurstStart OFF and frame rate is equal to trigger mode
maximum frame rate) or the maximum high-speed burst frames (FrameStart OFF / FrameBurstStart ON
and camera is under FrameBurstStart trigger mode) of camera.
When the user sends the trigger signal to the camera at a frequency lower than the maximum
frame rate of trigger mode, the permissible frame number for acquisition burst will be increased.

Software Trigger Acquisition and Configuration
Software trigger acquisition configuration
The camera supports software trigger acquisition mode. Three steps followed should be ensured.
1)
Set the Trigger Mode to ON.
2)
Set the Trigger Source to Software.
3)
Send Software Trigger command.
All the software trigger commands are sent by the host through the USB3.0 bus, to trigger the camera to
acquire and transmit images.
