FrameBurstStart trigger mode
You can use the frame burst trigger to acquire a series of images ("continuous shooting" of the image).
Each time the camera receives a FrameBurstStart trigger signal, the camera will start acquiring a series
of images. The number of acquired image frames is specified by the "Acquisition burst frame count"
parameter. The range of "Acquisition burst frame count" is 1~255, and the default value is 1.
For example, if the "Acquisition burst frame count" parameter is set to 3, the camera automatically acquires
3 images. Then, the camera waits for the next FrameBurstStart trigger signal. After receiving the next
trigger signal, the camera will take another 3 images, and so on.

Figure 8-15 FrameBurstStart trigger
FrameStart trigger mode and FrameBurstStart trigger mode set to ON at the same time
The FrameStart trigger mode and FrameBurstStart trigger mode can be set to ON at the same time. The
camera will not acquire images immediately after receiving a FrameStart/FrameBurstStart trigger signal.
The camera will wait for several FrameStart trigger signals after receiving the FrameBurstStart trigger
signal and acquires images under the control of the FrameStart trigger signal. The number of acquired
image frames is specified by the "Acquisition burst frame count" parameter.
For example, if the "Acquisition burst frame count" parameter is set to 3, after receive the FrameBurstStart
trigger signal, the camera will wait for 3 FrameStart trigger signals and acquires 3 images. The remaining
FrameStart trigger signals will be discarded, and so on.
