After executing the AcquisitionStart command, the camera waits for a trigger signal, which may be a
software trigger or a hardware trigger of the camera. Each time the camera receives a trigger signal, it can
acquire a frame of image until the AcquisitionStop command is executed. It is not necessary to execute
the AcquisitionStart command every time.

When the trigger mode is set to On, the trigger type is FrameBurstStart
After executing the AcquisitionStart command, the camera waits for a trigger signal, which may be a
software trigger or a hardware trigger of the camera. Each time the camera receives a trigger signal, it can
continuously acquire the set AcquisitionFrameCount frames of image. If the AcquisitionStop command is
received during the acquisition process, the image being transmitted may be interrupted, resulting in the
number of images acquired this time not reaching the AcquisitionFrameCount frames of image (except for
ME2L series).
3)
When the trigger mode is set to Off
After executing the AcquisitionStart command, the camera will continuously acquire images until it receives
the AcquisitionStop command.
You can check if the camera is in the waiting trigger status by the camera's trigger wait signal or
by using the acquisition status function.

Trigger Type Selection
Two camera trigger types are available: FrameStart and FrameBurstStart. Different trigger types
correspond to their respective set of trigger configurations, including trigger mode, trigger delay, trigger
source, trigger polarity, and software trigger commands.
FrameStart trigger mode
The FrameStart trigger is used to acquire one image. Each time the camera receives a FrameStart trigger
signal, the camera begins to acquire an image.

FrameBurstStart trigger mode
You can use the FrameBurstStart trigger signal 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 1~65535, and the default value is 1.
