6.2 Acquisition Start and Stop Commands
and the Acquisition Mode
Executing an Acquisition Start command prepares the camera to acquire frames. You must execute
an Acquisition Start command before you can begin acquiring frames.
Executing an Acquisition Stop command terminates the camera's ability to acquire frames. When
the camera receives an Acquisition stop command:
If the camera is not in the process of acquiring a frame, its ability to acquire frames will be

terminated immediately.
If the camera is in the process of acquiring a frame, the frame acquisition process will be

allowed to finish and the camera's ability to acquire new frames will be terminated.
The camera's Acquisition Mode parameter has two settings: Single Frame and Continuous. The
use of Acquisition Start and Acquisition Stop commands and the camera's Acquisition Mode
parameter setting are related.
If the camera's Acquisition Mode parameter is set to Single Frame, after an Acquisition Start
command has been executed, a single frame can be acquired. When acquisition of one frame is
complete, the camera will execute an Acquisition Stop command internally and will no longer be
able to acquire frames. To acquire another frame, you must execute a new Acquisition Start
command.
If the camera's Acquisition Mode parameter is set to Continuous, after an Acquisition Start
command has been executed, frame acquisition can be triggered as desired. Each time a frame
trigger is applied while the camera is in a "waiting for frame trigger" acquisition status, the camera
will acquire and transmit a frame. The camera will retain the ability to acquire frames until an
Acquisition Stop command is executed. Once the Acquisition Stop command is received, the
camera will no longer be able to acquire frames.
