Image Acquisition ControlBasler scout 857.4 The Acquisition Start Trigger inStandard ModeFor more information about standard mode and legacy mode and how to set them, see Section 7.1on page 77.The acquisition start trigger is used in conjunction with the frame start trigger to control theacquisition of frames. In essence, the acquisition start trigger is used as an enabler for the framestart trigger.When the acquisition start trigger is enabled, the camera’s initial acquisition status is "waiting foracquisition start trigger". When the camera is in this acquisition status, it will ignore any frame starttrigger signals it receives. If an acquisition start trigger signal is applied to the camera, it will exit the"waiting for acquisition start trigger" acquisition status and enter the "waiting for frame start trigger"acquisition status. In this acquisition status, the camera can react to frame start trigger signals andwill begin to expose a frame each time a proper frame start trigger signal is applied.A primary feature of the acquisition start trigger is that after an acquisition start trigger signal hasbeen applied to the camera and the camera has entered the "waiting for frame start trigger"acquisition status, the camera will return to the "waiting for acquisition start trigger" acquisitionstatus once a specified number of frame start triggers has been received. Before more frames canbe acquired, a new acquisition start trigger signal must be applied to the camera to exit it from"waiting for acquisition start trigger" status. Note that this feature only applies when the TriggerMode parameter for the acquisition start trigger is set to on. This feature is explained in greaterdetail in the following sections.This section only applies if the standard mode is enabled for image acquisitioncontrol.When the camera is started for the first time after delivery from the factory theimage acquisition control will not be in standard mode but in legacy mode.Use the legacy mode only if you want to operate the camera together withprevious cameras not featuring the standard mode.
