Image Acquisition ControlBasler scout 937.5.1 Frame Start Trigger Mode (Standard Mode)The main parameter associated with the frame start trigger is the Trigger Mode parameter. TheTrigger Mode parameter for the frame start trigger has two available settings: off and on.7.5.1.1 Frame Start Trigger Mode = OffWhen the Frame Start Trigger Mode parameter is set to off, the camera will generate all requiredframe start trigger signals internally, and you do not need to apply frame start trigger signals to thecamera.With the trigger mode set to off, the way that the camera will operate the frame start trigger dependson the setting of the camera’s Acquisition Mode parameter: If the Acquisition Mode parameter is set to single frame, the camera will automatically generatea single frame start trigger signal whenever it receives an Acquisition Start command. If the Acquisition Mode parameter is set to continuous frame, the camera will automaticallybegin generating frame start trigger signals when it receives an Acquisition Start command.The camera will continue to generate frame start trigger signals until it receives an AcquisitionStop command.The rate at which the frame start trigger signals are generated will be determined by thecamera’s Acquisition Frame Rate Abs parameter: If the parameter is not enabled, the camera will generate frame start trigger signals at themaximum rate allowed with the current camera settings. If the parameter is enabled and is set to a value less than the maximum allowed framerate with the current camera settings, the camera will generate frame start trigger signalsat the rate specified by the parameter setting. If the parameter is enabled and is set to a value greater than the maximum allowed framerate with the current camera settings, the camera will generate frame start trigger signalsat the maximum allowed frame rate.For information about setting the Acquisition Frame Rate Abs parameter, see Section 7.5.1.3 onpage 95.Exposure Time Control with the Frame Start Trigger OffWhen the Trigger Mode parameter for the frame start trigger is set to off, the exposure time for eachframe acquisition is determined by the value of the camera’s Exposure Time Abs parameter.For more information about the camera’s Exposure Time Abs parameter, see Section 7.7 onpage 116.Keep in mind that the camera will only react to frame start triggers when it is in a"waiting for frame start trigger" acquisition status. For more information about theacquisition status, see Section 7.2 on page 79 and Section 7.4 on page 85.
