Image Acquisition Control AW0009760300072 Basler aviator GigE7.3.5 Using a Hardware Acquisition Start TriggerSignal7.3.5.1 IntroductionIf the Trigger Mode parameter for the acquisition start trigger is set to on and the Trigger Sourceparameter is set to input line 1 or line 2, an externally generated electrical signal injected into theselected source will act as the acquisition start trigger signal for the camera. This type of triggersignal is generally referred to as a hardware trigger signal or as an external acquisition start triggersignal (ExASTrig).A rising edge or a falling edge of the ExASTrig signal can be used to trigger acquisition start. TheTrigger Activation parameter is used to select rising edge or falling edge triggering.When the Trigger Mode parameter is set to on, the camera will initially be in a "waiting for acquisitionstart trigger" acquisition status. It cannot react to frame start trigger signals when in this acquisitionstatus. When the appropriate ExASTrig signal is applied to the selected source (e.g, a rising edgeof the signal for rising edge triggering), the camera will exit the "waiting for acquisition start trigger"acquisition status and will enter the "waiting for frame start trigger" acquisition status. It can thenreact to frame start trigger signals. When the number of frame start trigger signals received by thecamera is equal to the current Acquisition Frame Count parameter setting, the camera will return tothe "waiting for acquisition start trigger" acquisition status. When a new ExASTrig signal is appliedto the selected source, the camera will again exit from the "waiting for acquisition start trigger"acquisition status and enter the "waiting for frame start trigger" acquisition status.For more information about setting the camera for hardware acquisition start triggering andselecting the input line to receive the ExASTrig signal, see Section 7.3.5.3.For more information about the electrical requirements for input line 1 and line 2, see Section 5.7on page 38.
