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 line 1 (e.g, a rising edge of the signal forrising edge triggering), the camera will exit the "waiting for acquisition start trigger" acquisitionstatus and will enter the "waiting for frame start trigger" acquisition status. It can then react to framestart trigger signals. When the number of frame start trigger signals received by the camera is equalto the current Acquisition Frame Count parameter setting, the camera will return to the "waiting foracquisition start trigger" acquisition status. When a new ExASTrig signal is applied to line 1, thecamera will again exit from the "waiting for acquisition start trigger" acquisition status and enter the"waiting for frame start trigger" acquisition status.
