Rolling Shutter External Triggering (Non Overlap Mode)
In this section, both External and Software Trigger are described in the same diagram as the acquisition sequence is the same. The trigger event can either be from the EXT Trigger input or sent via software. The ARM signal is asserted to indicate it is ready to detect an incoming trigger input.
Once the trigger event is detected a rolling reset is initiated, this effectively begins a new exposure. When the exposure period has completed, a signal frame read out phase begins. Once the frame has been read out completely the Arm signal goes high and the camera waits for the next trigger event to be detected.
The external trigger is fed via the EXT Trigger input on the I/O Connector on the camera head.
