Asynchronous Software Triggering

Shutter integration can be initiated by a software trigger by setting the Trigger Source to Software in the GenICam
features.
The time from a software trigger initiation to the start of shutter is shown below:
The time from when the software trigger is written on the camera to when the start of integration occurs can only be
approximated. We then add the trigger latency (time from the trigger pulse to the start of integration) to this.

Figure 7.11: Software trigger timing
This timing is solely from the camera perspective. It is virtually impossible
to predict timing from the user perspective due to latencies in the
processing of commands on the host PC.
