Trigger/Sync Mode
The default state of the camera at start-up is in the Internal/continuous mode. In this mode
the camera does not require a trigger input signal. The other camera modes (External Edge
High, Edge Low, Pulse High and Pulse Low) require an external trigger input. In these modes
the camera waits for a trigger signal to initiate the acquisition of a frame. There is a delay
(latency) between the trigger event and the start of an acquisition of 12 microseconds.
