Triggers
The professional inputs can be used as trigger inputs, using an external signal to start a video acquisition. There may be a delay between the external signal occurrence and its detection and the resulting acquisition start. This delay is specified in the following table.
This delay is due to internal communication and processing time. It is independent of the TrigDelay_us parameter defined by the user.
