Trigger Modes
The camera’s image exposures are initiated by a trigger signal The trigger event is either a
programmable internal signal used in free running mode, an external input used for
synchronizing exposures to external triggers, or a programmed function call message by the
controlling computer. These triggering modes are described below.
•
Free running (trigger disabled): The camera free-running mode has a programmable
internal timer for frame rate and a programmable exposure period.
•
External trigger: Exposures are controlled by an external trigger signal. The external
trigger signal can be either a Camera Link control line (i.e. CC [4 : 1]) or a general
purpose input (e.g. GPIO [2 : 1]. General purpose inputs are isolated by an opto-
coupler input with a time programmable debounce circuit.
•
Software trigger: An exposure trigger is sent as a control command via the Camera
Link serial communications interface. Software triggers cannot be considered time
accurate due to communications latency and sequential command jitter.
