Trigger Mode Details
Genie Nano image exposures are initiated by an event. The trigger event is either the camera’s
programmable internal clock 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 Mode=Off): The Nano free-running mode has programmable
internal timers for frame rate and exposure period. Frame rate minimums, maximums, and
increments supported are sensor specific. Maximum frame rates are dependent on the
required exposure.
•
External trigger (Trigger Mode=On): Exposures are controlled by an external trigger
signal where the specific input line is selected by the Trigger Source feature. External
signals are isolated by an opto-coupler input with a time programmable debounce circuit.
