Trigger Modes

The camera's im age exp osu res are initiated by a trigger event. The trigger event is either a program mable
internal signal u sed in free running mod e, an external input u sed for synchronizing exposures to external
triggers, or a programmed function call message by the controlling computer. These triggering m od es are
d escribed below .

Internal trigger (trigger disabled): The camera free-ru nning mod e has a program mable internal
timer for line rate and a programm able exposure period .

External trigger (trigger enabled): Exposures are controlled by an external trigger signal. The
external trigger signal is the Camera Link control line CC1.

Exposure Controls

Exposure Control modes define the method and timing of how to control the sensor integration period.
The integration period is the amount of time the sensor is exposed to incoming light before the video
frame data is transmitted to the controlling computer.

Exposure control is defined as the start of exposure and exposure duration.

The start of exposure can be an internal timer signal (free-running mode) or an external trigger
signal.

The exposure duration can be programmable (such as the case of an internal timer) or controlled by the
external trigger pulse width.
The camera can grab images in one of three w ays. You d etermine the three im aging mod es using a
combination of the Exposure Mod e parameters (includ ing I/ O param eters), Exposure Time and Line Rate
parameters.
