Factory Settings
The factory setting is the camera settings that w ere shipped w ith the camera and w hich loaded during the
camera's first pow er-up. To load or restore the original factory settings, at any time, select the Factory
Setting parameter and then select the User Set Load parameter.

Trigger Modes

The camera's image exposures are initiated by a trigger event. 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 .
I nternal trigger (trigger disabled): The camera free-running mode has a programmable internal
•
timer for line rate and a programmable 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 determine the three imaging modes using a
combination of the Exposure M ode parameters (including I/ O parameters), Exposure Time and Line Rate
parameters.
