Parameter Description

This parameter applies to the hardware line designated by LineTrigLine when LineRateMode is set to PULSE or CONVERT.

Along with LineTrigCtl and LineTrigFilter , it declares the grabber attributes of the terminal sensing the line trigger pulse. The line trigger pulse is processed by the grabber and transferred to the camera as the line reset pulse.

The LineTrigEdge parameter determines the significant edge of the line trigger pulse usually issued by a motion encoder.
