This parameter applies to the hardware line designated by LineTrigLine when LineRateMode is set to PULSE or CONVERT.
Along with LineTrigCtl and LineTrigEdge, 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 LineTrigFilter parameter reduces the noise sensitivity over the line trigger pulse usually issued by a motion encoder.
The time constant of the filter is the amount of time the line should be detected at the same logic state before a logic transition be considered.
When LineTrigLine is an insulated I/O, LineTrigFilter is forced to STRONG.
