Parameter Description

The delay is expressed as a number of video lines when the scanning method is progressive. It is expressed in half-lines when the scaming method is interlaced.

This parameter applies to analog area-scan cameras delivering a separate vertical synchronization pulse used by the frame grabber to monitor the camera timing (digital synchronization mode).If this pulse is not available, the vertical synchronization embedded in the composite video signal is used instead (analog synchronization mode). In this case, the VCsyncAft_Ln parameter is significant. The delay is counted from the leading edge of the vertical synchronization pulse delivered by the camera.

This parameter applies to Camera Link area-scan cameras. In that case, the delay is counted from the leading edge of the FVAL pulse delivered by the camera.
