Triggering Example 10

SeqLength_Fr

MC_INDETERMINATE, >1

This example shows the software-controlled way to grab an arbitrarily long image of a continuous web through a line-scan camera.

The initial trigger event (TE) is directly caused by the software-issued SAS event. There can be a substantial delay between the SAS and SAP events due to the software overhead implied in opening the acquisition sequence.

Each subsequent TE event is conceptually sourced by the end of the preceding acquisition phase.

Specify the number of pages to be acquired in a row with the parameter SeqLength_Fr. To acquire an undefined number of pages, set SeqLength_Fr to MC_INDETERMINATE. In this case, the sequence will be stopped by returning the MultiCam channel to the idle state.
