Linescan Triggers
External triggers allows line acquisition to be synchronized to external events. When acquiring a line
in External Trigger mode, the acquisition will not start until the PC2-CamLink receives a trigger
signal. Acquisition begins with the next valid line after the trigger.
Two trigger events, the shaft encoder or a user timer, can fire the EXSYNC and PRIN pulse generators
for linescan cameras.
Linescan acquisition relies on the concept of virtual frames to simplify transfer to the host. Basically, a
virtual frame is defined as a number of consecutive lines that are grouped together into a single host
buffer.
