First rising edge trigger
Object # 1, moving in front of the detector beam, causes
the first trigger (rising edge trigger) signal to be sent to the
scanner, initiating the read cycle.
Subsequent rising edge trigger
Object # 2, moving in front of the detector's beam, causes
a second trigger (rising edge trigger) signal to be sent to
the scanner. This signal initiates a new read cycle and
ends the previous read cycle provided that New Trigger or
Timeout and New Trigger is enabled and a good read or
timeout has not already occurred.
