6.2.2. Trigger Mode
After a specified external event (trigger) has occurred, image acquisition is started. De-
pending on the interval of triggers used, the camera operates non-overlapped or over-
lapped in this mode.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:

6.2.2.1. Overlapped Operation: t
In overlapped operation attention should be paid to the time interval where the camera is
unable to process occuring trigger signals (t
exposures. When this process time t

After t
