Mode 3: External Trigger with Maximum Exposure
Frame rate is set by the period of the external trigger pulses. Since there is no electronic
shuttering, any trigger pulses faster than the readout time are ignored. The falling edge of
the external trigger marks the beginning of the exposure.
Example 2: Frame Rate is set by External Trigger Pulses.

Mode 4: Smart EXSYNC, External Frame Rate and
Exposure Time
In this mode, the external trigger rate sets both the frame rate and the exposure time. The
rising pulse of the external trigger marks the beginning of the exposure.
Note: At the end of the exposure time, the collected data will be transferred to the read
out area only if it is not already in the process of reading out. If readout is already in
process, the exposure time will be extended until the readout has finished, as is illustrated
in Example 4.
Example 3: Trigger Period is Repetitive and Greater than Readout Time.
