Trigger input (pin 10-11)
The current through the optocoupler’s LED should be in the range from 5 mA to
15 mA. This is the case if 5.0 V ≤ V
in
≤ 12 V.
A rising edge at this optocoupler input starts the exposure. It depends on the
trigger input selection T and the current trigger mode M whether this input is
enabled and how it controls the exposure time.
The optocoupler adds a typical delay of about 0.1 μs to the externally applied
signal.
For more information on the various trigger and exposure modes: see chapter

Note
If you use higher voltages, you have to connect externally an
additional current limiting resistor.
