PLC/Logical Operation on Inputs
The logic input combines trigger signals with Boolean algorithms. The
camera provides AND, NAND, OR, NOR as below. You might combine
combine true/false states of the inputs to determine camera actions. The
result can be connected to a camera trigger signal or it may be source for
the next logical operation with another input. It is possible to connect it to
an OUT line as well.
AND
Both trigger inputs have to be true.

NOR
No trigger input – one nor two – results in a high or a low level
pulse_out.
Invert both trigger inputs. By inverting the resulting pulse_out you will get
the NOR I pulse
