Trigger Input Circuit
The following figure shows trigger signal input circuit of the 6-pin connector. Transmitted trigger signal is applied
to the internal circuit through a photo coupler. Minimum trigger width that can be recognized by the camera is 1
㎲. If transmitted trigger signal is less than 1 ㎲, the camera will ignore the trigger signal. External trigger circuit
example is shown below.
