Trigger Input Circuit
Following figure shows trigger signal input circuit of the 4-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.
