Inputting trigger and pulse conditions

<Inputting method>

Input external triggers to the “TRIG IN” connector on the rear panel of the camera using the 4-pin connector provided.

As shown in the figure, the pin 3 is the “Trigger Input” and the pin 2 is the “GND”. Design the cable accordingly.

<Pulse conditions>

The input pulse is a 5 V negative polarity pulse. Although the falling edge of the signal is detected as the start of trigger, the

pulse width must be set 1 ms or more.

The trigger can be also applied by setting the pin 3 “Trigger Input” to the pin 2 “GND”. (Take note of chattering at this time.)
