FUNCTIONS

External Trigger Shutter

This function is useful for the following cases.

When capturing the images according to an arbitrary external trigger

When capturing the images at same time with several cameras

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. )
