Triggering and Strobe through Power Connector
The Power Connector on FX Series cameras is not only for powering the camera but has also pins for Trigger input
and Strobe signal output. This chapter offers a brief introduction to external triggering. For more detailed description,
refer to technical note TN_58 - Trigger and Strobe with FX10 and FX17.

Trigger input
The Trigger Input on FX Series cameras is opto-isolated. Trigger Input is pin #8 ISO_TRIGGER. Use pin #6
ISO_GND as a ground signal. Trigger signal input range is with 5 to 15 VDC. Acceptable minimum Trigger Input
pulse width is 0.2 us. Maximum pulse width is half of frame period. For example, with 100 fps the half would be 5
ms.
Note:
The trigger input is equipped with a constant current diode which limits the current of the optocoupler
over a wide range of voltage. Trigger signals can thus directly get connected with the input pin and there is no
need for a current limiting resistor, that depends with its value on the input voltage.
Caution:
The input voltage to the ISO_TRIGGER pin must not 15V DC, to avoid damage to the
internal ESD protection and the optocoupler!
