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 exceed +15V DC, to avoid damage to the

internal ESD protection and the optocoupler!
