GPIO Port
(S-Series)

The GPIO port uses a 4-pin male M8 connector providing power input and trigger/flash input and output.

Note

The trigger and flash signals are ground referenced and push-pull driven.

Pin Assignment

1	Power Supply Input 12-24V DC, 1A
2	Digital Input, Trigger, 0V / 24V
3	Ground (GND)
4	Digital Output, Flash, 0V / 24V

Electrical Characteristics

• Digital Input

  • Switching threshold low -> high ~6.0V

  • Switching threshold high -> low ~5.7V

• Digital Output

  • Voltage level low < 0.7V

  • Voltage level high > DC_in - 0.7V

  • Maximum curent (source/sink) 30mA
