GPIO Port
(B-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 24 V DC
2	Digital Input, Trigger, 0 V / 24 V
3	Ground (GND)
4	Digital Output, Flash, 0 V / 24 V

Electrical Characteristics

• Digital Input

  • Switching threshold low -> high ~6.7 V

  • Switching threshold high -> low ~6.3 V

• Digital Output

  • Voltage level low < 0.7 V

  • Voltage level high > DC_in–0.7 V

  • Maximum curent (source/sink) 30 mA
