Trigger Notes:

  • Recommendation: USE PIN 5 as Trigger and 7 as Strobe output.

  • GND is common for power, trigger +strobe

  • To initiate a TTL trigger, apply a min voltage of 5 V 

  • A 2µsec pulse will trigger the camera reliably as long as the pulse width jitter is less than 1 µsec

Basic circuits for Hardware Interfacing


  • Use Hardware trigger connection on N1

  • For Strobe use OUT1
