  • Page 27: S-Ttl Auto Mode

    Attention, to operate in s-TTL auto flash exposure mode, digital camera and ONE160x strobe must be interfaced by an optical TTL- trigger dedicated to the ONE160x unit. This device has the function of converting the information received from the camera into optical pulses, which they will be decoded by the strobe CPU to managing the monitoring pre-flashes and and the final exposure flash.

  • Page 28: Manual Mode

    ½ f-stop increments over a range of - 6 f-stop. When manual mode is selected, the default power value is Full - full power. If the digital camera is connected to the ONE160x strobe by a synchro cable with only two cabled wires (trigger+ground) and the TTL auto exposure mode is selected, the flash will be fired at full power.
  • Page 29 The ONE160x in manual exposure mode, OPT-input optical cable connection, is made to reply any pre-flash from camera, before the main exposure flash. To achieve this, ONE160x considers any very short lamp as a preflash and just reply them, waiting for the main exposure flash.
