# IO Output

On the Trigger tab, the IO Output section provides parameters which allow you to control the general input and output signals of the camera.

Note:

The displayed features vary with different camera models. This topic only introduces common IO Output features.

Line Selector

  Selects the physical line (or pin) of the external device connector or the virtual line of the Transport Layer to configure its parameters such as line mode.

Line Mode

  Control if the selected line is used to input signals, output signals, or control lights.

  Input

    Use the selected line to input signals.

    Line Debouncer Time

      Set a debouncer time (range: 0 to 1000000, unit: μs) to filter out invalid short signals (i.e.,contact bouncing signals). Once you set a debouncer time, signals that do not last longer than the time will be ignored.

  Strobe

    Used the selected line to output signals to control light source of the camera.

    Line Source
      Exposure Start Active

        If the exposure starts, the output signals for controlling the light will be triggered.

      Acquisition Start Active

        If acquisition starts, the output signal for controlling the light will be triggered.

      Acquisition Stop Active

        If acquisition stops, the output signal for controlling the light will be triggered.

      Frame Burst Start Active

        If the burst of a frame starts, the output signal for controlling the light will be triggered.

      Frame Burst Stop Active

        If the burst of a frame stops, the output signal for controlling the light will be triggered.

      Soft Trigger Active

        Trigger the output signal for controlling the light via the Software.

      Hard Trigger Active

        Trigger the output signal for controlling the light via the camera.

      Counter Active

        Trigger the output signal for controlling the light by the counter.

      Timer Active

        Trigger the output signal for controlling the light by the timer.

    Strobe Enable

      Enable the strobe mode.

    Strobe Line Duration

      Set the time duration (unit: μs) of the output signal for controlling the light.

    Strobe Line Delay

      Set the delay time (unit: μs) for triggering the output signal for controlling the light if the events defined in Line Source occur.

    Strobe Line Pre Delay

      Set the pre delay time (unit: μs) for triggering the output signal for controlling the light if the events defined in Line Source occur.
