Outputs: Triggering a Light for Image Acquisition

The rising or falling edge of the signal can be used to trigger a strobe.

To send a signal to trigger a strobe:

  1. Define the acquisition trigger settings in the Set Up Image step. Ensure the exposure time is 0.50 ms greater than the strobe pulse duration specified on the external lighting device.
  2. Set the Signal Type of the output line to Strobe.
  3. Press the Details button and specify if the strobe is to be triggered by the Rising Edge or Falling Edge of the signal.
    • NPN Configuration: If set to Rising Edge, the signal is HIGH when the image sensor is being exposed, otherwise the signal is LOW. If set to Falling Edge, the signal is LOW when the image sensor is being exposed, otherwise the signal is HIGH. The Exposure time must be 0.50 ms greater than the strobe pulse duration specified on the external strobe device.

    • PNP Configuration: If set to Rising Edge, the signal is LOW when the image sensor is being exposed, otherwise the signal is HIGH. If set to Falling Edge, the signal is HIGH when the image sensor is being exposed, otherwise the signal is LOW. Always pulsed for the duration of the exposure. The Exposure time must be 0.50 ms greater than the strobe pulse duration specified on the external strobe device.

      Note:
      • For the In-Sight 5600 series, 5705, 5705C, 5715 and 9902L vision systems, the strobe behavior is inverted (i.e., for NPN wiring configurations, the Rising Edge and Falling Edge behave like a PNP configuration).
      • If using a strobe with the In-Sight 9902L line scan vision system:
        • The strobe should use a PNP wiring configuration and the Strobe/Light Control Trigger should be set to Rising Edge.
        • When the vision system receives an acquisition trigger, the output line sends a pulse and the strobe flashes for the duration of the Exposure time. Once exposure is complete, there must be a minimum of 100µs before the next acquisition trigger is received or the strobe might not function correctly.
  4. Specify the Strobe Start Position. This option is not supported for the In-Sight 9902L vision system.
    • Acquisition Start: Specifies that the strobe will pulse as the vision system begins its acquisition. Supported on all models except the In-Sight 8405 vision system.
    • Camera Trigger: Specifies that the strobe will pulse upon receiving a camera trigger event. Supported on all models except the In-Sight 8405 vision system.
    • All Rows Exposed: Specifies that the strobe will pulse only when all pixel rows are exposed. Supported on the In-Sight 8405 vision system only.
Note:
  • The In-Sight vision system and lighting device must be connected to the same ground for the lighting device to operate correctly.
  • The In-Sight Micro 1000 series, In-Sight 5000 series (except the 5604), In-Sight 7000 Gen2 series, In-Sight 8000 series and In-Sight 9000 series vision systems support the Strobe signal type for the HSOUT 1 line.
  • The In-Sight 70xx - 74xx series vision system supports the Strobe signal type for the HSOUT 0 line.
  • For the In-Sight 8405 vision system, the Strobe Start Position is fixed to All Rows Exposed and the output signal is pulsed only during the time that all pixel rows are exposed. If using a strobe with the In-Sight 8405 vision system, a minimum Exposure value of 72ms is recommended for a full frame image capture, to ensure that all pixel rows are exposed when the strobe is pulsed.

The rising or falling edge of the signal can be used to trigger an external light.

To send a signal to trigger an external light: 

  1. Log onto an In-Sight 5000 series vision system and connect to a CIO-1460 I/O module.
  2. Define the acquisition trigger settings in the Set Up Image step. Ensure the exposure time is 0.50 ms greater than the strobe pulse duration specified on the external lighting device.
  3. Set the Signal Type for HSOUT 1 to Light Control.
  4. Press the Details button and specify if the strobe is to be triggered by the Rising Edge or Falling Edge of the signal.
Note:
  • The In-Sight vision system and lighting device must be connected to the same ground for the lighting device to operate correctly.
  • This output type is only valid for High Speed Output line 1 (HSOUT 1) when configuring the CIO-1460 I/O module for the In-Sight 5000 series vision system.
