Use the 2D Barcode Reader step to decode a 2D barcode.

Main Tab

  1. In the Step Name textbox, enter a descriptive name for the step.
  2. In the Barcode Type box, select the type of 2D Barcode you want to read.
  3. Verify that the Reposition Region of Interest option is enabled if you want to link the region of interest specified in this step to a previously defined coordinate system.
  4. Link the region of interest to a coordinate system if the position of the object under inspection changes from image to image, and you need to adjust the position of the region of interest to match the new location of the object.

Settings Tab

Set the controls to specify the shape of the 2D barcode and to improve the performance of the step.

Grading Tab

Select the checkbox for the grading standard you want to use for your 2D barcodes. If you do not need grading information for your application, leave all checkboxes unselected to decrease the amount of time the step takes to complete.

The decoded characters read during the step are shown in the Code Read box.
