How to Set Up the Code Reader tool
1. Snap a good image of the desired code or codes you want to read, then click the Setup tab.
2. Click the ROI radio button. Position the ROI over the code or codes. Be sure that the ROI completely
encloses the desired codes. See “Shape List ROI Toolbar” on page 3-18.
3. Select the Train Mode.
Add: When the tool is trained, any new code types trained are added to the list of trained codes. Any
existing code types stay in the list, even if they are not trained in the image again. (Also see “Training
Codes from Multiple Images” on page 3-178.)
Replace: When the tool is trained, any new code types trained in the image are added to the list of
trained codes and any existing code types that are not trained are removed from the list.
4. Select the Code Type. When the tool is trained, it enables codes of this type that it finds in the image.
When the tool runs it looks for and inspects enabled codes. For more details about code types, see
“How the Code Reader Tool Works” on page 6-34.
5. If you want the tool to generate code quality grades for each code found, select the Enable Verification
Grading check box. The codes are displayed on the Grades panel in the Setup tab. See “Code Quality
Grades” on page 6-39.
6. Enter the Minimum Number of Codes to Train. This is the minimum number of code configurations
the tool uses during training. The tool stops training after it tries this number of configurations, though
it may find more than this number of individual code instances. A configuration includes at least the
following parameters: Minimum Number of Codes to Train, Type, whether Verification Grading is
enabled, the Mode selected, and the Processing Mode selected.
7. Click the Train button. Depending on the configuration and the number of codes in the image, training
may take several seconds. When it is complete, an ROI is drawn around each found code, and those
codes are enabled in the Code Type window.
To restart the Train process, click the Reset button and begin again with step 2. Reset will clear all the
enabled codes and resets all the train configurations to the default selections.

A list of the Actual number of codes found and passed based on the
Pass Fail group of Input Property settings. See “Using the Pass Fail Fil-
ters” on page 3-179.
Unicode Output
String
If the found code contains any text with ISO-8859-1 encoding, this string
provides it in UTF-8 format.
