Code Reader Impact Reference Guide
Datalogic Automation Inc. 3-178
The following example shows two filters. The first one will pass only if the image contains two Datamatrix
ECC200 codes (Min # = 2) that start with the string "728" (Match String = 728*). The second filter will pass
if the image contains any UPC-A code (Match String = *). The first filter fails because the image contains
only one Datamatrix ECC200 code (Act # = 1) that has a string that starts with "728." Because the first filter
fails, the tool fails.
10. Click the Grades radio button to view code quality grades that were generated for each found code.
(You must have selected the Enable Verification Grading check box in step 5.)
Training Codes from Multiple Images
If you want to find different code types, and they are not all in one image, you can train the tool using multi-
ple images.
1. Snap a good image of the desired code or codes you want to train, 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.
3. Select the Train Mode Add.
4. Select the Code Type.
The Datamatrix filter failed
because the number of codes
found (Act #) was less than the
minimum wanted (Min #)
The tool failed because one
of the filters failed (the Data-
matrix filter)
In the image window, green
ROIs show all found codes, including
those that passed or failed a filter.
