Barcode Processing Overview
The complete sequence of barcode processing is as follows:
1. Scanned barcode is tested for a code ID and matching length (Min/Max). If it matches, it
is processed per the rules in place for that symbology. If the scan does not meet the
criteria for that symbology, it is processed based on the settings for All. If a code ID is not
found, the barcode data is processed based on the settings for All.
criteria for that symbology, it is processed based on the settings for All. If a code ID is not
found, the barcode data is processed based on the settings for All.
2. If symbology is disabled, the scan is rejected.
3. Strip leading data bytes unconditionally.
4. Strip trailing data bytes unconditionally.
5. Parse for, and strip if found, Barcode Data strings.
6. Replace any control characters with string, as configured.
7. Add prefix string to output buffer.
8. If Code ID is *not* stripped, add saved code ID from above to output buffer.
9. Add processed barcode string from above to output buffer.
10. Add suffix string to output buffer.
11. Add a terminating NUL to the output buffer, in case the data is processed as a string.
12. If key output is enabled, start the process to output keys. If control characters are

12. If key output is enabled, start the process to output keys. If control characters are
encountered:
•
If Translate All is set, key is translated to CTRL + char, and output.
•
If Translate All is not set, and key has a valid VK code, key is output.
•
Otherwise, key is ignored (not output).
The data is ready to be read by applications.
