Data Processing Overview
Bar code data processing involves several steps. Some steps may be skipped during the processing depending on user
selections on the Symbology Settings panels. The steps are presented below in the order they are performed on the scanned
data.
1. Scanned data is tested for a
code ID
and 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 bar code data is processed based on the settings for All.
2. If the 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,
Data Options
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
data 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 encountered:
l
If Translate All is set, key is translated to CTRL + char, and output.
l
If Translate All is not set, and key has a valid VK code, key is output.
l
Otherwise, key is ignored (not output).
13. If key output is disabled, a windows message is broadcast to notify listening applications that data is available.
The manipulated data is ready to be read by applications.
