Return To Factory Default Settings; Data Processing Overview - Honeywell MX9 Reference Manual

Return to Factory Default Settings

After scanning the engine-specific bar code to return the scanner/imager to factory default settings, the next step is to open the
bar code wedge panel on the mobile device collecting the scanned data. Click the OK button to close the panel. This action will
synchronize all scanner formats for your device. Another option you can use to reset the Data Collection panel is to scan the
LXEReset bar code (for Symbol and Hand Held Products scan engines) located in the Integrated Scanner Programming Guide.
Engine specific bar codes for integrated scanners are contained in the Integrated Scanner Programming Guide. They can be
used to set or reset scan engine parameters by scanning a bar code, then saving the change. Symbol scan engines can be
programmed using programming bar codes. Do not scan decoder engine configuration bar codes when
is on. Configuration bar codes do not decode when scanned while Continuous Scan Mode is On.

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:
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).
l
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.
