80
16 not starting with 414, 419, 434 or 439. Tries to scan the supplemental if it is present. If the 
supplemental scanning failed, then the main barcode is returned.
• Supplemental 977 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 977. 
Disables reading of supplementals for another UPC/EAN barcode not starting with 977. Tries to scan 
the supplemental if it is present. If the supplemental scanning failed, then the main barcode is returned.
Reader Params
Allows the configuration of parameters specific to the selected barcode reader.
NOTE:  Not all parameter options are available with all scanners. See the DataWedge app on each device for the available
scanners and parameter options.
• Character Set Configuration - Used to support the GB2312 Chinese characters encoding.
• Character Set Selection - Allows the user to convert the barcode data if different from default encoding 
type.
• Auto Character Set Selection (Best Effort) - Automatic character convert option. Tries to decode 
data from the Preferred selection. The first correct decodable character set is used to convert the 
data and is sent.
• ISO-8859-1 - Part of the ISO/IEC 8859 series of ASCII-based standard character encodings. It is 
generally intended for Western European languages.
• Shift_JIS - Shift Japanese Industrial Standards (JIS) is a character encoding for the Japanese 
language.
• GB18030 - Chinese coded character set that defines the required language and character support 
necessary for software in China.
• UTF-8 - A character encoding capable of encoding all possible characters, or code points, defined by 
Unicode (default).
• Auto Character Set Preferred Order - In Auto Character Set Selection mode, the system will try to 
decode the data in a preference order of character sets. The algorithm used is a best effort one. That is, 
there could be cases where the data can be decoded from more than one character set. The first 
character set from the preferred list which can decode the data successfully will be chosen to decode 
the data and sent to the user. Any other character set that is in the list but lower in the preferred order, 
would not be considered, even if the data could be successfully decoded using such character set.
The preferred character set and its preference order is configurable to the user through the Auto 
Character Set Preferred Order menu. Users can change the order by dragging the icon for that menu 
item. To delete an item, long press on an item and the Delete option will appear. To add a new item, tap 
the menu icon at top right corner and options to add UTF-8 and GB2312 will appear.
• UTF-8 - A character encoding capable of encoding all possible characters, or code points, defined by 
Unicode (default).
• GB2312 - Character set of the People's Republic of China, used for simplified Chinese characters. 
• Auto Character Set Failure Option - If the system cannot find a character set from the preferred list 
that can be used to successfully decode the data, the character set selected in Auto Character Set 
Failure Option is used to decode the data and send to the user. If NONE is used, Null data is returned 
as string data.
• NONE
• UTF-8 - A character encoding capable of encoding all possible characters, or code points, defined by 
Unicode (default).
• ISO-8859-1 - Part of the ISO/IEC 8859 series of ASCII-based standard character encodings. It is 
generally intended for Western European languages.
• Shift_JIS - ended for Western European languages.
