UPC/EAN Security Level

Parameter # 0x4D
The SE955 offers four levels of decode security for UPC/EAN bar codes. Increasing levels of security are provided for decreasing levels
of bar code quality. Select higher levels of security for decreasing levels of bar code quality. Increasing security decreases the scan
engine's aggressiveness, so choose only that level of security necessary for the application.
UPC/EAN Security Level 0
This default setting allows the scan engine to operate in its most aggressive state, while providing sufficient security in decoding
most "in-spec" UPC/EAN bar codes.
UPC/EAN Security Level 1
As bar code quality levels diminish, certain characters become prone to mis-decodes before others (i.e., 1, 2, 7, 8). If mis-decodes of
poorly printed bar codes occur, and the mis-decodes are limited to these characters, select this security level.
UPC/EAN Security Level 2
If mis-decodes of poorly printed bar codes occur, and the mis-decodes are not limited to characters 1, 2, 7, and 8, select this security
level.
UPC/EAN Security Level 3
If misdecodes still occur after selecting Security Level 2, select this security level. Be advised, selecting this option is an extreme
measure against mis-decoding severely out of spec bar codes. Selection of this level of security significantly impairs the decoding
ability of the scan engine. If this level of security is necessary, try to improve the quality of the bar codes.
