UPC/EAN Security Level
Parameter # 0x4D
The SE 824 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
scanner’s aggressiveness, so choose only that level of security necessary for the
application.
UPC/EAN Security Level 0
This default setting allows the scanner to operate in its most aggressive state, while
providing sufficient security in decoding most “in-spec” UPC/EAN bar codes.

(0x00)
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.
