Security Level
The decoder offers four levels of decode security for delta barcodes, which include
UPC/EAN and Code 93. Select increasing levels of security for decreasing levels of
barcode quality. There is an inverse relationship between security and decoder
aggressiveness, so choose only that level of security necessary for any given
application.
Security Level 0:
This setting allows the decoder to operate in its most
aggressive state, while providing sufficient security in decoding most “in-spec”
barcodes.
Security Level 1:
This default setting eliminates most misdecodes.
Security Level 2:
Select this option if Security level 1 fails to eliminate
misdecodes.
