Redundancy Level
Security Level
136
Sets how many successful readings should be done before certain
barcodes are decoded. Levels 1 to 4 available; default setting is Level
1. The readings needed for each level are as follows:
Level 1 The following barcodes must be successfully read
twice before being decoded:
Barcode Types
Codabar
MSI
Industrial 25 (Discrete 25)
Interleaved 25
Level 2 All barcodes must be successfully read twice before
being decoded.
Level 3 All barcodes must be successfully read twice before
being decoded, except for the following which must be
read three times:
Barcode Types
Codabar
MSI
Industrial 25 (Discrete 25)
Interleaved 25
Level 4 All barcodes must be successfully read three times
before being decoded.
Selects the security level to ensure decoding accuracy considering the
printed quality of certain barcodes. Default setting is Level 0. The
higher the level, the greater the security. Options are:
Level Description
0 With this default, the scan engine is aggressive enough to
decode most "in-spec" barcodes.
1 Select this level if misdecodes have occurred. It fixes
most misdecodes.
2 Select this level if Level
misdecodes.
3 Select this level if Security Level 2 should fail to prevent
misdecodes. However, as this level actually impairs the
decoding ability of the decoder, a safer solution would be
to improve the quality of the bar codes to read.
