Symbology - Specific Security Levels
Linear Code Type Security Level
In most environments and applications the default setting provides an adequate level of
security. However, some environments or applications may require an increased reading of
security such as poorly printed bar codes, use of weak symbologies, or mission critical
applications. As the security level increases, the scanner decode speed may decrease.
Select the security level appropriate for your environment or application.
Note: These security levels do not apply to UPC/EAN and RSS.
Linear Security Level 1
Level 1 affects only Codabar, MSI, D2 of 5 and I 2 of 5. The codes listed in Table 11-3 below
will be successfully read twice before reporting a good decode.
