linear_security_level Linear Code Type Security Level. Four levels of decode security for
linear code types (e.g., Code 39, Interleaved 2 of 5, Code128 etc).
Higher security levels are selected for decreasing levels of bar code
quality. As security levels increase, the scanner’s aggressiveness
decreases. Select the security level appropriate for your bar code
quality.
Level 1: The following code types must be successfully read twice before
being decoded:
Level 2: All code types must be successfully read twice before being decoded.
Level 3: Code types other than the following must be successfully read twice before
being decoded.
The following codes must be read three times:
Level 4: All code types must be successfully read three times before being decoded.
linear_supp_enabled This option applies to supplemental code types. When enabled, a
bar code is transmitted only when both blocks are successfully
decoded within one laser scan.
code39_xmit_chkdgt Enable to transmit the check digit with the data. Disable to trans-
mit the data without check digit
