DataWedge 4 - 15
• Security Level - The scanner offers four levels of decode security for Code 128 bar codes. Select increasing
levels of security for decreasing levels of bar code quality. There is an inverse relationship between security
and scanner aggressiveness, so choose only that level of security necessary for any given application.
• Security Level 0 - This setting allows the scanner to operate in its most aggressive state, while providing
sufficient security in decoding most “in-spec” bar codes.
• Security Level 1 - This setting eliminates most misdecodes (default).
• Security Level 2 - Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3 - If Security Level 2 is selected and misdecodes still occur, select this security level. Be
advised, selecting this option is an extreme measure against mis-decoding severely out of spec bar
codes. Selecting this level of security significantly impairs the decoding ability of the scanner. If this level
of security is needed, try to improve the quality of the bar codes.
Code39
• Code39 Reduced Quiet Zone - Enables decoding of margin-less Code 39 bar codes.
• Convert Code39 To Code32 - Code 32 is a variant of Code 39 used by the Italian pharmaceutical industry.
Scan the appropriate bar code below to enable or disable converting Code 39 to Code 32 (default - disabled).
• Full ASCII- Code 39 Full ASCII is a variant of Code 39 that pairs characters to encode the full ASCII
character set. To enable or disable Code 39 Full ASCII (default - disabled),
• Length1 - Use to set decode lengths (default - 0). See Decode Lengths on page 4-19 for more information.
• Length2 - Use to set decode lengths 4 (default - 55). See Decode Lengths on page 4-19 for more
information.
• Redundancy - Sets the reader to read the bar code twice before accepting data. A check in the checkbox
indicates that redundancy is enabled (default - disabled).
• Report Check Digit - Transmit Code 39 data with or without the check digit. A check in the checkbox
indicates to send Code 39 data with check digit (default - disabled).
• Report Code32 Prefix - Scan the appropriate bar code to enable or disable adding the prefix character “A”
to all Code 32 bar codes (default - disabled).
• Security Level - Options: Security level 0, Security Level 1, Security Level 2 and Security Level 3
(default - Security level 1).
• Security Level 0 - This setting allows the scanner to operate in its most aggressive state, while providing
sufficient security in decoding most “in-spec” bar codes.
• Security Level 1 - This setting eliminates most misdecodes (default).
• Security Level 2 - Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3 - If Security Level 2 is selected and misdecodes still occur, select this security level. Be
advised, selecting this option is an extreme measure against mis-decoding severely out of spec bar
codes. Selecting this level of security significantly impairs the decoding ability of the scanner. If this level
of security is needed, try to improve the quality of the bar codes.
• Verify Check Digit - Enable this feature to check the integrity of all Code 39 symbols to verify that the data
complies with a specified check digit algorithm. The digital scanner decodes only those Code 39 symbols
that include a modulo 43 check digit. Enable this feature only if the Code 39 symbols contain a modulo 43
check digit (default - disabled).
Code93
• Length1 - Use to set decode lengths (default - 0). See Decode Lengths on page 4-19 for more information.
• Length2 - Use to set decode lengths (default - 55). See Decode Lengths on page 4-19 for more information.
• Redundancy - Sets the reader to read the bar code twice before accepting data. A check in the checkbox
indicates that redundancy is enabled (default - disabled).
