this, the I 2 of 5 code type must be enabled, one length must be
set to 14, and the code must have a leading zero and a valid
EAN-13 check digit.
cvtC39_2_C32 Convert Code39 to Code32. Code 39 must be enabled in order
for this parameter to function.
C32Prefix Code32 Prefix. Enable this parameter to add the prefix charac-
ter “A” to all Code 32 bar codes. Convert Code 39 to Code 32
must be enabled for this parameter to function.
EnableC128Perf Enable Code128 Performance. This option offers three levels of
decode performance or “aggressiveness” for Code 128 symbols.
Increasing the performance level reduces the amount of required
bar code orientation, which is useful if you are scanning very
long and/or truncated bar codes. Increased levels reduce decode
security. If you enable this option, you may select a Decode Per-
formance level to suit your performance needs.
C128PerfLvl Code128 Decode Performance Level. Valid from Level 1 to
Level 3.
EnableC39Perf Enable Code39 Decode Performance. This option offers three
levels of decode performance or “aggressiveness” for Code 39
symbols. Increasing the performance level reduces the amount of
required bar code orientation, which is useful if you are scanning
very long and/or truncated bar codes. Increased levels reduce
decode security. If you enable this option, you may select a
Decode Performance level to suit your performance needs. This
option only works with Code 39 One Discrete Length.
C39PerfLvl Code39 Decode Performance Level. Valid from Level 1 to Level
3.
