Decoded (Internal) Scanners
Code 93
Security Level
This parameter controls the tolerance for decoding edge-to-edge UPC/EAN bar codes.
Double-tapping on this parameter displays a dialog box in which you can choose a level
from 0 to 3. Lower values have a lower tolerance for misreads, but they also increase the
time it takes to decode the bar code.
Linear Decode
Linear Decode applies to code types containing two adjacent blocks (e.g., UPC-A, EAN-8,
EAN-13). When enabled (set to on), a bar code is transmitted only when both the left and
right blocks are successfully decoded within one laser scan. This option should be enabled
when bar codes are in proximity to each other.
2D UPC Half Block Stitching
Setting this parameter to on enables “UPC Half Block Stitching” for an omnidirectional
engine only.
C.2.11 Code 93
Enabled
Set this parameter to on to enable “Code 93”.
Set Length L1 and Set Length L2
Lengths for “Code 93” can be set for Any Length, Length within a range, One discrete
length or Two discrete lengths. The length of a code refers to the number of characters
(i.e., human readable characters), including check digit(s).
Double-tapping on this parameter displays a dialog box labelled Set Code Lengths where
you can define the code length that will be recognized by your scanner.
Choosing One discrete length allows you to decode only those bar codes of a specified
length. Choosing Two discrete lengths allows you to specify two lengths of bar codes that
may be decoded. Length within a range allows you to decode any bar code with a length that
falls within a specified range (e.g. between 10 and 15 characters). The minimum and
maximum values for the range are 4 and 55, respectively.
