Appendix C: Bar Code Settings

Decoded (Internal) Scanners

Code 93

Supp. Redundancy

With “Autodiscriminate” selected in the Supplementals parameter, Supp. Redundancy

adjusts the number of times a symbol without supplementals is decoded before transmission.

When you double-tap on this parameter, a dialog is displayed in which you can enter a value

between 2 and 20. A value of 5 or above is recommended when Autodiscriminate is selected

and you are decoding a mix of UPC/EAN symbols with and without supplementals.

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 (Model SE2223)

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 (Model SE2223)

Setting this parameter to on enables “UPC Half Block Stitching” for the SE2223 omnidirec-

tional engine only.

C.2.12 Code 93

Enabled

Set this parameter to on to enable “Code 93”, or off to disable it.

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 codes containing a selected

length. Choosing Two discrete lengths allows you to decode only those codes containing two
