5.13.2.10 UPC/EAN Shared Settings
The parameters you set here are a shared across all available UPC and EAN bar codes.
Enable Bookland EAN
Setting this parameter to on allows your scanner to recognize Bookland EAN bar codes.
Supplementals
Supplementals are additionally appended characters (2 or 5).
Double-tapping this parameter displays a list of options. If Ignore is chosen, UPC/EAN is
decoded and the supplemental characters are ignored. If Decode is chosen, UPC/EAN
symbols are decoded with supplementals. Autodiscriminate works in conjunction with the
Supp. Redundancy parameter.
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
Linear Decode applies to code types containing two adjacent blocks (e.g., UPC-A, EAN-8,
EAN-13). When enabled, 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 the omnidirectional
scanner engine only.
