5.11.3.11 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 (

SE2223 only)

“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.
