5.28.1.13UPC/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 box 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 (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.
