Decode UPC/EAN SupplementalThis option is used to select whether UPC/EAN is decoded with or without 
supplemental characters, or whether the unit will autodiscriminate between the two. 
Supplementals are additionally appended characters, according to specific code format 
conventions (e.g., UPC A+2, UPC E+2, EAN 8+5). If UPC/EAN with supplemental 
characters 2-digit or 5-digit only is selected, UPC/EAN symbols without supplemental 
characters won’t be decoded. If UPC/EAN without supplemental characters is 
selected and the scanner is presented with a UPC/EAN plus supplemental symbol, the 
UPC/EAN will be decoded and the supplemental characters will be ignored. If 
autodiscrimination is chosen, the scanner will, after additional processing to ensure a 
good decode, transmit either. If UPC/EAN with supplemental characters is selected, 
UPC/EAN without supplemental characters is ignored.
