Symbologies 12 - 61

UPC symbols can be “linked” with a 2D symbol during transmission as if they were one symbol. Three options are 
offered for these symbols:

If UPC Never Linked is selected, UPC bar codes are transmitted regardless of whether a 2D symbol is 
detected.

If UPC Always Linked is selected, UPC bar codes are only transmitted when the 2D portion is detected.

If Autodiscriminate UPC Composites is selected, the scanner determines if there is a 2D portion, then 
transmits the UPC portion only.
