When Check Character is set to Validate, but Don’t Transmit, the unit will only read Codabar bar codes printed with a 
check character, but will not transmit the check character with the scanned data.
Codabar Concatenation
Codabar supports symbol concatenation.  When you enable concatenation, the scanner looks for a Codabar symbol having 
a “D” start character, adjacent to a symbol having a “D” stop character.  In this case the two messages are concatenated 
into one with the “D” characters omitted. 
Select Require to prevent the scanner from decoding a single “D” Codabar symbol without its companion.  This selection 
has no effect on Codabar symbols without Stop/Start D characters.
