Check Digits Required
This option sets whether 1 or 2 check digits are required with Code 11 bar codes.
Default = Two Check Digits.
Message Length
The message length selection is used to set the valid reading length of the bar
code. If the data length of the scanned bar code doesn’t match the valid reading
length, the scanner will issue an error beep. You may wish to set the same value
for minimum and maximum length to force the scanner to read fixed length bar
code data. This helps reduce the chances of a misread.
