The Check Digit Present parameter permits you to determine if the bar code must contain a correct check digit to be identified as valid.

Allow 1- or 2-Character Tags

The Allow One- or Two-Character Tags parameter selects whether or not to permit the scanner to read a one- or two-character Code 39 label. If your application does not require that the scanner read a one- or two-character Code 39 label, scan the Hex 0 tag to disable this option. If your application requires this capability, scan the Hex 1 tag to enable it. The default is to disable reading a one- or two-character Code 39 label.
