Setting Code Specific Options - Options for specific codes may be configured affecting:

*

Enabling and disabling code variants and translations.

*

Data verification such as by mean of a check digit calculation. A check digit has a value that can be calculated from

the other data characters and is usually the last data character in a bar code.

*

Pre-editing of the data string such as removing the check digit and/or ST/SP characters.

The more common options are described here.
Check CD - Enables the check digit calculation. If the calculated check digit does not correspond to the check digit in the bar
code, then the bar code is ignored. The use of a check digit greatly improves the security of a bar code.
Do Not Check CD - Disables the check digit calculation. This option is required when the bar codes do not contain a check digit
or contain an invalid check digit.
Transmit CD - Enables the transmission of the check digit together with the data characters. If the check digit calculation is
disabled, the reader cannot differentiate anymore between a (valid) check digit and a data character. It will therefore transmit all
data characters of the label, including what could constitute a check digit.
Do Not Transmit CD - Disables the transmission of the check digit. If the check digit calculation is disabled, the reader cannot
differentiate between a (valid) check digit and a data character. It will therefore transmit all data characters of the able, excluding
the character that could constitute the check digit for the type of bar code.
Transmit ST/SP - Enables the transmission of the start and stop characters of a bar code.
Do Not Transmit ST/SP - Disables the transmission of the start and stop characters of a bar code.
