G-11-4 Fixed Symbol Length Status (Codabar)
Definition:
When disabled, the reader will accept any Codabar symbol provided it
doesn’t exceed the system’s maximum capabilities.
When enabled, the reader will reject any Codabar symbol that doesn’t
match the fixed length.

G-11-6 Check Character Type (Codabar)
Definition:
When disabled, the reader will not perform any character checking calculations
on decoded Codabar symbols.
When set to
Mod 16
, the reader will perform a modulus 16 check character
calculation on the symbol. If the symbol does not pass this calculation, it
will not be decoded.
When set to
NW7
, The reader will perform an NW7 modulus 11 check character
calculation on the symbol. If the symbol does not pass this calculation, it will not
be decoded.
When set to
Both
, the reader will perform both the Mod 16 and NW7 modulus
11 check character calculations on the symbol. If the symbol does not pass
either calculation, it will not be decoded.

G-11-7 Check Character Output (Codabar)
Definition:
When this field is disabled and a check character calculation is enabled,
the reader will strip the verified check character from the symbol data out-
put. This condition must be accounted for if a fixed length is also being
used.
When enabled, the reader will output the check character as part of the
symbol data. This condition must be accounted for if a fixed length is also
being used.
