Minimum and Maximum Lengths
The length of a decoded bar code may be checked to see if it matches a set of
predefined (configurable) limits. If the length of the bar code is within these limits, it
is accepted as valid. If the length is outside the limits, a no–read condition exists.
Default minimum length is 1, default maximum length is 32
The length to be checked includes any check characters but does not include
start and stop characters. If you want to check for a specific length, the
minimum and the maximum should be set to the same number. Setting the
maximum less than the minimum (or the minimum more than the maximum) will
cause a syntax error.

Selecting the Number of Code 11 Check Characters
Check character verification of Code 11 is mandatory. The number of check
characters may be one or two. If the length of the data is less than or equal to
ten, one check character is normally used. If more than ten data characters are
present, two check characters are used.
If the check character is incorrect, then the bar code symbol will be ignored, or if
no–read recognition is enabled, a no–read message will be transmitted.
For more information on check characters, refer to page 5–14.

1 Check Character .
