Full ASCII Conversion
Code 39 has an option that allows the full ASCII character set to be decoded using
the 43 characters of the Code 39 character set.
The full ASCII conversion is done by pairing Code 39 characters. When Code 39
full ASCII conversion is enabled, all valid character pairs will be converted into their
corresponding ASCII characters before being transmitted.
When disabled, all decoded characters will be transmitted without being converted.
*Default is
Full ASCII Conversion Off

Check Character Verification
Check characters are supplemental characters added to a bar code symbol to
allow the verification of decoded data.
If the check character verification is enabled and the check character cannot be
verified, then the bar code symbol will be ignored. If no–read recognition is
enabled, a no–read message will be transmitted.
For more information on Check Characters, refer to page 5–14.

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 greater than the maximum)
will cause a syntax error.
