Appendix D: Bar Codes Settings
Code 39
Transmit Check Digit
If the check digit is to be transmitted with the data, this parameter must to enabled.
Full ASCII
If this parameter is enabled, the characters +, %, and / are used as escape characters. The
combination of an escape character and the next character is converted to an equivalent
ASCII character.
Decode Performance
If this parameter is enabled, one of three decode levels can be chosen in the “Decode Perfor-
mance Level” parameter.
Decode Perf. Level
This parameter provides three levels of decode performance or “aggressiveness” for Code
39 symbols. Increasing the performance level reduces the amount of required bar code ori-
entation – this is useful when scanning very long and/or truncated bar codes. Keep in mind
that increased levels reduce decode security.
When you double-tap on this parameter, a dialog box is displayed in which you can enter a
decode performance level of between 1 and 3.
Length Restriction
The parameters in this sub-menu allow you to define the length of the bar codes that will be
decoded using either the Field Size parameter or the Minimum Size and Maximum Size pa-
rameters (see below). The order of operation to either match the Field Size or determine if
the length falls between the Minimum Size and Maximum Size is as follows:
•
Strip the leading and trailing characters.
• Add the prefix and suffix characters.
• Count the number of characters remaining to either match the field size or determine if
the length falls between the minimum and maximum size.
Field Size
When a value is assigned for this parameter, only bar codes that match the field size exactly
can be transmitted. If a value is assigned to this parameter, a Minimum Size and Maximum
Size value is not required.
