Code 39 (continued)
In the Full ASCII Table in Appendix B, /D represents $ and /E represents %. If you
configure the 5020 for Code 39 full ASCII, the computer decodes the data as $%a
because there are three valid full ASCII character pairs to represent the data.
Other printers encode the data $%a as:
*$%+A*
*$%+A*
The $ and % are valid Code 39 characters in the non-full ASCII character set. However,
the 5020 will not decode this label if it is configured for full ASCII, because the data is
not represented by valid full ASCII character pairs. To decode the label correctly, you
need to configure the 5020 for mixed-full ASCII.
When you configure the 5020 for Code 39 mixed-full ASCII, the 5020 will decode both
of the labels above as $%a.
Mixed-full ASCII interprets any valid full ASCII character pairs that appear in the
label, but does not require that all data be encoded with a valid full ASCII character
pair. If you are uncertain how your labels are encoded, configure the 5020 for mixed-
full ASCII, which decodes all valid Code 39 labels.
If you configure the 5020 for Code 39 full ASCII, you should check for Code 39 mixed-
full ASCII. Mixed-full ASCII does not apply when you configure the computer for non-
full ASCII.
Note: The interpretive text shown under bar code labels does not always accurately
reflect the data that is encoded in the label. The interpretive text represents how the
label should be decoded.
Use this table to help configure your 5020.
