Code 39 (continued)
According to the full ASCII table in Appendix A, $ is represented by /D and %
is represented by /E. This data is decoded as $%a if the JANUS 2050 is
configured for full ASCII, because all the data is represented by valid full
ASCII characters pairs.
Other printers encode the data $%a as:
*$%+A*
*$%+A*
The $ and % are valid Code 39 characters in the non-full ASCII character set.
However, this label will NOT be decoded by the JANUS 2050 if it is configured
for full ASCII, because the data is NOT represented by valid full ASCII
character pairs. To decode the label correctly, configure the JANUS 2050 for
mixed-full ASCII.
When configured for mixed-full ASCII, the JANUS 2050 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
JANUS 2050 for mixed-full ASCII, which decodes all valid Code 39 labels.
If you are configuring the JANUS 2050 for Code 39 full ASCII, you should
check for mixed-full ASCII. Mixed-full ASCII does not apply when you are
configuring the JANUS 2050 for non-full ASCII.
Note: The interpretive text found 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.
The following table can aid you in configuring your JANUS 2050.
JANUS 2050 Bar Code Decode
Non-full ASCII $%+A
/D/E+A $%+A
/D/E+A
Full ASCII $%+A
/D/E+A No decode
$%a
Mixed-full ASCII $%+A
/D/E+A $%a

Default: Enable full ASCII with no check digit (111)
