Decode UPC/EAN/JAN Supplementals
Supplementals are bar codes appended according to specific format conventions (e.g., UPC A+2, UPC E+2, EAN 13+2). Six options are
available.
• If Decode UPC/EAN Only With Supplementals is selected, UPC/EAN symbols without supplementals are not decoded.
• If Ignore Supplementals is selected, and the scanner is presented with a UPC/EAN with a supplemental, the UPC/
EAN is decoded and the supplemental bar code is ignored.
• An Autodiscriminate Option is also available. If this option is selected, choose an appropriate supplemental redundancy
value (refer to UPC/EAN/JAN Supplemental Redundancy on page 12-14 ). A value of 14 or more is recommended.
• Enable 378/379 Supplemental Mode to enable only EAN13 bar codes starting with a ‘378’ or ‘379’ prefix to be delayed
by the supplemental search process. All other UPC/EAN bar codes are exempted from the search and are reported instantly
upon their decode.
• Select Enable 978 Supplemental Mode to enable only EAN13 bar codes starting with a ‘978’ prefix to be delayed by the
supplemental search process. All other UPC/EAN bar codes are exempted from the search and are reported instantly upon
their decode.
• Select Enable Smart Supplemental Mode to enable only EAN13 bar codes starting with a ‘378,’ ‘379,’ or ‘978’ prefix to
be delayed by the supplemental search process. All other UPC/EAN bar codes are exempted from the search and are
reported instantly upon their decode.
To minimize the risk of invalid data transmission, select either to decode or ignore supplemental characters.
