• Security Level - The scanner offers four levels of decode security for UPC/EAN barcodes. Select higher
security levels for lower quality barcodes. There is an inverse relationship between security and decode
speed, so be sure to choose only that level of security necessary for the application.
• Level 0 - This default setting allows the scanner to operate fastest, while providing sufficient security in
decoding “in-spec” UPC/EAN barcodes.
• Level 1 - As barcode quality levels diminish, certain characters become prone to misdecodes before
others (i.e., 1, 2, 7, 8). If the scanner is misdecoding poorly printed barcodes, and the misdecodes are
limited to these characters, select this security level. (default).
• Level 2 - If the scanner is misdecoding poorly printed barcodes, and the misdecodes are not limited to
characters 1, 2, 7, and 8, select this security level.
• Level 3 - If the scanner is still misdecoding, select this security level. Be advised, selecting this option is
an extreme measure against misdecoding severely out of spec barcodes. Selecting this level of security
can significantly impair the decoding ability of the scanner. If this level of security is necessary, try to
improve the quality of the barcodes.
• Supplemental2 - Enables or disables this option. A check in the checkbox indicates that the option is
enabled.
• Supplemental5 - Enables or disables this option. A check in the checkbox indicates that the option is
enabled.
• Supplemental Mode
• No Supplementals - the scanner is presented with a UPC/EAN plus supplemental symbol, the scanner
decodes UPC/EAN and ignores the supplemental characters (default).
• Supplemental Always - the scanner only decodes UPC/EAN symbols with supplemental characters,
and ignores symbols without supplementals.
• Supplements Auto - the scanner decodes UPC/EAN symbols with supplemental characters
immediately. If the symbol does not have a supplemental, the scanner must decode the barcode the
number of times set via UPC/EAN Supplemental Redundancy before transmitting its data to confirm that
there is no supplemental.
• Supplemental Smart - Enables smart supplementals. In this mode the decoder returns the decoded
value of the main block right away if it does not belong to one of the following supplemental types: 378,
379, 977, 978, 979, 414, 419, 434 or 439. If the barcode starts with one of the prefixes it searches the
image more aggressively for a supplemental. Tries to scan the supplemental if it is present. If the
supplemental scanning failed, then the main barcode is returned
.
• Supplemental 378-379 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with
378 or 379. Disables reading of supplementals for any other UPC/EAN barcode not starting with 378 or
379. Tries to scan the supplemental if it is present. If the supplemental scanning failed, then the main
barcode is returned.
• Supplemental 978-979 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with
978 or 979. Disables reading of supplementals for another UPC/EAN barcode not starting with 978 or
979. Tries to scan the supplemental if it is present. If the supplemental scanning failed, then the main
barcode is returned.
• Supplemental 414-419-434-439 - Enables (auto-discriminate) supplemental for UPC/EAN codes
starting with 414, 419, 434 or 439. Disables reading of supplementals for another UPC/EAN barcode 4 -
16 not starting with 414, 419, 434 or 439. Tries to scan the supplemental if it is present. If the
supplemental scanning failed, then the main barcode is returned.
• Supplemental 977 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 977.
Disables reading of supplementals for another UPC/EAN barcode not starting with 977. Tries to scan
the supplemental if it is present. If the supplemental scanning failed, then the main barcode is returned.
