UPC EAN Params
Allows the configuration of the parameters that apply to more than one UPC or EAN decoder.
• Security Level - The scanner offers four levels of decode security for UPC/EAN bar codes. Select higher security
levels for lower quality bar codes. 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 bar codes (default).
– Level 1 - As bar code quality levels diminish, certain characters become prone to misdecodes before others
(i.e., 1, 2, 7, 8). If the scanner is misdecoding poorly printed bar codes, and the misdecodes are limited to
these characters, select this security level.
– Level 2 - If the scanner is misdecoding poorly printed bar codes, 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 bar codes. 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 bar codes.
• 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 bar code 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 bar code 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 bar code 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 bar code not starting with 378 or 379. Tries to
scan the supplemental if it is present. If the supplemental scanning failed, then the main bar code 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 bar code not starting with 978 or 979. Tries to
scan the supplemental if it is present. If the supplemental scanning failed, then the main bar code 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 bar code 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 bar code 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 bar code is returned.
• Retry Count - Retry count for auto-discriminating for supplementals. Possible values are 2 to 20 inclusive.
Note that this flag is only considered if Supplemental Mode - UPC EAN is set to one of the following
