• Linear Decode - This option applies to code types containing two adjacent blocks, for example, UPC-A, 
EAN-8, EAN-13. Enable this parameter to transmit a bar code only when both the left and right blocks are 
successfully decoded within one laser scan. Enable this option when bar codes are in proximity to each 
other (default - enabled).
• 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 values: 
Supplementals Auto, Supplementals Smart, Supplementals 378-379, Supplementals 978-979, 
Supplementals 977 or Supplementals 414-419-434-439 (2 to 20, default 10).
• 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 -
