UPC/EAN Security Level
Use this parameter to determine the security level appropriate for UPC/EAN bar code quality. There is an inverse relationship between security and scanner aggressiveness, so be sure to choose only that level of security necessary for any given application.
There are four decode security levels. Higher security levels are selected for decreasing levels of bar code quality. As security levels increase, the scanners aggressiveness decreases.
Level 0 | The default setting. |
| Allows the scanner to operate in its most aggressive state, while providing sufficient security in |
| decoding |
|
|
Level 1 | Misdecode 1,2,7,8 |
| As bar code quality levels diminish, certain characters become prone to misdecodes before others |
| (i.e., 1, 2, 7, 8). |
| Select this level upon misdecodes of poorly printed labels that are limited to 1, 2, 7 and 8. |
|
|
Level 2 | Misdecodes not 1,2,7,8 |
| Select this security level upon experiencing misdecodes of poorly printed bar codes and the |
| misdecodes are not limited to characters 1,2,7 and 8. |
|
|
Level 3 | Select this security level if you have tried security level 2 and are still experiencing misdecodes. |
| Using this level is an extreme measure against misdecoding severely out of spec bar codes. |
| This level significantly impairs the decoding ability of the scanner. |
| If this level of security is necessary, you should try to improve the quality of your bar codes. |
