Overview
The UpcEanSecurityLevel Decoder Setting is used to set the upcEanSecurityLevel which describes the UPC/EAN security level.
Syntax
| upcEanSecurityLevel (Decoder Setting) <META> Syntax |
|---|
<META HTTP-Equiv="scanner" content="upcEanSecurityLevel:[parameter]"> |
| upcEanSecurityLevel JavaScript Object Syntax: |
|---|
| By default the JavaScript Object 'scanner' will exist on the current page and can be used to interact directly with the upcEanSecurityLevel. |
|
To Set upcEanSecurityLevel parameters via JavaScript use the following syntax: scanner.Parameter = Value;
e.g. scanner.upcEanSecurityLevel = Value; |
Parameters
Items listed in this section indicate parameters, or attributes which can be set.
| Name | Possible Values | Description | Default Value |
|---|---|---|---|
| upcEanSecurityLevel:[Value] | 0 - 3 inclusive | 0: This setting allows the scanner to operate in its most aggressive state, while providing sufficient security in decoding most 'in-spec' barcodes. 1: This setting eliminates most mis-decodes. 2: Select this option if security level 1 fails to eliminate mis-decodes. 3: Select this option if security level 1 and 2 fail to eliminate mis-decodes. Be advised that selecting level 3 is an extreme measure against mis-decoding and will significantly impair the decoding ability of the scanner. | Device specific |

HTML/JavaScript Examples
The following example sets the upcEanSecurityLevel to check ambiguous characters:
<META HTTP-Equiv="scanner" Content="allDecoders:enabled">
<META HTTP-Equiv="scanner" Content="upcEanSecurityLevel:ambiguous">
<META HTTP-Equiv="scanner" Content="enabled">
Above example can also be written as shown below:
<META HTTP-Equiv="scanner" Content="allDecoders:enabled;upcEanSecurityLevel:ambiguous;enabled">
or
<META HTTP-Equiv="scanner-allDecoders" Content="enabled">
<META HTTP-Equiv="scanner-upcEanSecurityLevel" Content="ambiguous">
<META HTTP-Equiv="scanner-enabled" Content="SCN1">
