Overview
The Code128securityLevel Decoder Setting is used to set the code128securityLevel which describes the Code 128 security level.
Syntax
| Code128securityLevel (Decoder Setting) <META> Syntax |
|---|
<META HTTP-Equiv="scanner" content="code128securityLevel:[parameter]"> |
| Code128securityLevel JavaScript Object Syntax: |
|---|
| By default the JavaScript Object 'scanner' will exist on the current page and can be used to interact directly with the Code128securityLevel. |
|
To Set Code128securityLevel parameters via JavaScript use the following syntax: scanner.Parameter = Value;
e.g. scanner.code128securityLevel = Value; |
Parameters
Items listed in this section indicate parameters, or attributes which can be set.
| Name | Possible Values | Description | Default Value |
|---|---|---|---|
| code128securityLevel:[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 code128securityLevel to level 2:
<META HTTP-Equiv="scanner" Content="allDecoders:enabled">
<META HTTP-Equiv="scanner" Content="code128securityLevel:2">
<META HTTP-Equiv="scanner" Content="enabled">
Above example can also be written as shown below:
<META HTTP-Equiv="scanner" Content="allDecoders:enabled;code128securityLevel:2;enabled">
or
<META HTTP-Equiv="scanner-allDecoders" Content="enabled">
<META HTTP-Equiv="scanner-code128securityLevel" Content="2">
<META HTTP-Equiv="scanner-enabled" Content="SCN1">
