### Decode Tool Parameters

##### Symbology Types

Disable unused symbologies to reduce decode times.

Precautions for Correct Use: DotCode cannot be decoded at the same time as other symbologies. If your application requires the decoding of DotCode symbols, enable DotCode only.

##### Match String

Match String allows you to specify the string that must be matched for the Decode Tool to pass. You can enter up to 254 characters.

The Match String function for the Decode Tool allows you to enter a ‘?’ character as a wildcard character. Match String for the Decode Tool does not support special characters.

###### Non-Printable Characters

When a decoded symbol contains non-printable characters, the Match String can accept hexadecimal escape codes. These are of the form \xFF, where FF represents two hexadecimal digits. The "x" and the hex digits are not case sensitive.

To be processed, the escape sequence must be fully formed; otherwise it is treated as if it were not an escape sequence.

For example, to match ABCD<cr>EFG, where <cr> is a carriage return (hex 0D), set Match String to:

ABCD\x0DEFG

Using a serial command, this would be:

SET matchstring1 ABCD\x0DEFG

##### Settings

- GS1 Validation: Choose whether to do GS1 verification.

- Max Symbols: Set the maximum number of symbols and multisymbol separator as needed.
