Decode Filter Use these settings to modify or reject data strings.
• Decode filter script
The Decode Filter Script is used to configure a filter for
decode results during scanning. For example, a filter could
be used to reject barcodes that don't begin with certain
characters, remove leading characters (like “00”) from the
beginning of a barcode, or only scan barcodes that begin
with certain characters.
• Decode filter timeout (ms)
The decode filter timeout option can be used to disable the
logic inside the filter script after a given amount of time.
• Debug level
Set the filter information level. The default level is 0, no
information. Higher levels emit more information. Level 4
emits the most information.
