Advanced FIS Tools

The Advanced tab provides access to additional Fixed Industrial Scanning tool settings.

All Advanced detection methods apply to both 1D and 2D barcodes.

Advanced Fixed Industrial Scanning Tool Settings
Setting	Description
Decode Strategy	Changes the variables to alter the balance of speed and performance. Fast – This strategy is designed to be fast but may not find a barcode if it is hard to find. Moderate - This strategy is helpful for most use cases with a moderate increase in analysis times. Exhaustive – This strategy does an exhaustive search to identify hard to find barcodes. This method can sometimes lengthen analysis time significantly.
Detection Method	Determine the preferred method for detecting the data: Uniform—uses a splatter pattern to analyze the whole image uniformly. This is helpful for 1D and 2D barcodes with a lot of noise. If you are looking for a random pattern, favor the center of the image slightly. Quiet Zone - specialized to find 2D barcodes fast and helpful when over 8 pixels of buffer zone around the barcode is expected. This setting may not be helpful for use cases when the buffer area is less than 4 pixels or 1D barcodes. Finder Pattern - uses a contrast map that finds patterns with little or no noise. This method is applicable to 1D and 2D barcodes.
Allow Rectangular Codes	Allows the reading of 2D rectangular barcodes in addition to square 2D barcodes.
Expected Module Size (Pixels)	Define the range (pixels) you expect a module to be in given barcodes to help increase read performance. A module is the smallest divisible unit of a barcode; for 1D, typically the width of a single thin line; for 2D, the pixel size. This setting serves as a general guidance to increase performance, but is not a strict threshold.
