Datacode

Configure Datacode settings such as No Read String, Module Size, or Search Strategy. This tool is helpful for reading 2D barcodes that are difficult to decode and 1D codes with selected symbology.

General Datacode Decode Settings

General Datacode decode settings include defining timeout, symbologies, no read string, module size, contrast threshold, polarity, and string match.

General Datacode Decode Settings
Setting	Description
Timeout	Set a time limit to stop the execution of the inspection tool, resulting in a failure.
Symbologies	Select Data Matrix, QR, or Linear Barcodes. Linear Barcodes include: Code 39 Code 128 Interleaved 2 of 5 Code 93 EAN-13 EAN-8 UPC-A UPC-E
No Read String	Determine the string that is shown when there are no decoded values.
Module Size	The minimum and maximum range for module size.
Contrast Threshold	The threshold used for Datacode.By default, this is set to 10.
Polarity	Select a polarity for the decode: Any Bright Dark Mixed
Barcode String Match	Define a string that must be exact or contained within the barcode or datacode output for the tool to pass: Disabled - no match string. Exact String - string must match the exact string provided. String Contains - code must contain the match string. RegEx - enable to input complex match string conditions.

Advanced Datacode Decode Settings

Advanced Datacode decode settings include defining a detection strategy, decoding strategy, module size, detection method, finder tradeoff, contrast threshold, line count, distortion, gap size, code slant, super-resolution, perspective level, edge tracker, mirrored codes, broken patterns, rectangular codes, and codes with broken corners.

Advanced Datacode Decode Settings
Setting	Description
Detection Strategy	Specify the step of image downsampling used for finding codes at different scales: Super Fast Fast Precise Strict Extended
Decoding Strategy	Specify the precision of outline detection: Super Fast Fast Precise Strict Extended
Detection Method	Specify how code candidates are located: Finder Edges Quiet Zone
Finder Tradeoff	Decide how to optimize parameters for weak or jagged edges: Extra Sensitive Sensitive Balanced Robust Extra Robust
Line Count	Limit the number of Data Matrix modules in a row and column.
Allow Distortion	Specify a distortion level: None Low Medium High
Expected Gap Size	Specify the distance between neighboring modules. Zero Small Medium Large
Maximum Code Slant	Specify the maximum deviation from the right angle in the corner of the Finder Pattern.
Use Super Resolution	Specify the image up-scaling method for low-resolution codes depending on the minimum module size: Auto Yes No
Perspective Level	Specify a perspective distortion of the code grid: None Low High
Edge Tracker	Specify how strongly to preserve the continuity of an edge: Very Weak Weak Medium Strong Very Strong
Barcodes	The following parameters are applied only to linear barcodes: Barcode Length: Any Discrete - select a specific number as the barcode length. Range - select a range of numbers as the barcode length.
