4-10-2 Advanced Mode
WebLink's Configuration Database Advanced Mode uses two or more unique reader configurations that
are automatically attempted during a read cycle. It allows for multiple reader changes to be made
without user interaction. WebLink is used to configure the database settings and verify that all the
database indexes are working correctly.
The Configuration Database can be used to fine-tune the reader's performance in your application. It
can run multiple decode options in a single read cycle. You can enable Configuration Database by
using the Cycle editor in the Read Cycle Sequence that comprises the left panel in the Setup view of
WebLink's user interface. Configurations are set up individually and saved individually. Configuration
Database is set up in the Setup tab and tested in the Run tab. Virtually all Acquire and Decode settings
can be individualized per database entry. Clicking the gear icon in the Configuration Database editors
shows a view of all database settings. Settings can be based on Window of Interest (WOIs), meaning a
new picture is taken for each decode. Settings can also be based on Regions of Interest (ROIs),
meaning decodes are attempted on a single image.
Important: Quick Photometry should be disabled while using the Configuration Database.
The Configuration Database Advanced Mode is useful in applications where:
• More than one symbol type is present;
• A symbol may require different photometry settings to decode;
• Symbols are presented at different depths;
• Multiple symbols with the same data need to be decoded;
• Multiple symbols need to be read in a specific order.
Overview of Setup Process
Use the Cycle editor in the left panel in the Setup view to enable Configuration Database.
Use Weblink to configure each of the database indexes by selecting them in the Setup view.
 Tips
• Database indexes are not cycled in Setup mode. Switch to Run mode for read cycle testing.
• Set the "Look for n codes" value to match the number of barcodes you need to decode.
• If decoding multiple barcodes in the same image, make the following changes in Advanced Set-
tings > Configuration Database:
• Image Process Looping: Set to Enabled
• Image Dimensions: Set to Region of Interest
• Save each index configuration by clicking on the Save icon when done.
• Remember that the Index number is only output in Run mode if it is Enabled.
• Save settings to the reader's flash memory when all the indexes in the Configuration Database
have been defined for the application.
