WebLink's Configuration Database is a system that uses two or more unique camera configurations that are automatically attempted during a read cycle. It allows for multiple camera changes to be made without interaction from the user. 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 and define the number of configurations in Advanced Settings. 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 shows a view of all database settings. Settings can be based on Windows 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: Auto Photometry should be disabled while using the Configuration Database.
The Configuration Database 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.
Use WebLink to define the number of active database indexes, located in the Advanced Settings.
Use Weblink to configure each of the database indexes by selecting them in the Setup view.
You can use Assisted Setup, Create a New Setup, and Load a Setup, along with Advanced Settings, to manipulate reader settings.
Note: Assisted Setup and Create a New Setup will both default the reader.
Note: Advanced Settings, while in the Start and Run views, allows you to manipulate all reader settings except the individual Configuration Database index settings. The settings that are shared between the global and Configuration Database index are ignored by the reader. While in the Setup view, the reader pauses the Configuration Database and any changes to the shared settings can be saved into any of the available Configuration Database indexes.
While in the Start and Run views, you can see which database decoded the symbol:
The Setup view displays a Configuration Database section that allows you to add and remove active indexes to and from the database. It also allows you to select specific indexes to modify.
Once you change settings, you can then save to any index by clicking the Save button available for each index.
Note: The Save button icons are blue for each index by default. In the example below, settings were saved to the 6th index. The Save button will continue to appear green until another setting is sent to the reader.
You can also access the extra Configuration Database in a popup dialog by clicking the Extra Settings gear icon. This provides a read-only view of the Configuration Database showing all available settings. It also includes the Advanced Settings that are available in the Advanced Settings dialog.
When you click WOI, the Configuration Database uses the Top, Left, Width, and Height values as Window of Interest values. When you click ROI, the Configuration Database will use Top, Left, Width, and Height values as Region of Interest values.
The Advanced Settings dialog shows the extra configuration settings not present in the Configuration Database in the left panel of the WebLink user interface. This is where you would enable the Configuration Database if it isn’t already enabled.
If you enable Sort Database, a warning will appear in the Configuration Database section of the left panel.
Note: The primary way to enable the Configuration Database in the WebLink user interface is to open the Advanced Settings dialog and increase the number of Active Indexes. An alternate option is to use the Terminal and set the index count using the <K252> command. If there are no Active Indexes, the Configuration Database view is hidden. Once they are available, either via Advanced Settings or Terminal, the Configuration Database view will appear. If you remove the last index, a warning dialog will appear:
The user interface shows which settings are affected by the Configuration Database using dark blue highlighting around the Acquire and Decode steps.
If you are in Rapid Capture Mode and have fewer captures than the Configuration Database has Active Indexes, the extra Active Indexes will not be triggered. A warning icon will appear if this occurs.
If you remove an index that is selected (4), WebLink will select and load index 1.
Note: Learn (Train) and Optimize functionality are not available with Configuration Database.
