How can I use the Tune button?

Click the Tune button on the Basic tab to automatically find the best settings for your reading. The drop-down window (click the right-most side of the button to open it) reveals the Optimize Focus, Optimize Brightness, Symbology Assistant, Trigger Types, Train Code, Advanced Trigger Settings, and miscellaneous tune features.

NOTE: The minimum ROI size required for Tune to work is 144x144 pixels.

The options at the top of the drop-down window are described in separate questions below.

Click Optimize Brightness to set the recommended brightness for your device automatically (only available if Manual Exposure is set below), or click the link next to the button to navigate to the Application Details application step where you can set light intensity manually and find advanced settings.

Select Automatic Exposure option to have the reader automatically determine the best exposure settings in the image. The Gain Factor slider (below the image view area) indicates the target's pixel brightness.

Select Manual Exposure option for manual exposure and then drag the Maximum Exposure slider to the left or to the right to specify a precise setting for camera exposure. Alternatively, you can use the slider below the image view area. The Maximum Gain Factor setting is used to set the target's maximum pixel brightness.

Click Optimize Focus to set the recommended focus for your device automatically, or click the link next to the button to navigate to the appropriate pane under Application Details where you can set the camera focus manually and find advanced settings. You can optimize focus also by using the slider below the image view field (with the focus icon). Note that it only appears when using liquid lens.

Click Train Code to train or (in case a code is already trained) untrain codes, or click the link next to the button to navigate to advanced code training settings on the Code Details application step.

The Symbology Assistant is a wizard that walks you through the setup of reading and decoding the appropriate or desired symbologies. You can also manually tweak symbology settings by clicking on the link next to the assistant, which will navigate to the Code Details application step.

Configure the reader with any of the following Trigger Types:

• Single triggering acquires a single image and attempts to decode any symbol it might contain. This trigger mode supports a read timeout.

• Presentation triggering continuously scans for a symbol and decodes it each time one is detected.

• Manual triggering acquires images as long as the trigger signal remains active, and stops when a symbol is found and decoded or the trigger signal ends.

• Burst triggering acquires a set number of images and decodes the first symbol it detects within the group. You can configure the number of images within each burst as well as the interval between each image acquisition. This trigger mode supports a read timeout.

• Self triggering is similar to presentation triggering in that the reader continuously scans for a symbol and decodes it each time one is detected.

• Continuous triggering acquires images as long as the trigger signal remains active, where the reader acquires images at a specific interval and attempts to scan any symbols each successive image contains.

Note: Not all trigger types are available for all devices! Check the corresponding Reference Manuals for more information on the available trigger types of your device model.

Clicking the Advanced trigger settings link at the bottom navigates you to the Application Details step where you can have further settings.

On the Advanced tab, you can set the values in a table view.
