When enabled, a UPC/EAN barcode is only decoded and transmitted when both the left and right blocks are successfully decoded within one image.
When disabled, the left and right blocks can be decoded in different images and transmitted together.
This parameter applies to code types containing two adjacent blocks (such as UPC-A, EAN-8, and EAN-13).
Enabled - Requires both the left and right blocks to be decoded successfully in one image.
Disabled - The left and right blocks can be decoded in different images.
This is recommended when barcodes are in proximity to each other.
