This window is very similar to the Barcode Reading Settings window. The only panel missing is the trigger panel. This window allows you to configure barcode splitting at input time. The default behavior is similar to PatchCode splitting where the pages that contain the desired barcodes are deleted. This kind of splitting have several uses but it is not very flexible.
The recommended technique for splitting documents using barcode is by using barcode triggers. A video tutorial on barcode triggering can be found here.
Barcode Types
On this area you should select all the barcodes that are present on your documents, otherwise ChronoScan will recognize them but not read them.
The more barcode types you have selected the longer each document will take to scan.
