This setting can be changed in the Datawedge app on the ZEBRA scanner.
Open the Datawedge app and select the “Warehouse Insight” profile. Find the scanner settings in this list, and you should be able to change it from the camera to the barcode scanner.
Each scanner model has the settings in slightly different places, and are sometimes labelled differently. This means I don’t have an exact setting that you need to change, you will need to check on the scanner to find the correct setting.
