Changing from a terminal type that supports a barcode scanner to one that does not causes the Source and Symbology selections to be disabled in the program designer. However, the original settings are not lost. If you later change back to a terminal type that does support scanning, the original settings are preserved.

If you select a barcode symbology, and change to a terminal type that supports scanning but not that specific symbology, you will need to edit the program and change those symbology settings.
