I think James already hit it on the head. The robot isn't reporting all 8
barcode chars, therefore, NBU isn't using the "Chars" rule you have.
Besides, the default behavior for NBU is to use the right most 6
digits/chars of the barcode as the media id. The rule you are using was
introduced so people could strip off the media identifier.
So, check with your hardware vendor to see if they can enable/disable the
display of the media identifier.
