Omron NB5Q Barcode scanner input

Hey all.
Have a Omron NB5Q HMI, looking to integrate a handheld RS232 barcode scanner to input codes.
All well and good for the numeric input fields, under 'keyboard settings' I changed 'other input methods'. However how do I then allocate the barcode scanner on port 1 or 2 then be referenced to the string input field?
Cheers

The above link may help you out. I have not done this with an NB HMI but with other HMI units.
