Thank you for your reply, Joe.
I wish to read 1D and 2D (QR) type barcodes, preferably with a wired scanner.
I actually gave the Dimex DS2208 barcode scanner a try and it worked fine with UniStream. I connected it via USB and the PLC accepted it as a keyboard meaning the user will have to press a text box and only then scan the barcode, which might be just fine for my application.
