The cuecat barcode scanner is considered a "wedge" device. Which means it goes between the PC's Keyboard port and the keyboard itself. That way, when you scan a barcode, it's the same as if you had typed the contents of the barcode(characters) on the keyboard yourself.
Considering that the keyboard is IR, I have no idea how you would interface the keyboard part of the curcat to the Audrey's IR input thingy at the bottom of the audrey. Probably is relatively simple, it will just take some trial and error to see if the wires coming out of the IR "eye" are equilivant to the wires coming out of cuecat (and the small matter of getting them connected in the right order).
Good Luck, If you have any success, please post it.
