Caiti,
This Brian Sorensen from c-Systems.
The scanners use a USB Serial Driver, and you must also scan a setup barcode to program the USB COM port emulation.
After the scanner is installed into Windows, open Infinity, choose Tools, then Devices, then Bar Code Reader, and then the correct COM port.
To get the correct driver, and the setup barcode, contact our Customer Support department, and they can assist.
