A quick and easy way to expand your PC's port count and to adapt serial devices to your USB PC. Edgeport USB-to-Serial converters are intelligent expansion units that connect to a PC, thin client or server via a USB port. They provide one, two, four, eight or sixteen serial ports, as well as parallel and USB ports on some models. Compatible with most Windows operating systems.
