The USBS 2201 serial communication converter allow you to establish serial communications at speeds up to 460.8 kbps without ever opening up your computer case. It also eliminates the need for such system resources as I/O ports and IRQs to support serial communications. The USBS 2201-I version includes optical isolation for protection against transients and ground loops.
The USBS 2201 requires a computer system that supports V1.1 USB in both hardware and operating system. It is powered from the USB cable, so you need no additional power supplies. These converters should normally be connected to a self-powered hub that is capable of supplying 50mA (USB 2201) or 100mA (USB 2201-I) of current per port.
