Add eight RS232 serial ports to any notebook or desktop computer using a single USB port

The ICUSB2328 8 Port USB to Serial RS232 DB9 Adapter Hub lets you connect up to eight RS232 serial devices to your Mac or PC, laptop or desktop computer through a single USB port, as though the computer offered integrated DB9M serial connectors.
