A scalable solution for changing needs This rack-mountable USB serial hub (FTDI) lets you add eight serial ports (RS232), with full control from your desktop or laptop computer system using a single USB port. The daisy-chain function gives you a cost-effective and scalable way to increase your serial port count and expand as your needs grow, without investing in a more expensive serial hub.
