"High Speed" USB Serial Adapter

Looking for a way to connect your serial devices to a USB port on your PC? The Keyspan "High Speed" USB Serial Adapter is a simple, inexpensive, and reliable way to make this connection.

The Adapter is ideal for use with modems, digital cameras, ISDN terminal adapters, graphics tablets, PDAs, bar code scanners, label printers and other serial devices which require an RS-232 connection.
