Tripp Lite USB to Serial Adapter Cable (USB-A to DB9 M/M), 5-ft.

The U209-000-R USB-to-Serial Adapter Cable allows you to connect a 9-pin RS-232 serial device to a computer or laptop with a USB Type-A port. It works with modems, digital cameras, PDAs, ISDN terminals and other devices with a serial port. The U209-000-R supports data transfer speeds up to 230 Kbps—twice as fast as a built-in serial port. No external power is required, and the compact 5-foot cable tucks away conveniently in your backpack or laptop bag for easy traveling. Doubled-shielded design with gold-plated contacts, tinned copper braid and aluminum Mylar foil shield eliminates crosstalk and reduces EMI/RFI interference.
