USB-to-Serial Adapter with DB25 Connector

The Tripp Lite U209-005-DB25 is a wired accessory that connects legacy RS232 peripherals to a computer USB port. It supports devices fitted with either a 9-pin DB9 or 25-pin DB25 interface. The adapter suits users needing to link older serial equipment such as PDAs, digital cameras, modems or ISDN terminals to modern laptops or tablets.

For legacy peripheral owners.

This product suits anyone who must attach RS232 hardware to a system lacking a built-in serial port. It is not for buyers who already have a functional native serial connection or who require an interface other than USB-to-RS232. Users needing multi-port expansion or industrial-grade isolation should look at different solutions.

Cable-only design requires no extra software

The bundle consists solely of the adapter cable; no driver disc or configuration utility is included. Plug-and-play operation on supported operating systems means the accessory adds immediate connectivity without installation steps. No bundled software changes the setup workflow for the target serial devices.
