Tripp Lite U209-005-DB25 Usb to RS-232 Serial Adapter Cable

Product Description

The TRIPP LITE U209-005-DB25 is a USB to RS-232 serial adapter cable that converts a standard USB Type-A port to a DB25 serial interface. This cable allows a computer or laptop without a native serial port to communicate with RS-232 devices over a legacy serial connection. At 5 feet in length, it provides a practical reach for bench or rack installations. Technicians and integrators use this adapter when connecting laptops or modern workstations to serial-controlled equipment such as projectors, networking gear, industrial controllers, or other RS-232-dependent devices. The DB25 connector on the serial end is the standard 25-pin male configuration used in many legacy and commercial applications.

This adapter is suited for commercial AV, IT infrastructure, and industrial service environments where RS-232 control is still required. Common use cases include programming or configuring equipment via a serial console, connecting to commercial projectors with DB25 control ports, or providing a serial interface on a system that lacks one natively. The cable is well suited to AV integrators, IT technicians, and field service personnel working with legacy serial protocols on modern hardware.

Key Features

• Converts USB Type-A to DB25 RS-232 serial interface
• 5-foot cable length provides flexible reach for most bench and rack work
• Supports RS-232 serial communication for legacy device control and configuration
• DB25 25-pin serial connector for compatibility with commercial and industrial equipment
• Single-unit packaging for individual replacement or field kit use

Compatibility

Designed as a USB to RS-232 serial adapter for use with computers and laptops that require a DB25 serial connection to communicate with RS-232-controlled devices. Compatible with systems and equipment specifying a DB25 serial interface.

Installation Notes

Installation does not require trade licensing but may require driver installation on the host computer before the adapter is recognized as a serial COM port. Power down or disconnect the target serial device before attaching the DB25 connector to avoid unintended signal transmission. Verify that the host operating system supports the adapter chipset and that the correct COM port is selected in the controlling software before initiating communication.
