With its USB 2.0 Type-A male to DB9 male RS-232 configuration, it is ideal for IT professionals, engineers, and technicians who need to integrate serial-based equipment—like barcode scanners, modems, GPS units, or industrial automation systems—into contemporary computer systems that lack serial ports.

Features
The Tripp Lite USA-19HS stands out in the world of USB-to-serial connectivity due to its high-speed chipset and solid build quality.

It’s fully bus-powered, meaning it requires no external power supply—making it portable and efficient for field use. The adapter comes with a 3-foot integrated cable, an LED status indicator for activity monitoring, and includes a driver CD for quick setup, although plug-and-play installation is often supported in modern OS environments.
Advanced Options
Whether in server rooms, medical facilities, labs, manufacturing floors, or point-of-sale stations, the USA-19HS ensures uninterrupted communication between USB-equipped computers and serial devices. Tripp Lite has also validated this model for TAA compliance, making it suitable for use in government and corporate environments where procurement standards must be met.
