Overview
A USB to RS-232 converter is a compact adapter that enables modern computers and devices with USB ports to communicate with legacy equipment that uses an RS-232 serial interface.
It’s widely used in industrial automation, telecom systems, point-of-sale terminals, and networking gear where traditional serial communication is required.
By bridging USB and RS-232 standards, this converter makes it easy to connect devices like modems, PLCs, serial printers, and other serial peripherals to USB-only computers.
