The StarTech ICUSB232 USB to RS232 DB9 Serial Adapter provides an external, plug‑and‑play RS‑232 interface that adds a DB9 serial port to a Mac or PC laptop or desktop via a single USB connection. It is powered directly from the USB port and uses an FTDI USB UART chipset for reliable serial communication. This 1‑port adapter delivers a DB9 RS‑232 connection that lets you communicate with legacy serial devices as if your computer had a built‑in DB9 port. Typical applications include connecting RS‑232 equipment such as modems, instrumentation, data loggers, or test instruments to modern computers.
