The USB adapter Startech 1P6FFC-USB-SERIAL is a converter cable designed to reliably connect RS-232 serial devices to USB ports on a modern computer, offering a practical solution to keep using industrial, communications or laboratory equipment based on a DB9 interface. This black model features a USB-A connector on one end and a male DB9 serial connector on the other, allowing direct connection of peripherals such as terminals, modems, barcode scanners, PLCs or POS systems without additional hardware. It offers a 2 m cable length, providing enough reach to organize installations on desktops, racks or industrial environments while avoiding strain on the connectors. Based on an FTDI chip, it is designed for stable, compatible serial communication, with typical support for modern operating systems and environments such as Linux, making integration easier in mixed workstations or legacy applications; the COM retention function keeps the same port number assigned after reconnecting the adapter, simplifying the setup of specialized software that depends on a fixed COM port. The Straight pinout design follows the standard RS-232 signal mapping, ensuring interoperability with most serial devices without extra adapters. A user manual is included for guided installation and correct port identification in the system, helping reduce deployment time in technical or professional environments. Thanks to its combination of USB compatibility, DB9 connectivity and 2‑meter cable, this Startech adapter is a functional, stable tool for connecting RS-232 serial devices to current equipment.
