## Long description

The StarTech ICUSB2321F is a 1-port USB to Serial RS232 adapter cable that converts a USB 1.1 or 2.0 Type-A port into a DB-9 serial port. Equipped with an FTDI chipset and COM retention, the 0.2 m black cable provides a reliable connection for serial peripherals, legacy equipment, POS systems and industrial devices without requiring an external power adapter.
Advantages
The FTDI chipset offers broad compatibility and advanced customization options not always available with other chipsets. COM retention ensures the adapter retains the same COM port assignment after disconnects or system reboots, simplifying device management. The compact, USB-powered design supports easy installation and portability while maintaining stable serial communication.
Suitable for
Connecting DB-9 serial devices to USB-equipped computers
