Product information

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
  • Point-of-sale systems and retail peripherals
  • Legacy equipment and industrial control devices
  • Mixed OS environments (Windows, macOS, Linux)

Key specifications

  • Model: StarTech ICUSB2321F
  • Interface: USB 2.0 A to RS-232 DB-9
  • Ports: 1 serial port (DB-9)
  • Chipset: FTDI
  • Cable length: 0.2 m
  • Color: Black
  • Weight: 0.09 kg
  • Features: COM port retention
  • MPN: ICUSB2321F
  • EAN: 0065030843485

How to use

Connect the DB-9 serial connector to your serial device and plug the USB-A connector into an available USB 1.1 or 2.0 port on your computer. Install any required drivers for your operating system if prompted; the FTDI chipset is supported on Windows, Windows CE, macOS and Linux. Once the driver is installed, the adapter will be assigned a COM port which can be used by terminal, POS or control software to communicate with the serial device.

Usage recommendations

For reliable operation, use a direct USB port on the host computer rather than an unpowered USB hub. Keep drivers up to date from the FTDI or StarTech.com support pages to ensure OS compatibility and access to advanced chipset features.
