WHY CHOOSE THIS PRODUCT?

• The ICUSB2321F is designed for organizations that need to retain RS232 connectivity while modernizing computers and workstations that no longer include native serial ports. Its FTDI FT232RL chipset, COM retention and 115.2 Kbps maximum baud rate provide a more deployment-focused solution than a basic USB-to-DB9 cable, while the 1.8 m integrated cable keeps the installation simple and USB power eliminates an external adapter. Compatibility across Windows, Windows Server, macOS and Linux supports mixed IT environments, while TAA compliance and the two-year warranty make it suitable for structured enterprise procurement, replacement programs and long-term legacy-device connectivity.
