Add two serial RS232 ports with COM retention to your desktop computer or laptop via USB.

The ICUSB2322F 2-Port USB-to-Serial RS232 Adapter Cable with FTDI chipset and COM retention converts an existing USB 1.1 or 2.0 port into 2 serial RS232 DB9 ports for connecting, monitoring, and controlling serial devices. This compact adapter features COM retention, which automatically preserves the COM port values after disconnecting and reconnecting the cable to the host computer. The same applies after a system reboot. Unlike most USB-to-serial adapters, this one uses an FTDI chipset, allowing for additional custom settings, advanced features, and compatibility that may not be offered by other solutions. The USB-to-serial adapter is compatible with a variety of operating systems, including Windows, Windows CE, Mac OS, and Linux, making it easy to integrate the product into mixed environments.
