Introduction
The ICUSB232FTN 1-Port FTDI USB to Serial Null Modem DCE Adapter Cable converts
an available USB 1.1 or 2.0 port into an RS232 Null Modem serial DB9 port for
connecting to a DTE serial device. Solving DCE/ DTE conflicts directly, without requiring
additional cross-wired serial cables or adapters.
This compact adapter features COM retention, allowing the same COM port value
to automatically be re-assigned to the port if the cable is disconnected and re-
connected to the host computer, or if the system is rebooted. The integrated FTDI
chipset supports additional customization, advanced features, and compatibility not
necessarily offered by other solutions.
Compatibility with a broad list of Operating Systems including Windows®, Windows CE,
Mac OS and Linux, makes this product easy to integrate into mixed environments.
