1 Port USB to Null Modem RS232 DB9 Serial DCE Adapter Cable
1 Port USB to Null Modem RS232 DB9 Serial DCE Adapter Cable with FTDI
StarTech ID: ICUSB232FTN
The ICUSB232FTN FTDI USB to Null Modem Serial Adapter Cable (1-Port) converts an available USB 1.1 or
2.0 port into an RS232 Null Modem serial DB9 port, 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 reassigned 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.
The USB to Null Modem adapter is compatible with a broad list of operating systems including Windows®,
Windows CE, Mac OS and Linux, making it easier to integrate into mixed environments.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
Perfect for IT Administrators looking to add legacy functionality to newer notebooks, PCs and servers that
lack an integrated RS232 port
