Tripp Lite by Eaton USB to Null Modem Serial FTDI Adapter Cable with COM Retention (USB-A to DB9 M/F) 18-in. (45.72 cm)

The U209-18N-NULL USB to Null Modem Serial FTDI Adapter Cable (M/F) allows you to connect a DTE serial device to a computer, laptop or tablet with a USB-A port. It supports data transfer speeds up to 256 Kbps-twice as fast as a built-in serial port. It solves DCE/DTE conflicts without additional cross-wired serial cables or adapters. No external power source is required. The compact 18-inch cable tucks away in your backpack or laptop bag for use anywhere.

The hot-swappable U209-18N-NULL with built-in FTDI chipset offers COM retention. It automatically reassigns the same COM port values to each port in case the cable is disconnected or the system is rebooted.

Premium foil and braid shielding delivers reliable, error-free signal quality and protection from EMI/RFI line noise. Molded nickel-plated connectors with gold-plated contacts ensure excellent conductivity. Integral strain relief ensures the cable and connectors last a long time. Works with Windows, Mac and Linux computers.

More from the Manufacturer

COM Retention and FTDI Chipset for Optimum Functionality

After initial installation, the U209-18N-NULL retains its assigned COM port values. If the cable is disconnected or the system is rebooted, the same COM port values will be reassigned to the port once the connection with the host computer is re-established. An integrated FTDI FT232RL chipset supports advanced features and compatibility.

Better than built-in serial ports, the U209-18N-NULL transfers data twice as fast—up to 256 Kbps. This 18-inch cable is also portable. It’s small enough to fit in your laptop bag and does not require external power.

Promotes Dependable Signal Transfer

Quality construction provides reliable, error-free signal transfer. The U209-18N-NULL has premium double shielding to eliminate cross-talk and reduce EMI/RFI interference. Molded nickel-plated connectors, integral strain reliefs and a flexible PVC jacket provide durability for a long service life.

Supports Broad Compatibility and Backed by a 3-Year Warranty

The U209-18N-NULL works with Windows, Mac and Linux and Android operating systems. Android devices must support USB Host Mode (OTG) and require a USB OTG cable to connect to this adapter cable.
