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 45.72 cm (18-in.) 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.

Great Product
Easy and simple to use. Box labels exactly what kind of adapter cable it is, so no need to try a bunch of different cable to connect to what is needed. Length is good to work closely with the thing needed to communicate with, without being too close.

Simply Works.
Using this product was super simple. MY laptop does not have a disk drive for the driver disk, but the website was quick to get me to the downloads page to install. Once installed, the cable does exactly what I need. This cable works with older HP switches like a dream.

Love This Adapter!
I can't express how elated I was to FINALLY received this adapter cable & it worked. In my manufacturing plant, we're barely hanging on to technically archaic multi-spindle fastening systems with serial communication ports. So although we were grateful for also finally receiving upgraded laptops for troubleshooting tooling related issues, we couldn't without adapter cables. The only thing I regret about this purchase is the overall length. If you have a 3 ft long version, I would love that part# so I could order it.
