Overview

About the Tripp Lite U209-18N-NULL

View user manual

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.
