Tripp Lite U209-30N-IND USB to RS485/RS422 FTDI Serial Adapter Cable with COM Retention (USB-A to DB9 M/M), 30-in. (76.2 cm)

Connects a Printer, Router or Other DTE Serial Device to Your Computer’s USB-A Port
This 30-inch USB to RS485 adapter cable turns your computer’s USB port into an RS422 or RS485 serial port and avoids the expense of upgrading your reliable serial devices. No external power source is needed. Just connect the cable to your computer and insert the included CD into your computer’s CD drive in order to launch the driver and assign the cable a COM port. It supports USB 2.0 specifications and data transfer speeds up to 230 Kbps, which is almost twice as fast as a built-in serial port. It is backward compatible with USB 1.1 devices. Note:
The U209-30N-IND will pull power from the host device. If connected to a USB2.0 host, 0.5A of max power will be provided. If connecting to USB3.0 host, 0.9A of power will be provided. If your device is not working properly, be sure you are connecting to the proper USB port.

COM Retention Feature for Convenient Reassigning of COM Values to Ports
The hot-swappable USB to RS422 adapter with built-in FTDI chipset offers COM retention. It automatically reassigns the same COM port values to each port, so when the cable is disconnected or the system is rebooted, no additional configuration is needed. The FTDI USB to serial adapter also supports RS485 auto-transceiver turn around with unique featured ATTA hardware, as well as remote wake-up and power management. A DB9-to-terminal-block adapter is included for making hardwire connections.

Double Shielding Protects Your Data from Destructive Line Noise
Foil and braid shielding helps fight against electromagnetic interference and radio frequency interference (EMI/RFI) that impedes your signal and can distort or destroy data. The auto-sensing feature solves DCE/DTE conflicts without the need for cross-wired serial cables or adapters.

3-Year Warranty
The U209-30N-IND is backed by a 3-year warranty, ensuring reliability and performance.
