Features

Connects a Printer, Router or Other DTE Serial Device to Your Computer’s USB-A PortThis 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.
COM Retention Feature for Convenient Reassigning of COM Values to PortsThe 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 DB9­to-terminal-block adapter is included for making hardwire connections.
Double Shielding Protects Your Data from Destructive Line NoiseFoil 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 WarrantyThe U209-30N-IND is backed by a 3-year warranty, ensuring reliability and performance.
