Features

Connects a Modem or Other 9-Pin Serial Device to Your Computer’s USB-A Port
This USB to serial converter turns your computer’s USB port into a DB9 port capable of connecting RS-422 and RS-485 serial devices, such as modems, handheld scanners and GPS systems. No external power source is needed. Just connect the included USB cable between the U208-001-IND and your computer, and insert the included CD into your computer’s CD drive in order to launch the driver. You’ll be able to configure and share data among point-of-sale equipment and other serial devices. LEDs indicate when serial data is being sent or received.
Independent DIP Switch for Easy Port Configuration
The U208-001-IND’s sole serial port can be set to automatically detect an RS-422 or RS-485 device by adjusting its DIP switch setting. The port can also be set specifically for use in 4-wire mode.
COM Retention Feature for Convenient Reassigning of COM Values to Ports
This USB to RS-485 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 cable auto-detects and auto-switches RS-422 and RS-485 devices. It also supports RS-485 auto-transceiver turn around with unique featured ATTA hardware.
Rugged All-Metal Housing Designed to Last in Harsh Industrial Applications
The wall-mountable USB to serial converter with an industrial-grade steel enclosure offers electrostatic discharge (ESD) protection to ±15kV. It supports serial communications speeds up to one Mbps and USB 2.0 specifications, though it is backward compatible with USB 1.1 devices.
2-Year Warranty
The U208-001-IND is backed by a 2-year warranty, ensuring reliability and performance.

Questions & Answers

COM retention allows the same COM port number to be automatically assigned each time the serial adapter is connected to a USB port on your system (or your system is rebooted). Without COM Retention, you would have to remember which port to connect the adapter.
