FTDI USB to RS-232 / RS-422 / RS-485 Pro Grade Configurable Adapter

USB to RS-232/422/485 Adapter

The USB to serial interface adapter offers an easy way to connect a DB9 serial device to a USB port. All configuration and electrical interface selections are handled through the driver, eliminating the need to open the enclosure to set jumpers or switches.

The serial port is software configurable for RS-232, RS-422, and RS-485 with the electrical interface settings maintained locally, allowing the host computer to be repaired or upgraded without reconfiguring the serial port.
