Our USB to RS422/RS485 adapters are an easy way to connect RS422 or RS485 devices to a USB port your computer.

Each port can be set as RS422 or RS485 allowing devices using either of these protocols to be connected. Each port has options such as termination and biasing and indication LEDs for Tx and Rx for easy diagnostics.

With a variety of port numbers and enclosure styles and easy to install drivers for a range of operating systems, these adapters are ideal for adding one or more RS422/RS485 ports to your computer.

  • Based on the renowned FTDI USB-Serial chipsets and drivers
  • Microsoft Windows® WHQL-certified, macOS and Linux drivers
  • Each RS422/RS485 port can appear as a Virtual Com Port allowing easy use with existing application programs
  • Multi-port units create a separate COM port for each port with separate settings (such as baud rate and flow control) per port
  • Ports can also be accessed using the FTDI D2xx DLL functions
  • Signals (note that modes and signals may vary between models)
    • RS422: TxD+, TxD-, RxD+, RxD-, GND, RTS+, RTS-, CTS+, CTS-
    • RS485 4-wire: TxD+, TxD-, RxD+, RxD-, GND
    • RS485 2-wire: Data+, Data-, GND
