USB to RS485 Serial Port Converter Cable


USB-RS485 cable provides a convenient and reliable solution for connecting RS485 devices to a computer via USB. It incorporates FTDI’s FT232R chipset for smooth communication and offers ESD protection, LED indicators, and industrial-grade construction for enhanced performance and durability.


FTDI Chip USB to RS485 Cable with TX/RX LEDs is a converter cable that allows you to interface between a USB port and an RS485 serial interface. Here are the main features and specifications of the cable:

  1. USB to RS485 Interface: The cable provides a USB to RS485 serial interface, allowing you to connect devices with an RS485 interface to your computer via USB.
  2. FTDI FT232R Chipset: The cable utilizes the FT232R chipset, which provides a reliable USB to asynchronous serial data transfer interface.
  3. ESD Protection: The RS485 I/Os are protected against ESD (Electrostatic Discharge) with up to ±15kV Human Body Model (HBM) and ±15kV EN61000-4-2 Air Gap Discharge, as well as ±8kV EN61000-4-2 Contact Discharge.
  4. LED Indicators: The transparent USB connector features LEDs that provide a visual indication of power and transmit/receive data traffic.
  5. Compatibility: The cable is compatible with all Windows and Mac OS versions, including Windows 10 and Mac OS X 10.12 (Sierra).
  6. Industrial-Grade Materials: The cable is built with high-quality industrial-grade materials, ensuring durability and longevity.
  7. Cable Outputs: The cable has six outputs: GND (Black), Data- (Yellow), 5v Power (RED), Terminator 1 (Brown), Data+ (Orange), and Terminator 2 (Green).
  8. Terminal Resistor: There is a 120Ω terminal resistor connected between Terminator 1 and Terminator 2 within the cable. This resistor helps to terminate the RS485 bus properly.
