Description
The Waveshare USB TO RS485 (C) converter provides bidirectional communication between USB-equipped host devices and an RS485 bus. Its FT232RNL interface chip supports data rates from 300 to 512000bps, while automatic hardware direction control eliminates the need for manual switching between transmission and reception. The converter is designed for industrial controllers, measuring instruments, Modbus RTU devices, automation systems, and remote monitoring applications.
The device features an isolated RS485 transceiver that reduces interference caused by ground potential differences between the host computer and the communication bus. Protection circuits include TVS diodes, 15kV ESD protection, surge protection rated at 600W according to the manufacturer, resettable fuses, and additional transient suppression components. An onboard 120Ω termination resistor helps reduce signal reflections on the RS485 bus.
The converter provides a USB-A plug and a three-position screw terminal labeled A+, B-, GND. Power is supplied at 5V through USB. RS485 communication is supported over distances of approximately 1.2km at low data rates and in multipoint networks containing up to 32 nodes. Waveshare recommends repeaters for installations with 16 or more devices. The converter supports Windows, Linux, macOS, Android, and WinCE using FTDI serial port drivers.
Three red status LEDs indicate the USB power connection and data transmission activity. The compact housing, USB-A plug, and screw terminals allow direct connection to a computer or installation through the included approximately 1.2m USB-A extension cable.
