The module is completely self-powered from theР’В USBР’В bus. There are no command structures, whatever is sent to the Virtual COM Port is automatically converted toР’В RS485Р’В and vice versa.

This is an USB to RS485 Converter Adapter module which supports WIN7, XP, Vista, Linux, Mac OSР’В and provides an easy to use RS485 interface by means of using COM port in the computer. It is bidirectional and half duplex and has data transfer rate of 2.5 Mbps. For using RS-485 module with microcontrollers, a module called 5V MAX485 TTL to RS485 which is based on Maxim MAX485 IC is needed as it allows serial communication over long distance of 1200 meters. RS-485 Module can be connected to any microcontroller having serial port. RS-485 is faster compared to I2C protocol.Another advantage of the RS-485 is immune to the noise as they use differential signal method to transfer.Can have a maximum of 32 devices connected to RS-485 protocol.The main advantage of RS-485 over RS-232 is the multiple slave with single Master while RS-232 supports only single slave.It transfers data up to 1200-meter maximum. It also provides maximum data transfer distance compared to RS-232 protocol.RS-485 supports higher data transfer rate of 30Mbps maximum.It provides a Half-DuplexР’В communication when using two wiresР’В and Full-DuplexР’В requires 4 fours wires. So what is this differential signal transfer method?Р”Вifferential signal method works by creating a differential voltage by using a positive and negative 5V. It uses a technique called differential signal to transfer binary data from one device to another. RS-485 is an asynchronous serial communication protocol which doesnРІР‚в„ўt not require clock. Also learn more about various Serial Communication protocols here. LetРІР‚в„ўs begin by exploring some background about the RS-485 and Modbus. Serial Communication Between STM32F103C8 and Arduino UNO using RS-485.RS-485 Serial Communication between Raspberry Pi & Arduino UNO.RS485 can also be used with other controllers for serial communication: Since this tutorial uses RS-485, it is recommended to first go through RS485 Serial Communication between Arduino Uno and Arduino Nano. These LEDs and servo motor are connected with Slave Arduino and controlled by sending values using Master Modbus Software.

Here we install Simply Modbus Master Software in PC and control two LEDs and Servo Motor by using RS-485 as transmission line. This tutorial is about using RS-485 Modbus communication with Arduino UNO as Slave. Modbus RTU will be used in this tutorial. The only difference is that the bytes being transmittedР’В over the wire are presented as binary with RTU and as readable ASCII with Modbus RTU. Modbus RTU and Modbus ASCII talks the same protocol.

What is the difference between Modbus ASCII and Modbus RTU?
