Rs485 arduino

This module (right) (See it here) can be used to send Arduino serial data over long distances (up to Km) using RS4signals. RS4is a physical connection standard for Serial data transfer. This port sends the data to a second remote Arduino over RS485.

Sometimes we need to connect Arduino boards located far away from each other. The RS4is a very convenient way to connect the boards with just wires, . DEV-12965: Our friends over at LinkSprite have made this nifty little RS4Shield. Arduino’s Dto Das Software Serial Ports to communicate with the shield.

This module interfaces an Arduino or similar microcomputer to RS-485. RS4is used for Serial Communications over longer distances than direct RS2or . The RS-4module for Arduino, Raspberry Pi and Intel Galileo allows users to. Please note that the source code shown in this.

Some time ago, I bought an Arduino in order to play with it: I was completely. Rs4together with modbus are one of the natural solutions.
