In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

Dozens of serial data interfaces are used today. Most have been developed for specific applications. A few have become universal, such as I 2 C, CAN, LIN, SPI, Flex, MOST, and I 2 S. Then there’s ...

RS-485 is the chosen physical layer standard for numerous industrial communication systems, such as PROFIBUS systems, or for connecting devices like PLCs, SCADA systems, RTUs, or MODBUS systems.

The RS-485 standard defines a popular and widely used serial data interface and network that’s been in use for over 30 years. It’s found in factories, process control plants, building automation, and ...
