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 ...

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 ...

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.

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have ...
