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.

Guest columnist Ian Doyle, product line manager for semiconductors at Bourns, describes how to provide suitable circuit protection for RS-485 ports. RS-485 is one of the most common interface ...

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 ...

Ratified in the early 80's as a new balanced transmission standard, RS-485 has emerged as the industry's seemingly eternal interface workhorse. Much literature has been written on the subject since, ...
