RS-485
RS-485 is a standard for serial communication that allows multiple devices to communicate over long distances. It is commonly used in industrial applications due to its ability to support multiple devices on a single network, making it efficient for connecting sensors, controllers, and other equipment.
The RS-485 standard uses differential signaling, which helps reduce noise and allows for reliable data transmission over distances up to 4,000 feet (1,200 meters). This makes it ideal for environments where electromagnetic interference is present, ensuring stable communication in various applications, including automation and building management systems.
