What is RS-485?

RS-485 is a robust and efficient serial communication standard designed for applications that require:

• Long-distance transmission

• Multipoint connectivity

• Strong noise immunity

Thanks to its reliability and flexibility, RS-485 is widely adopted in industrial automation, communication systems, and remote monitoring.

How Does RS-485 Work?

RS-485 transmits data using two signal lines (A & B), enabling:

• Half-duplex communication

• Excellent resistance to electrical noise

• Up to 32 devices on the same bus

• Each device has a unique address for accurate data exchange

When paired with the Modbus protocol, RS-485 becomes a powerful tool for efficient device communication and management across complex systems.
