How do RS-485 nodes work?

The RS-485 standards suggests that its nodes be networked in a daisy-chain, also known as party line or bustopology (see Figure 3-1. In this topology, the participating drivers, receivers, and transceivers connect to a maincable trunk via short network stubs. The interface bus can be designed for full-duplex or half-duplex transmission

What is an industrial RS-485 cable?

Industrial RS-485 cables are of the sheathed, unshielded, twisted-pair type, (UTP), with a characteristicimpedance of 120 W and 22–24 AWG. Figure 5-1 shows the cross-section of a four-pair, UTP cabletypically used for two full-duplex networks.

What are RS-485 design guidelines?

This application report presents design guidelines for engineers new to the RS-485 standard that can help themaccomplish a robust and reliable data transmission design in the shortest time possible. RS-485 is an electrical-only standard.

Why do RS-485 applications benefit from differential signaling over twisted-pair cable?

RS-485 applications benefit from differential signaling over twisted-pair cable, because noise from externalsources couple equally into both signal lines as common-mode noise, which is rejected by the differentialreceiver input.
