RS-485 Network Installation Guidelines
To ensure stable and reliable communication, follow these recommendations when
installing the RS-485 network:
1) Topology Always use bus (daisy-chain) topology.
2) Cabling Use shielded twisted-pair (STP) cable for the RS-485 communication
lines and B). RS-485 line
termination configured using DIP switch SW2. The shield should properly grounded one point only. Star ring topologies are
not permitted, they cause signal reflections and degrade communication
quality.
– the sensor used standalone device is
located the end the RS-485 bus (daisy-chain
topology), set both switches the position.
4) Termination The RS-485 line must terminated both ends.
Do not route them the same conduit near high-current cables prevent
electromagnetic interference (EMI).
– the sensor installed the middle the RS-485
bus, set both switches the position opposite the
ON marking (OFF position)
