4. Wiring Diagram
Wiring layout suggestion:
1. Hand-in-hand wiring is highly recommended, yet star-topology or tree-topology is strongly deprecated
2. RS-485 layout wire length shall not be longer than 300m, and 12pcs sensors are the maximum quantity layout in one circuit
3. A 4-pin shield wire or class 6 network wire is highly recommended for layout
4. Our sensor doesn’t have terminal resistance. if there’s an impedance matching problem inthe RS-485 bus, we recommend connecting 2 pieces of 120Ω resistance in the terminal
5. Detection of radiation
6. Detection Signal
The product detects human moving signals, and below is a description of the moving signals:
Moving signal: detect the human significant moving (walking) in the detection area.
7. Remote Control MH18
