Note:
It is suggested to use RS485E equipment under recommended value for long-term stable Equipment will not damage when working under limit value, but may result in performance degradation. Do not exceed the limit value, otherwise it may damage the equipment.
RS-485 bus wire should be 2-core shielded twisted pair copper wire, of diameter 0.5 to 0.75 millimeters, impedance 38 to 88 ohms / km, capacity of 30 to 50 nanofarad / km, pitch is 20mm (if wire distance is not more than 500 meters, the standard can be appropriately lower, but must be twisted pair)
