Wiring Notes:
1. 485 communication line must use shielded twisted pair, preferably multiple strands for spare, the longest is not more than 2500 meters.
2. The wiring should be as far away as possible from high voltage wires, not parallel to power lines, and not to be bundled together.
3. 485 bus must be a hand, in, hand bus structure, and resolutely eliminate star connection and bifurcation connection.
4. If there are more than 30 controllers or the cable length is greater than 500 meters, it is recommended to use a 485 repeater.
5. The AC, powered equipment and the chassis must be grounded and well grounded.
6. the GND ground of all 485 devices with shielded wires.
