Wiring Notes:
1. 485 communication lines should be used with a sealed twisted pair. It is recommended to use multiple strands as a spare. The longest length is less than 2,500 meters.
2. The wire should be as far as possible from the high voltage wire, not parallel to the power line, and not bundled.
3. 485 buses must be a handin-hand bus structure to eliminate star and branch connections.
4.If you have more than 30 controllers or the length of the cable is more than 500 meters, we suggest you use 485 repeater.
5. AC power supply and chassis must be ground and ground sufficiently.
6. Connect the GND Ground on all 485 devices with shielded wire.
