1.TCP/IP Communication
2.RS485 Communication
The background PC software is able to communicate with the system according to two protocols(RS485 and TCP/IP) for data exchange and
remote management. The communication cable should be as far away from high-voltage lines as possible. Do not keep the communication cable
in parallel with power cords or bind them together.

Notes：
4) To enhance the stability of communication , it is necessary to keep place 8 of DIP when the bus is longer than 300m switches of
2) Considering stability of communication, it is recommended the length of RS485 bus is less than 600m
