2.3. RS485 Interface
RS485 use two wire links, A(DATA+), B(DATA-). Connect A(+) to A(+), B(-) to B(-) for communication.
Suggest to connect GND together when interference is very severe.
The RS485 interface support maximum 32 485 device, device. The cable maximum length is 1200
meters. Need to add 120Ohm terminal resistor for over 300 meters.
