2.2. 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 RS485 device. The cable maximum length is 1200 meters.
Need to add 120Ohm terminal resistor for over 300 meters.

2.3. RJ45 Interface

Ethernet port is 10M/100M adaptive, support AUTO MDI/MDIX which means it support direct
connecting to PC with Ethernet cable.
