一种颜色，“B”端接另一种颜色。
4、 RS-485 总线(从上位机通信口开始到任一被连接的仪表终端通信口)长不超过 1200
米。
Note:
1、Wiring should follow the wiring requirements;
2、Connect all the meter in the RS485 net work even some do not need to communication,
which is benefit for error checking and testing;
3、Use two color wires in connecting wires and all the A port use the same color.
4、No longer than 1200 meters of RS485 bus line.
