+5V and GND_BUS are bus terminators. Some devices, such as the optical transceiver (RS485),
may need to obtain power through these pins.
On some devices, the transmission and receiving directions are determined by RTS. In normal
applications, only A-Line, B-Line, and the shield layer need to be used.
