* +5V BUS and GND BUS are used for bus termination. Some devices, like optical transceivers
(RS485 to fibre optics) might require external power supply from these pins. RTS is used in some
equipment to determine the direction of transmission. In normal applications only A-Line, B-Line
and Shield are used.
