RS-485 bus is the most popular communication method in industry. Compared with RS-232 bus, it is

able to transfer information in further distance with lower cost. Establishing an “Internet of Things” by

integrating RS-485 with Ethernet, which is the widely available in the world, in the hope that this

method will coordinate all devices with low cost and high efficiency.
