A) Start Code: 485-A 0x55

Start Code: 485-B 0xAA

B) 2 device address : 4 Bytes(ID0 is the highest , ID3 is the lowest),With a common

control, the device address is 0x0000000000. If the control occurs together and

the ID is not explicitly mentioned, 485-B does not respond.

C) Check code: Checked by CRC16(start code+device address + Command code+
