1. Start code: 485-A 0x55
2. Device address: 4 bytes (ID0 is the highest, ID3 the lowest) In the case of
common control, the device address is 0x0000000000. If the control is
carried out together and the ID is not explicitly mentioned, 485-B does
not react.
3. Check cod: checked by CRC16 (start code + address + command code +
command value).
