Communication Protocol 5.1 Data Format 5.1.1 Format There are two data types – Data 1, Data 2. The duration time for each data is 610us Data 1: The duration time of High Level is 400us, The duration time of Low Level is 210us. Data 2: The duration time of High Level is 210us, The duration time of Low Level is 400us. 5.1.2 Preamble Format The preamble is 1 byte. There are 8 bits in the preamble. It is made up of 4 high levels (610us) and 4 low levels (610us) as below figure. It is transmitted from high level.

The total is 64bits. The duration time for each transmission is 610us * 64 +x= 100ms. 5.1.3.3 If repeatedly transmit multi-group data, then the transmission duration time is 610us * 8 * 7=34.16 ms for each additional data. The preamble does not repeatedly be transmitted in each data.
