C0 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must
be send in succession. ( Save the parameters when power-down )
Three C1 are sent in hexadecimal format. The module returns the saved parameters and must
be send in succession.
C2 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must
be send in succession. ( Do not save the parameters when power-down )
Three C3 are sent in hexadecimal format. The module returns the version information and
they must be send in succession.
Three C4 are sent in hexadecimal format. The module will reset one time and they must be
send in succession.

In instruction mode（M0=0，M1=1） ，
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 18 50 50.
In instruction mode（M0=0，M1=1）,
User gives the module instruction (HEX format): C3 C3 C3.
Module returns its present version number, for example C3 61 xx yy.
61 here means the module model (E61 series); xx is the version number and yy refers to the other module features.
In instruction mode（M0=0，M1=1）,
User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time.
During the reset process, the module will conduct self-check, AUX outputs low level. After reset completing, the
AUX outputs high level, then the module starts to work regularly which the working mode can be switched or be
given another instruction.
