C0 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must be sent in
succession.
(Save the parameters when power-down)
Three C1 are sent in hexadecimal format. The module returns the saved parameters and must be sent in
succession.
C2 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must be sent 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
sent in succession.
Three C4 are sent in hexadecimal format. The module will reset one time and they must be sent in
succession.
Under transparent transmission mode, send three E2 in HEX format, the module will enter a 10s
parameter configuration window period, user could configure the module parameters in the 10s with C0
command, 10s later, the module will work with the new parameters.
Under transparent transmission mode, send three E3 in HEX format, the module will enter a 10s
parameter configuration window period, user could configure the module parameters in the 10s with
6-byte C0 command, 10s later, the module will work with the new parameters.

Under configuration,(M0=1,M1=1), send command (HEX format) to the serial: C1 C1 C1, the
module will return current parameter values, i.e.:
Under configuration mode (M0=0, M1=1, M2 =0), send command (HEX format) to the serial:
C3 C3 C3, the module will return current parameter values, i.e.: C3 00 28 10 0C 09 01 00;
The 00 28 means the module model number (E28 series), 10 means the version number, 0C
means the transmitting power, other values means other characteristics.
