7.2 Reading Operating Parameters
Instruction format
Description
C1+C1+C1
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.
7.3 Reading Version Number
Instruction format
Description
C3+C3+C3
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.
7.4 Reset Instruction
Instruction format
Description
C4+C4+C4
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.
