7.3 Reading Version Number
Instruction format
Description
C3+C3+C3
In configuration mode（M0=1, M1=1, M2=0）,
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 0071 XX1 XX2 XX3 XX4 XX5.
70 here means the module model (E70 series); xx1 is the version number and XX2 XX3 XX4 XX5
refers to the other module features.
7.4 Reset Instruction
Instruction format
Description
C4+C4+C4
In configuration mode（M0=1, M1=1, M2=0）,
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 completed,
the AUX outputs high level, then the module starts to work regularly when the working mode can be
switched or be given another instruction.
