Instruction
0x09 is the length of the instruction, refers to the
number of the bytes afterwards.
0x02 is the instruction
Power controller has some
message to Controller:
(When
the data mode
delivered by Controller
has some mistakes or
the receiving buffer area
was covered.)

E: Error
0x01 is the length of the instruction
0x02 is the instruction
No message from the power
controller to Controller: 02 00
Instructions:
1.
The commands delivered by Controller to network equipment are separated by 00 Hex,that is,it works as
the ending of the former command and the beginning of the following one.00 Hex is the data format of nine,
and the ninth one is zero; When receive this data, the indicating needle will do a zero clearing.
2. The bytes of the commands are all 9N1,and the ninth one is 1,refer to the above when come in front of
concrete commands.
3. The commands listed above are all sent out in reverse-code manner.
