The PC send : 40,30,31,52,45,30,30,adrH,adrL,lthH,lthL,CRH,CRL,0D (total
14 bytes)
40 : the start byte

CRCH CRCL : CRC
0D : the end byte
The adr is the start address(00
~
1BH
)
,1th is the count of the byte. The
table is the relation of the adr and parameter.

If adr>1BH or adr+1th>1BH, the return the error code: 40,30,31,52,45,2A,2A,CRH,CRL,0D
The 2A 2A is the error sign
If the address range is correct then the instrument will send back data :
40,30,31,52,45,D1,D2,D3,
