front is high digit and low in the post
9 Decimal position
From right to left（0～4）
10 XOR checksum Higher four digits
11 XOR checksum Lower four digits
12 03(X0FF) End
Note: The confirmation of higher 4 digits and lower 4 digits XOR
checksum
XOR checksum operated in 16 hex byte way from byte 2 to byte 9. The high
4 and low 4 bits of checking result was conversion and transmit in ASCII code,
conversion method are as follows:
If less than, or equal to 9, then add 30h, will send a number of ASCII code,
for example: XOR checksum high 4 to 6, after adding 30h, 36h is ASCII code for
the 6 to send;
If higher than 9, then add 37h, will send a letter ASCII code, for example:
XOR checksum high 4 bits of B, plus 37h, the ASCII code for the 42h that is
sending B

Continuous communication format 2
There are 9 bytes in each frame data, and detail format please

9 0 or- symbol position
For example the current weight is -1.00，so the sending data is：
＝00.1000－＝00.1000－＝00.1000－＝00.1000－
