After input the baud rate required,press"clear"button confirm and finish the
communication parameter setting and back to weighing state.
In the parameter input process, press the "Accu"button, you can terminate the parameter
input, back to weighing mode.

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
