Chapter 9 Annex
9.1 Code Specification
Form: A0 [XX] 10 00 07 [YY] FF FF FF AF [ZZ]
Specification:
1. [XX]、[YY] and [ZZ] are all hexadecimal, and [YY] stands for ID code.[ZZ]=FFFF-([XX] +10+00+07+
[YY] +FF+FF+FF)
2. Arithmetic: [ZZ] =FFFF-([XX] +10+00+07+ [YY] +FF+FF+FF), get the low bit from the result.
3. Delegate unit set number form number 2, ID code form number 1, and progressive increase.
◆ Adopting 128 binary system arithmetic, every increase of 128 in Discussion unit number (S/N)
means 7F increase of ID code. ID code [YY] high bit increases a bit, at the same time [XX] plus one, if
Discussion number (S/N) constantly increases, [YY] should be increased from 0 again. [ZZ] will follow
the above arithmetic, as following chart.
