8.1 CREATOR Conference System Protocol Code Formats and Their
Descriptions
Communication protocol:9600.N.8.1
Control code:The codes below are Hex format codes.
Format:A0 [XX] 10 00 07 [YY] FF FF FF AF [ZZ]
Description:
◆
The [XX], [YY] and [ZZ] are 16 hexadecimal formats, where [YY] represents the ID mapping code;
◆ Algorithm: [ZZ]=FFFF- ([XX]+10+00+07+[YY]+FF+FF+FF), choose the last 16 HEX as the result;
◆ Adopt "128 bit" algorithm, whenever speech unit ID (number) increases 128, the ID mapping code
should increase 7F, ID mapping code [YY] high bit should increase 1, and [XX] increases 1.If the
speech unit ID (number) continues to increase, [YY] is to start increasing at 0, the value of [ZZ] is to
comply with the above algorithm, as follows shown in the table:
ID number of speech unit (10
hexadecimal format) ID mapping code of return
code (16 hexadecimal format) Serial return code (16 hexadecimal
format)
001 1 A0 10 10 00 07 01 FF FF FF AF DA
002 2 A0 10 10 00 07 02 FF FF FF AF D9

This table is the example list of the corresponding relationship between each coded speech unit
ID (number), serial code and the ID mapping code.
