xxxb: Range number depending on the directory number
000b: Range 0 -> from 000 to 127
001b: Range 1 -> from 128 to 255
010b: Range 2 -> from 256 to 383
011b: Range 3 -> from 384 to 511
100b: Range 4 -> from 512 to 639
101b: Range 5 -> from 640 to 767
110b: Range 6 -> from 768 to 895
111b: Range 7 -> from 896 to 999 (binary values over 999 are ignored).
Method of calculation:
1) range = value from the above table in relation to the directory number
2) value = directory number - range x 128
Example of a frame triggering directory 278 in player number 6:
Directory number = 278
1) 278 is in range 2 (from 256 to 383) - table above
2) Value = 278 - 2 x 128 = 22
The frame is:
Byte 1: 10000110b (86h) : status byte, player number 6
Byte 2 : 00100001b (21h) : range 2, go to command (0001b)
Byte 3 : 00010110b (16h) : value 22
