Explanations on bus commands
1) Highbyte Lowbyte
0 0 D11 D10 D9 D8 D7 D6 0 0 D5 D4 D3 D2 D1 D0
D0 ­ D11 = distance value 0 ­ 4095 (according to the set measuring range)
2) Byte

3) Highbyte Lowbyte
0 GT D11 D10 D9 D8 D7 D6 0 Q1 D5 D4 D3 D2 D1 D0
D0 ­ D11 = distance value (0 ­ 4095) Q1 = status of Q1
GT = Good Target
4) Highbyte Lowbyte
0 1 D11 D10 D9 D8 D7 D6 0 0 D5 D4 D3 D2 D1 D0
D0 ­ D11 = distance value (0 ­ 4095)
