Explanations on bus commands

1) Highbyte
0 0 D11
D0 ­ D11 = distance value 0 ­ 4095 (according to the set measuring range)
2) Byte
0 D6 D5
3) Highbyte
0 GT D11
D0 ­ D11 = distance value (0 ­ 4095)
GT = Good Target
4) Highbyte
0 1 D11
D0 ­ D11 = distance value (0 ­ 4095)
Bit6 = 1: High byte
Bit6 = 0: Low byte
5) After input of "?", the sensor setting is transmitted as follows:
