objects. Parameter settings are made via the serial interface. The command to achieve this is Q1w_x_y_z or
Q2w_x_y_z (where “_” is equivalent to space, 0x20 hex), see Chap.
10.3.13 . The logic behavior of the switch-
ing output is determined through the parameter “z“, see Fig. 15 .

If:
- z = 1, increasing distance
ƒ
Output switches from LOW to HIGH, if w + y/2 is exceeded,
ƒ
Output switches from HIGH to LOW , if w + x + y/2 is exceeded.
- z = 0, decreasing distance
ƒ
Output switches from HIGH to LOW , if w + x -y/2 is fallen below.
ƒ
Output switches from LOW to HIGH, if w - y/2 is fallen below.
