5 | Description: | |
6 | Program sensor type for threshold detector inputs. | |
7 | Could be either "GND-Open" or "Supply-Open" mode. Y is a | |
8 | threshold detector input channel. Channels 0..7, 8..15, 16..23 | |
9 | and 24..31 has common sensor types. | |

15 | Description: | |
16 | Channel Y low voltage threshold. If sensor input voltage goes lower then | |
17 | this value then the threshold falling event is pushed. | |
18 | Depending on in_voltageY_sensing_mode the low voltage threshold | |
19 | is separately set for "GND-Open" and "Supply-Open" modes. | |
20 | Channels 0..31 have common low threshold values, but could have different | |
21 | sensing_modes. | |
22 | The low voltage threshold range is between 2..21V. | |
23 | Hysteresis between low and high thresholds can not be lower then 2 and | |
24 | can not be odd. | |
25 | If falling threshold results hysteresis to odd value then rising | |
26 | threshold is automatically subtracted by one. | |

32 | Description: | |
33 | Channel Y high voltage threshold. If sensor input voltage goes higher then | |
34 | this value then the threshold rising event is pushed. | |
35 | Depending on in_voltageY_sensing_mode the high voltage threshold | |
36 | is separately set for "GND-Open" and "Supply-Open" modes. | |
37 | Channels 0..31 have common high threshold values, but could have different | |
38 | sensing_modes. | |
39 | The high voltage threshold range is between 3..22V. | |
40 | Hysteresis between low and high thresholds can not be lower then 2 and | |
41 | can not be odd. | |
42 | If rising threshold results hysteresis to odd value then falling | |
43 | threshold is automatically appended by one. |
