Frequency Inputs
Inputs/Outputs → Frequency Inputs
Frequency inputs read pulse signals from speed sensors, RPM pickups, and similar sources. Each input converts pulse frequency into a channel value such as wheel speed or engine RPM.
Configuration
Select a frequency channel from the list, then configure:
| Setting | Description |
|---|---|
| Output Channel | The channel that receives the calculated value |
| Pulses Per Revolution | Number of pulses per wheel or shaft revolution |
| Digital Input | Optional digital input for direction or validity |
| Filter | Signal filtering options |
| Offset Channel | Channel subtracted from the result, for example to zero a speed sensor. Clear removes it. The logged rate stays the same |
The hardware type of each input determines which pins on the display connector are used. Refer to the product datasheet for pin assignments.
Example
Wheel speed sensors on the rear axle might be configured as two frequency inputs — one for left rear and one for right rear. These channels can then feed Speed Fusion, Math Functions, or CAN transmit messages.
