Connecting Digital Inputs
Digital inputs are used for connecting switches and sensors. By default, they are ground-controlled.
- Connect one of the wires from a momentary switch to the common
GND(ground) terminal. - Connect the other wire to the desired input terminal (e.g.,
IN01). - Pressing the switch will short the input to ground, which will be interpreted as an "on" signal.

GND or +
The default input behavior (ground-controlled) can be changed via the internal switch. Please see the switch location below.
- Down (Default): GND control.
- Up: High-potential control.
