You can configure each input port as either Toggle, Command or Selector. Add a new control by clicking on the button at the bottom, right of the dialog for control type you wish to add, Selector, Toggle, or Command:
![DR4 Logic In](../Resources/Images/ProcessingWorkspace/DR4LogicInAddControls_710x447.png)
If you select Toggle, you can choose whether the toggle Type is Latching or Momentary using the drop-down menu. Latching is the default and causes the control to be read-only, following the state of the signal on the Logic In port. Momentary is intended for use with momentary switches and causes the toggle control to change state whenever the Logic In port signal transitions from high to low. When configured as Momentary the toggle control is not read-only, allowing other controls that are linked to the Logic In toggle to change the toggle state.
If you select Selector, you can choose the Number of Ports to use. If the number of ports selected is greater than one, you can also choose the type of selector, One-Of or Binary, in the Type drop-down menu. For binary controls, you can also choose the number of selections allowed for the selector.
