A KeyKing controller's additional inputs and outputs are configured in the ACFA Intellect Software System on the TC3XY Extra Input and TC3XY Extra Output objects' settings panes. These objects are created based on a TC3XY Controller object on the Hardware tab of the System Settings dialog.

To configure an additional input (additional output) on a KeyKing controller, do the following:

1. Go to the TC3XY Extra Input- or TC3XY Extra Output object's settings pane.
   
2. Enter the input (output) number of the KeyKing controller in the Number field (1).
3. Select the normal state of the KeyKing controller's input (output) from the State dropdown list (2).
4. Click the Apply button (3).

This completes the configuration of the KeyKing controller's additional input (output).
