Create your own keypad
If you want to create your own keypad with up to 22 customizable buttons, such as rugged buttons for outdoor use, you can connect the individual buttons to this unit, which is then connected to the DRB unit via a simple cable (via CANBus).

In an Addio system, 2 units can be connected, allowing you to have 22 unique functions in parallel across two identical keypads
