Abstract:
1. A power machine capable of being detachably coupled to an attachment comprising: a frame, an operator compartment supported by the frame, and a joystick controller disposed in the operator compartment, the joystick controller configured to generate movement signals in response to operator movement of the joystick controller; an electronic machine control unit configured to receive the movement signals from the joystick controller and control machine functions; a serial communication network coupled to the electronic machine control unit and configured to be coupled and communicate with an electronic attachment control unit that is disposed on the attachment and is configured to control movement of the attachment; and a state selection input disposed in the operator compartment to select one of at least two operational states including a first operating state and a second operating state, wherein the electronic machine control unit is configured to control operation of machine functions in response to the movement signals while in the first operating state, and wherein the electronic machine control unit is configured to allow the electronic attachment control unit to control operation of the attachment, in response to the movement signals while in the second operating state, by refraining from controlling operation of machine functions in response to movement signals that would cause the electronic machine control unit to control operation of machine functions in the first operating state so that the electronic attachment control unit is free to control the attachment in response to the movement signals while in the second operating state; wherein the power machine is capable of being in electrical communication with the electronic attachment control unit so that the electronic attachment control unit can receive the movement signals from the joystick controller via the serial communication network.
