Abstract

A control system for customizing a relationship between an operator input at an input controller and a corresponding response of a work machine is disclosed. The control system includes an input controller operable to receive an operator input and generate a corresponding control signal. The control system also includes a hand-held programmable device having parameters stored therein. The parameters are adjustable to control responsiveness of a component of the work machine over a range of inputs at the input controller. The hand-held programmable device is operable to adjust the parameters in response to an input from an operator. A control module is disposed on the work machine and is operable to receive signals from the hand-held programmable device. The signals are representative of a desired relationship between an operator input to the input controller and a corresponding response of the work machine. The control module is also operable to receive the control signal from the input controller and process the control signal based on the signals from the hand-held programmable device.
