Abstract
An interface system and a method therefor are disclosed for cooperating with a microprocessor based control system that presents at least one of a plurality of options for selection on a display. The system provides a first and a second rotatable dial each of which provide at least one of a plurality of inputs to the microprocessor controlled display. The combination of inputs from the first dial and the second dial define one or more menu-like options that a user can select from the display via a selection push button. A second push button is provided to enable the user to reject or step out of a menu option. This interface system, unlike keyboards and mouses, is particularly compact and rugged. Consequently, this interface system is exceptionally well suited for interacting with a microprocessor based control system in an industrial environment or any other type of harsh operating environment.
