Abstract

A setup and calibration unit for a barrier operator is operable to communicate with the operator'"'"'s own controller. The calibration unit includes a control circuit connected to a visual display and to a set of switches controlled by switch actuators for placing the operator controller in a controller run mode or calibration mode, scrolling through selected actions displayed on the display in one direction or the other, a set/clear function and display backlighting for user interaction with the setup and calibration unit. The setup and calibration unit is particularly adapted for use with upward acting sectional and roll-up doors and other types of barriers movable between open and closed positions by motorized operators. The calibration unit may be operably connected to the operator controller via hard wiring, a radio frequency link or an infrared or visible light transmission link.
