Operator with transmitter storage overwrite protection and method of use
First Claim
1. An operator with transmitter overwrite protection, comprising:
- a plurality of different transmitters, each of said different transmitters having at least one function button that when actuated generates a signal which includes at least a transmitter identifying code and wherein one of said different transmitters has at least one critical function button;
a receiver capable of receiving said signal from any of said plurality of different transmitters;
a memory comprising a plurality of storage locations; and
a controller connected to said receiver, said controller storing each said transmitter identifying code in a corresponding one of said plurality of storage locations, said controller overwriting one of said transmitter identifying codes in a corresponding one of said plurality of storage locations when a new transmitter identifying code is learned if said plurality of storage locations are full, except for said transmitter identifying codes in said plurality of storage locations for one of said plurality of different transmitters that has said critical function button.

Abstract
An operator (32) with transmitter overwrite protection is used with a plurality of different transmitters (40, 42, 44). Each type of transmitter has at least one command button that when actuated generates a signal which includes at least a transmitter identifying code. The operator includes a receiver (170) capable of receiving the signal from any of the plurality of transmitters and a memory device (62) that has a plurality of storage locations (63a-f). A controller (60) is connected to the receiver and the controller stores each transmitter identifying code in a corresponding storage location. The controller overwrites one of the transmitter identifying codes in a corresponding storage location when a new transmitting code is learned if the plurality of storage locations are full, except for the transmitter identifying codes for one specific type of the plurality of transmitters. In the preferred embodiment, the specific type of transmitter is a wall station transmitter (42) with more than one function button. The different types of transmitters may be provided with corresponding levels of overwrite priority.

8. A method for protecting transmitter codes stored by a movable barrier operator, comprising
providing in the operator a controller with a receiver capable of receiving signal transmissions; -
providing a memory device connected to said controller, said memory device having a plurality of storage locations;
learning any one of a plurality of different transmitters each of which has a transmitter identifying code contained in said signal, wherein one of said plurality of different transmitters is a wall station transmitter which has a wall station transmitter identifying code;
storing each said transmitter identifying code in a corresponding one of said plurality of storage locations and storing said wall station transmitter identifying code with overwrite protection; and
overwriting one of said plurality of storage locations with a new transmitter identifying code if all said plurality of storage locations are full when a new transmitter is learned, except for those plurality of storage locations storing transmitter identifying codes with overwrite protection. - View Dependent Claims (9, 10, 11, 12)

13. A movable barrier operator system, comprising:
-
a plurality of transmitters enabled to operate a movable barrier each said transmitter having a transmitter identifying code, wherein certain ones of said transmitter identifying codes have priority over other ones of said transmitter identifying codes, wherein said plurality of transmitters are selected from the group consisting of a wall station transmitter, a keypad transmitter and a portable transmitter; and
a controller having a memory device with a plurality of storage locations, said controller receiving and storing said transmitter identifying codes in said storage locations, wherein priority transmitter identifying codes of said wall station transmitter are never overwritten by other transmitter identifying codes. - View Dependent Claims (14, 15, 16, 17, 18)
