A garage door opener system having a garage door opener and a remote input device electrically connected to the garage door opener by an electrical conductor. The remote input device receives power by the electrical conductor. The remote input device includes a device controller to communicate an event message, monitor for an acknowledgement message within a time period, and repeat the event message when the acknowledgement message is not received within a time period. The garage door opener includes a master controller. The master controller receives the event message and communicates the acknowledgement message in response to receiving the event message. Also disclosed is a method of operating the garage door opener system.

The system of claim 1, wherein the remote input device includes a keypad having a button. 3. The system of claim 2, wherein the device controller monitors for an input from the button and communicates the event message in response to receiving the input. 4. The system of claim 3, wherein the device controller repeats the event message at a time period when the input is continuous for greater than the time period. 5. The system of claim 4, wherein the remote input device includes a second button, wherein the device controller monitors for a second input from the second button, communicates a second event message in response to the second input, monitors for a second acknowledgement message within a second time period, and repeats the second event message when the second acknowledgement message is not received within the second time period. 6. The system of claim 5, wherein the master controller receives the second event message, and communicates the second acknowledgement message in response to receiving the second event message. 7. The system of claim 3, wherein the device controller communicates a heartbeat message when the input is not received within a second time period. 8. The system of claim 7, wherein the device controller repeats the heartbeat message when the input is further not received within a third time period, the second and third time periods being the same length of time. 9. The system of claim 1, wherein the system further comprises a terminal supported by the structure, wherein the structure includes a housing enclosing the motor, power supply, and controller, wherein the remote input device is external to the housing, and wherein the system further comprises the electrical conductor for connecting the remote input device to the terminal. 10. The system of claim 1, wherein the event message is one of a key press message and a key hold message. 11. The system of claim 1, wherein the remote input device includes a light-emitting diode, and wherein the acknowledgement message includes a value for controlling the light-emitting diode. 12. The system of claim 1, wherein the control of the power to the motor is based on the received event message. 13. A method of operating a garage door opener system including a garage door opener and a remote input device electrically connected to the garage door opener, the method comprising: receiving a power from the garage door opener at the remote input device over the electrical conductor;communicating an event message over the electrical conductor from the remote input device;receiving the event message at the garage door opener;communicating an acknowledgement message in response to receiving the event message;monitoring for the acknowledgement message within a time period at the remote input device;repeating the event message when the acknowledgement message is not received within the time period; andcontrolling a power of the garage door opener for moving a garage door. 14. The method of claim 13, wherein the remote input device includes a keypad having a button, and wherein the method further comprises receiving an input from the button, and wherein the communicates the event message is in response to the receiving for the input. 15. The method of claim 14, and further comprising repeating the event message at a time period when the input is continuous for greater than the time period. 16. The method of claim 14, and further comprising communicating a heartbeat message when the input is not received within a second time period. 17. The method of claim 16, and further comprising repeating the heartbeat message when the input is further not received within a third time period, the second and third time periods being the same length of time. 18. The system of claim 1, wherein the event message is one of a key press message and a key hold message. 19. The method of claim 13, and further comprising controlling a light-emitting diode of the remote input device based on the acknowledgement message. 20. The method of claim 13, wherein the controlling the power of the garage door opener is based on the event message.
