Abstract

The present invention provides a method of restoring a remotely-located control device of a wireless load control system to a default factory setting. The control device is operable to be coupled to a source of power and has a memory for storing programming information. First, a beacon message is transmitted repeatedly on a predetermined channel. Second, power is applied to the control device. Subsequently, the control device listens for the beacon message for a predetermined amount of time on each of the plurality of channels, and receives the beacon message on the predetermined channel. Next, the a first signal uniquely identifying the control device is transmitted wirelessly from the control device on the predetermined channel within a predetermined amount of time power is applied to the control device. Finally, the control device receives a second signal transmitted on the predetermined channel, and programs the memory with the default factory setting in response to the second signal.

Claims

1. A method for restoring a first radio frequency (RF) control device of a plurality of control devices from a first state to a second state, the plurality of control devices operable to be controlled by radio frequency signals transmitted on one of a plurality of radio frequency channels by a first transmitter device, the first RF control device adapted to be coupled to a source of power, a switch coupled in series between the source of power and the control device, the method comprising the steps of:

initiating at the first transmitter device an out-of-box mode to configure the first RF control device into the second state;

transmitting a beacon message on one of the channels from the first transmitting device in response to the step of initiating at the first transmitter device the out-of-box mode to configure the first RF control device into the second state;

subsequently operating the switch to cycle power to the first RF control device from off to on to identify the first RF control device as requiring an address;

monitoring by the first RF control device for the beacon message that is transmitted on one of a plurality of radio frequency channels, wherein the first RF control device begins to scan on each of the plurality of radio frequency channels each for a period of time for the beacon message, and wherein the first RF control device locks on to the one of the plurality of channels on which the beacon message is received and then halts further scanning;

transmitting by the first transmitter device an instruction message to the first RF control device that instructs the first RF control device to receive the messages transmitted on a designated radio frequency channel;

determining at the first transmitter device the presence of the first RF control device;

enabling a user to select at the first transmitter device the first RF control device for restoration to the second state; and

transmitting a message on the designated radio frequency channel from the first transmitter device, while the first transmitter device is in the out-of-box mode, to be received by the first RF control device to restore the first RF control device to the second state.

2. The method of claim 1, wherein the second state is a default state whereby the control device is configured with factory default settings.

3. The method of claim 1, wherein the step of determining comprises:

determining at least one unique identifier for the first RF control device; and

compiling a list at the first transmitter device including the at least one unique identifier.

4. The method of claim 3, wherein the step of determining further comprises:

transmitting from the first transmitter device to the plurality of control devices a clear signal to clear a second flag in a memory of each control device;

responding by each control device to the clear signal only if a first flag in memory of the control device has been set corresponding to a requirement to obtain an address;

transmitting a polling signal to the control devices from the first transmitter device;

providing by the control devices an acknowledgment signal to the first transmitter device that the second flag is cleared;

storing information related to the acknowledgment signal in a memory of the first transmitter device;

transmitting from the first transmitter device a further signal to each control device from which an acknowledgment signal was received by the first transmitter device to obtain the unique identifier of the control device;

transmitting by the control device the unique identifier to the first transmitter device; and

transmitting by the first transmitter device a signal to the remote control device whose unique identifier has been received at the first transmitter device to set the second flag in the memory of the remote control device.

5. The method of claim 4, further comprising manually activating a control on the first RF control device to set the first flag and identify that the first RF control device requires an address.

6. The method of claim 4, wherein the first flag is set by operating the switch to cycle power to the first RF control device from off to on to identify the first RF control device as requiring an address.

7. The method of claim 4, wherein the first flag is set by a user providing a unique identifier of the first RF control device to identify the first RF control device as requiring an address.

8. The method of claim 3, wherein the unique identifier comprises a manufacturer serial number of the control device.

9. A method of restoring a remotely-located control device of a control system to a default factory setting, the control device operable to be coupled to a source of power, a switch coupled in series between the source of power and the control device, and having a memory for storing programming information, the method comprising the steps of:

transmitting a beacon signal on a predetermined channel;

subsequently operating the switch to cycle power from off to on to the control device in response to the step of transmitting a beacon signal on the predetermined channel;

the control device subsequently listening for the beacon signal for a predetermined amount of time on each of a plurality of channels in response to the step of subsequently operating the switch to cycle power from off to on to the control device;

the control device receiving the beacon signal on the predetermined channel within the predetermined amount of time;

the control device transmitting on the predetermined channel a first signal uniquely identifying the control device within the predetermined amount of time after the step of operating the switch to cycle power from off to on to the control device;

the control device receiving a second signal transmitted on the predetermined channel in response to transmitting on the predetermined channel the first signal uniquely identifying the control device; and

the control device programming the memory with the default factory setting in response to the second signal.

10. The method of claim 9, wherein the step of transmitting a beacon signal comprises transmitting a beacon message repeatedly on the predetermined channel.

11. The method of claim 9, wherein the control system comprises a wireless control system.
