1. A control system, comprising:
- a controller having an output signal composed of a plurality of channels transmitted repeatedly in sequence, in a set period, an amplitude level of each channel being set independently of the other channels;
a plurality of addressable control devices, each addressable control device being connected to the controller and corresponding to at least one of the channels, each addressable control device having a changeable electronic address, switch means for switching between a program mode and an operation mode a plurality of times for remotely changing the address of each addressable control device a plurality gf times, each addressable control device being in its program mode when its address is changed, and receiving means for receiving the output signal of the controller, the electronic address of each addressable control device being set by the output signal when the addressable control device is in the program mode, the amplitude level for one of the channels of the output signal, corresponding to an addressable control device which is in its program mode, having its address being set non-zero, while the amplitude level for the channels corresponding to the other addressable control devices is zero.

Abstract
An addressable lighting device and control system uses a DMX protocol controller to selectively generate an electronic address for the addressable lighting device on which the device will respond to all future signals from the controller corresponding to that electronic address. The addressable device has a program mode for setting the address and a working mode for receiving control signals on the set address. The addressable device may have the address set and changed remotely using the DMX protocol controller and a remote control to switch modes, thereby avoiding the problems associated with using DIP switches to set device electronic addresses.
