Abstract
A method of coding to provide command signals simultaneously to selected devices is disclosed. Each device is assigned a different power of the same integer. Commands are then signaled to the desired devices by sending a series of pulses, the total of which is the sum of the integer raised to the power of each the devices to be commanded. Thus if devices having powers of 0 and 3 are to be commanded, and the integer is 2, 9 pulses would be sent. (2.degree.=1, 2.sup.3 =8, 1+8=9). Each different total will signal a unique device or a unique combination of devices.
