ABSTRACT:
A digital radio control system comprising a transmitter and receiver wherein a plurality of two position switches may be set in a transmitter to pick a particular code which will be serially transmitted by the transmitter and in which a plurality of switches in a receiver may be set to a particular code such that if the same code is selected in the receiver as is set in the transmitter the receiver will be energized upon recognition of the code. Such transmitters and receivers are adaptable to many applications, as for example, garage door actuators; and due to the large number of possible code combinations, interference between other control units within radio frequency range will not occur.
