Patent abstract
A barrier operator system is disclosed that is capable of receiving different wireless signals. The system includes a primary controller that is connected to a first receiver which receives a first wireless signal. And the system includes a second receiver circuit that is connected to the controller and receives a second wireless signal that is different from the first wireless signal. This allows the system to accept wireless signals from two or more different types of transmitters to allow for use of older technology transmitters with newer technology operator systems. The wireless signals may be in the form of radio frequency, infra-red, visible light or audio signals.
