Abstract
An automatic meter reading system that includes a head end controller and an endpoint that is interfaced to a utility meter. The head end controller and the endpoint communicate via RF communication. The endpoint includes an internal clock that synchronizes itself to a clock countdown signal. The clock countdown signal is generated by the head end controller through use of sequence inversion keying.
