ABSTRACT:
A radio frequency data link that establishes communications between a controller and a remote controllable system is disclosed. The controller includes an interface device that produces command signals indicative of desired system functions. A transmitting RF modem receives the command signals and responsively generates radio frequency signals that are representative of the command signals. A remote controllable system includes a receiving RF modem that receives the radio frequency signals and responsively converts the signals into control signals. A logic device receives the control signals, performs the desired function, and produces a reply signal that indicates the status of the function.
