Apparatus and method for establishing a radio frequency communications link between a controller and a remote controllable system
First Claim
1. A radio frequency data link to establish communications between a controller and a remote controllable system, comprising:
- interface means for producing command signals indicative of desired system functions;
transmitting RF means for receiving the command signals and responsively generating radio frequency signals representative of the command signals, the transmitting RF means including an RF modem having a serial number;
a remote controllable system, including;
a switch being selectable to a plurality of positions, each switch position representing a predetermined ID number that identifies the remote controllable system;
receiving RF means for receiving the radio frequency signals and responsively converting the radio frequency signals into control signals, the receiving RF means including an RF modem having a serial number, wherein the radio frequency signals include information representing the serial number of the transmitting RF modem and the predetermined ID number associated with the receiving remote controllable system; and
logic means for receiving the control signals, performing the desired function, and producing a reply signal that indicates the serial number of the receiving RF modem to establish point-to-point communication between the transmitting and receiving RF modem pair.

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.
