Method and apparatus for a rolling code learning transmitter
First Claim
1. A method of learning valid security codes by a security code receiver, comprising steps of:
- receiving a first security code from a first transmitter;
within a predetermined period of time receiving from a second transmitter a second security code, having a predetermined relationship to the first security code from the first transmitter;
confirming the predetermined relationship by comparing the first security code and the second security code;
in response to confirming the predetermined relationship, storing a representation of the second security code as a valid security code.

Abstract
A barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code type access codes; at least one trained transmitter for operating the system by transmitting a rolling code type access code to the receiver; at least one learning transmitter for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller for evaluating the relationship between the learning transmitter rolling type access code and the trained transmitter rolling type access code; and a device for providing a barrier movement in response to access codes received by the receiver. The barrier movement operator provides a method of learning valid security codes by a security code receiver comprising the steps of receiving a first security code, then within a predetermined period of time receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code.

4. A method of learning valid security codes by a security code receiver, comprising steps of:
-
receiving a first security code from a first transmitter; within a predetermined period of time, receiving from a second transmitter a second security code having a predetermined relationship that correlates to the first security code from the first transmitter in a defined manner, and storing a representation of the second security code as a valid security code; wherein the predetermined relationship comprises a correlation between the first security code and the second security code; and wherein the correlation comprises, at least in part, that a rolling code access code portion of the second security code is next in a sequence as determined with respect to a rolling code access code portion of the first security code. - View Dependent Claims (5, 6, 7)

8. A method of training a security code transmitter to operate with a security code receiver, comprising, at the security code transmitter to be trained:
-
receiving at the security code transmitter from an already-trained security code transmitter a security code transmission comprising, at least in part, a fixed identification portion and a rolling code portion; determining a valid subsequent rolling code portion based upon the rolling code portion; transmitting to the security code receiver the fixed identification portion and the valid subsequent rolling code portion. - View Dependent Claims (9, 10, 11, 12)
