Abstract
An encrypted rolling code, a plurality of differing data bit order patterns, and a plurality of differing data inversion patterns are provided. Based on the encrypted rolling code, patterns are selected from one or more of the plurality of differing data bit order patterns and the plurality of differing data inversion patterns. At least a part of the encrypted rolling code is transmitted to a movable barrier operator using the selected patterns as transmission characteristics.
