ABSTRACT:
An all-trinary rolling code method and system which allow a barrier opener to generate and transmit trinary rolling codes without entering or storing any rolling code values as binary words includes obtaining a stored trinary counter value upon a transmitter being actuated to remotely control a barrier. A trinary function void of trinary to binary or binary to trinary conversions is used to transform the trinary counter value to a trinary rolling code output such that the trinary rolling code output represents a trinary value that would be produced if the trinary counter value were converted to binary, mirrored, had its highest ordered bit set to zero after being mirrored, and converted back to trinary. The trinary rolling code output is combined with a stored trinary transmitter identification value to generate a trinary word. The transmitter transmits the trinary word for receipt by a receiver associated with the barrier.
