Abstract
A controller for a door operator including a processor, a first actuator, and a transmitter, and associated method. The method may include inverting bit positions of a rolling code, dividing the inverted code by a predetermined number, converting the divided inverted code to base 9 coefficients, and substituting an output nibble for each base 9 coefficient in the divided converted code. The transmitter may be configured to transmit the substituted output nibble responsive to actuation of the first actuator.
