Abstract: A method and decoder-based irrigation controller, and method and programming chart, are provided. In some embodiments, a decoder-based irrigation controller comprises a microcontroller; and a first connector coupled to the microcontroller and configured to couple to a reader, wherein the reader comprises an optical reader configured to read an optically readable pattern, wherein the first connector is further configured to couple an input from the reader to the microcontroller; and wherein the microcontroller is configured to interpret the input from the reader and perform an action at the decoder-based irrigation controller according to the input.

Abstract: A method and programming chart having viewable indicia thereon for programming a decoder-based controller is disclosed. The programming chart comprises a specific portion comprising a station number area for one or more stations being controlled by a decoder-based irrigation controller, a decoder address area adapted to receive an entry indicating an address of a decoder being associated with each of the one or more stations and a plurality of other information areas for each of the one or more stations to receive information pertaining to each of the one or more stations. Furthermore, a method is provided for programming a decoder-based irrigation controller comprising associating a decoder unit with at least a first station, removing a decoder address indicator provided with the decoder unit and recording the decoder address indicator onto a programming chart onto an area designated for a decoder address associated with the first station.
