Remote Control Technology 01381-001-001 DCI-1 Interface Cable connects internally to Irritrol®, Superior® and Hit® Logic Irrigation controllers. A DCI paired with a Universal Commander or Sidekick system converts the control logic of the Universal Receiver to match the control logic of the controller. This expands the capability of the Commander or Sidekick to operate as many stations as the controller has available, rather than the limitations of 12, 24, and 32 stations.
