A Kitchen Display System (KDS) Controller is a Windows service that controls KDS Displays and performs other KDS-related functions. KDS Controllers move data to and from the KDS Displays. When an order is placed on a workstation, the KDS Controller routes the order to the appropriate KDS Display(s). When an order is bumped from a KDS Display, the KDS Controller routes the information about the order to the reporting database. Updates to KDS Displays (changing a Tool Bar or Bump Bar button) are routed through the KDS Controller.
