A store interface for routing different types of store signal formats to multiple wing stations using pre-existing aircraft wing wiring. The store interface provides an interface between an aircraft and an associated store adapted to bidirectionally communicate with the aircraft according to one of a plurality of predetermined store signal formats. The store interface includes a store identifier that determines the type of the associated store, and an interface that bidirectionally communicates between the aircraft and the store, includinga first and second communication links that communicate with the store using either a first set of store control signals configured in accordance with a first store signal format or a second set of store control signals configured in accordance with a second store signal format. The store interface also includes a switch that couples one of the communication links to the store in response to the store identifier allowing one of the sets of store control signals to be transmitted between the aircraft and the store.
