Abstract: A digital communication network adapts a conventional MIL-STD-1553 aircraft multiple weapons rack for carriage of smart weapons. The network is a communications, power, and signal management interface circuit which permits an existing single pylon wing RT/sub-bus to control a plurality of additional smart RT's. The network utilizes a sub-bus which includes an RT and a bus controller for the multiple stores. The output of the RT/sub-bus is divided to create a plurality of inputs to the additional RT's to establish a power and communications link with the aircraft controller. The network includes a processor which receives coded digital communications from the controller and selectively rebroadcasts those communications to one of the smart weapons on the rack designated by the coded communication.
