Abstract : This report describes a rapid reprogramming terminal for reprogramming all electronic warfare and avionics systems aboard an aircraft including the bus controllers for each avionics or electronic warfare bus on the MS-1553 multiplex data bus in the aircraft and the remote terminals connected to each bus in the aircraft. The rapid reprogramming terminal includes a high speed digital signal processor which executes the functions required to reprogram a remote terminal or bus controller through software stored in an electrically erasable program read only memory. The information required to reprogram a remote terminal or bus controller is stored on an IC memory card which is electrically coupled to the digital signal processor. When the rapid reprogramming terminal establishes communications with either an avionics bus or electronic warfare bus by enabling certain discretes associated with the bus, the digital data required to reprogram, for example, a remote terminal is transferred from the IC memory card through the digital signal processor in a parallel format to a 1553 communications interface controller. The controller converts the digital data to Manchester encoded differential data for transfer via the MS-1553 multiplex data bus to the remote terminal or bus controller being reprogrammed.
