Rapid reprogramming terminal

Abstract

A rapid reprogramming terminal (RRT) adapted for communication with military aircraft MIL-STD-1553 multiplex data bus which includes generally four avionics and one electronic warfare bus on board each aircraft. The RRT may be used to reprogram all electronic warfare and avionics systems aboard and aircraft including the bus controllers for each avionics or electronic warfare bus and the remote terminals connected to each bus. The RRT includes a high speed digital signal processor which executes functions required to reprogram a remote terminal or bus controller through software stored in an electrically erasable programmable read only memory (EEPROM). 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 RRT establishes communications with either an avionics bus or electronic warfare 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 serial format to an encoder/decoder which converts the digital data to Manchester encoded differential data for transfer via the MIL-STD-1553 multiplex data bus to the remote terminal or bus controller being reprogrammed. The present invention also provides for a verify operation whereby the data stored in the IC memory card is compared with the data in the bus controller or remote terminal being reprogrammed to verify that the data is identical.
