Data downloading housing i.e. D-box for embedded aeronautical equipment, has software resources with physical definition of data transfer protocol, so as to ensure transfer of data to be downloaded according to data transfer protocol

摘要

The housing i.e. D-box has a CPU, an internal operating system (F04), an Ethernettype interface (F02) for downloading data, a storage unit (F08) for storing the data, and software resources (F10) with a physical definition of data transfer protocol. The software resources ensure the transfer of data to be downloaded according to the data transfer protocol, a universal serial businterface, and a transmission unit of the data to be downloaded. The data transfer protocol includes a cyclic redundancy check for allowing detection of data transmission errors.
