Each BDM is in signal communication with the SHPD via a plurality of signal paths that are separate from the plurality of 1553 buses. The plurality of BDMs includes least two BDMs. The first and second BDMs are in signal communication with a first and second 1553 bus having a first security level and second security level, respectively, where the signal communication is only in a receive mode from the first and second 1553 buses to the two BDMs.
