A first backplane for being electrically coupled to a second backplane, a system monitoring module, and at least one transducer monitoring module includes a system interface bus configured to be coupled to the system monitoring module and the second backplane. The intermediate backplane also includes at least one monitor interface bus configured to be coupled to the at least one transducer monitoring module and the second backplane and an intermediate backplane bus configured to be coupled to the at least one transducer monitoring module and the system monitoring module.
