A method and system for detecting faults in a communication interface is disclosed. The communication interface is connected to a field device and a device bus comprising generating periodic diagnostic pulse by a programing unit. The programming unit is communicatively connected to the controller and a controller interface and provides the diagnostic pulse to a multiplexer to periodically apply the diagnostic pulses from the programming unit to a first winding of a transformer. The programming unit provides the diagnostic pulse to the isolation unit. A sensing unit senses a voltage drop across a sense resistor, the sensing unit having an input connected to the sense resistor and an output connected to the programming unit. The sensing unit communicates a sense signal based on the comparison to the programming unit, and switches from a primary or a secondary module to the other based on the sense signal.

A meter case used with a utility meter is disclosed. The meter shell includes a plurality of snap fit joints assembled on the meter case arranged to engage a module cover to mount the module cover to the meter shell. The module cover further includes wire housing formed along an inner periphery of the module cover that houses a wire having a first end and a second end therein. A metal shield placed behind the meter shell is electrically coupled to a first connector. A terminal electrically connected to the metal shield is arranged to discharge current to ground. An electrical contact electrically coupled to the second end of the wire is arranged to engage the first connector to establish an electrical connection to the metal shield for the discharge to ground of electrostatic currents sensed by wire.
