The remote telemetry unit effects a wireless transmission of a standard message structure containing the pressure and level data and the global position data. The security device is a separate hardware device from the data processing system. The fiber end portions are optionally disposed within a straight fiber guide at a coupler inputoutput end, which is preferably configured to have a standard connector geometry. Each actuator may have an address which is different from an address of the other actuators connected to the communications bus.
