The system's Engine Interface Unit (EIU) is mounted on the engine-side of the firewall. All engine sensors connect directly to the EIU. The engine data is communicated on a true aerospace network via a CAN bus to the Display Unit (DU).
From the EIU, the supplied communications cable connects to a single bulkhead connector at the firewall. A second supplied communications cable is connected from the firewall to the DU. This networked system reduces wire runs, thereby significantly reducing installation costs and is very advantageous for pressurized aircraft. The AuRACLE networked system architecture is also ideal for aircraft when the engine is far from the cockpit.
