1.1. System Overview
The PFD system typically consists of four components:
1. EFD 1000 Display Unit (PFD)
2. Conguration Module (CM)
3. Remote Sensor Module (RSM)
4. Analog Converter Unit (ACU)

The ACU converts older analog signals and interfaces to the
industry-standard digital ARINC 429 interface, which is the
native language of the PFD. In some installations, generally
when the aircraft is not equipped with an autopilot and has
only digital GPS/Nav/Comm, the ACU may be omitted.
The system architecture in Figure 1-5 shows the relationships
of the PFD, RSM, CM and ACU.
