1.1. System Overview
The EFD1000 Pro PFD system typically consists of
four components:
1. EFD1000 Display Unit
2. Conguration 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 EFD1000. In
some installations, generally when the aircraft is not
equipped with an autopilot and has only digital GPS/
nav/comms, the ACU may be omitted.
The system architecture in (Figure 1-5) shows the
relationships of the PFD, RSM, Conguration Module
and ACU.
