NOTE
The EFD500 MFD does not oer Autopilot or
DecisionHeight.
1.1.4. Conguration Module (CM)
The Conguration Module contains an EEPROM device that retains system
conguration and calibration data and provides two primary functions (Figure 1-7):
• Retains aircraft-specic conguration information, calibration data, and pilot
settings, allowing the PFD to be swapped for service purposes without re-entering
or re-calibrating the installation.
• Contains a license key that congures the EFD system software features.
The CM is typically attached to the wire bundle coming out of the D-sub connector on
the system unit.
1.1.5. Analog Converter Unit (ACU) - optional
The optional ACU enables the all-digital EFD1000/500 system to interface to analog
avionics when required. The ACU converts multiple analog interfaces to the digital
ARINC 429 buses supported by both the EFD1000/500 displays. Control parameters,
such as desired heading, are also sent from the EFD to the ACU for conversion to analog
format for autopilot support. The ACU is required when any of the following capabilities
are required (Figure 1-8):
• Interface to supported autopilots.
• Interface to conventional VHF navigation radios.
• Interface to legacy (non-ARINC 429) GPS navigators.
• Interface to supported radar altimeter decision height annunciations.
If ARINC 429-based digital radios, such as the Garmin 400/500-series GPS/nav/comm
radios, are installed in the aircraft, and no other aircraft interfaces are desired, the ACU is
not required.
