(1)
Description and generation of aircraft configuration labels The aircraft configuration labels 155 and 156 are generated either from pin programming directly wired to the CFDIU or from data transmitted by the bus of other computers connected to the CFDIU.
(2)
Acquisition of labels making up the aircraft configuration labels. The configuration is memorized by the CFDIU 45 seconds after power-up tests and on maintenance phase NULL/DC2 transition. In the event of incorrect data at CFDIU input (labels not refreshed or SSM invalid), the CFDIU remains in the previous configuration. If the CFDIU detects a memory fault, it assigns the "present" default code to all systems on labels 155 and 156.

G. Pin Programming Function
The CFDIU generates and transmits on its output bus 2 aircraft configuration labels which contain pin programming of the electronic items of equipment which are optional on the aircraft. These configuration labels (155, 156 and 157) are used by all BITEs to know the printer status (installed or not installed) and by some systems (e.g: RMP) to know the status of some optional items of equipment (e.g: VHF3, HF2...).

H. Warning/Fault Messages Filtering Function
(1)
Principle
The purpose of this function is to improve the operational use of the POST FLIGHT REPORT, LAST LEG ECAM REPORT and LAST LEG REPORT printed at the end of the flight as well as the real-time fault and warning information transmitted by the ACARS, by filtering all the spurious or unjustified faults/warnings.
(2)
Operation
-The filtering function applicable to the generation of the POST FLIGHT REPORT and flight reports during their ACARS/printer transmission, can be de-activated through the MCDU.
R - The filter criteria can be uploaded by means of the portable data R loader or the MDDU (option).
