B. Output Interface
(1) Digital Outputs The radio-communication and radio-navigation equipment receives the frequency and course data through words. These words have a structure and a refresh rate defined in ARINC 429 Characteristics. On the COM bus 1, each RMP transmits the labels 030, 037, 040, 047, 356, 377. On the COM bus 2, each RMP transmits the labels 030, 037, 040, 047,
377.
On the NAV bus, each RMP transmits the labels 034, 035, 024, 100,
033, 017, 105, 032 and 377.
The table below contains the characteristics of all these parameters:

8. Test
____
A. Built-In Test Equipment (BITE) The BITE facilitates maintenance on in-service aircraft. It detects and identifies a failure related to the RMP. The BITE of the RMP is connected to the Centralized Fault Display Interface Unit (CFDIU) (Ref. 31-32). The BITE:
-Transmits permanently RMP status and its identification message to the CFDIU.
-Memorizes the failures which occurred during the last 63 flight segments.
-Monitors data inputs from the various peripherals (VHF, HF and CFDIU).
-Transmits to the CFDIU the result of the tests performed and self-tests.
-Can communicate with the CFDIU through the menus.
B. General Operation
The BITE can operate in two modes:
-
The normal mode
-
The menu mode.
(1)
Normal mode In normal mode the BITE monitors cyclically the momentaneous status of the RMP. It transmits these information signals to the CFDIU during the concerned flight. In case of fault detection, the BITE stores the information signals in the fault memories. These information signals are transmitted to the CFDIU every 100 ms by an ARINC 429 message with label 356, and label 377 with equipment id:36.
(2)
Menu mode The menu mode can only be activated on the ground. This mode enables communication between the CFDIU and the RMP BITE by means of the Multipurpose Control and Display Unit (MCDU).

The RMP menu mode is composed of:
-LAST LEG REPORT
-PREVIOUS LEGS REPORT
-LRU IDENTIFICATION
-TROUBLE SHOOTING DATA
-TEST.
