Functional Description
RMP-7A, 7B
ARINC 429 Air Data/Inertial Reference Unit (ADIRU) #1 (Left), Inertial
Reference Part (IRS) Input: [RMP-7A (A), RMP-7B (B)]
This high-speed input is provided for applications to receive Inertial Reference
System information.
RMP-7C, 7D
ARINC 429 TA/RA Display No.1 Output: [RMP-7C (A), RMP-7D (B)]
This is one of two ARINC 429 high-speed (100k bits/s) bus outputs that supply data
to the TA/RA display such as a VSI/TRA or EFIS. The other output (TA/RA Display
No.2) is at RMP-7G and -7H. The TA/RA Display No.1 outputs are also connected
to the front (PDL) connector, which is used to supply display information to
maintenance displays.
See J1-33 and J1-34.
RMP-7E
TA Display No.1 Status Discrete Input (NO)
Two display status ground/open discrete inputs (Note 1) are provided by the T

CAS
computer unit at RMP-7E (TA/RA Display No.1) and RMP-7J (TA/RA Display No.2).
If a display provides a ground on either of these inputs, it is interpreted by TCAS to
mean the display associated with that input is operating normally and is capable of
displaying the TA/RA information, and that its data bus is active. An open indicates
the inability of the display to present advisories or indicates its data bus is inactive.
RMP-7F
FMC 1 or 2 Selected
This input controls the selection between FMC 1 or FMC 2 as the active source of
FMC data.
RMP-7G, 7H
ARINC 429 TA/RA Display No.2 Output: [RMP-7G (A), RMP-7H (B)]
See RMP-7C and -7D.
RMP-7J
TA Display No.2 Status Discrete Input (NO)
See RMP-7E.
RMP-7K
FMC GNSS 1 or 2 Selected
This input controls the selection between FMC GNSS 1 or 2 as the active source of
FMC GNSS data.
