RMP−15J, 15K ARINC 429 TX Coordination No. 1 Output: [RMP−15J (A), RMP−15K (B)]
This differential pair output is a high speed ARINC 429 bus (100K bits/second nominal),
that transmits data from the TCAS computer unit to the No. 1 Mode S Transponder.
The labels on this bus are as follows: 273, 274, 275.

RBP−1H RA Data Word 270 Bit 18 Discrete Output
This discrete output provides RA information to the ARINC 573 flight recorder. The
output goes to the “ground” state each time its associated bit within the advisory field of
the RA output words changes from a “zero” condition to a “one” condition. The output
remains in the “ground” state for as long as the associated RA bit remains non−zero.
This output is read by the flight recorder as either a series or shunt output.
