Functional Description
RMP6E 2000 FT Altitude Limit Program Pin (NO)
This pin, along with pins RMP6F thru RMP6J, select the “can’t climb” altitude in
2,000foot increments up to 62,000 feet. This is the altitude the aircraft is not able to
achieve a 0.25 G vertical acceleration to a 1500 FPM climb rate for an altitude gain of 750
feet above a certain altitude under all circumstances. The “can’t climb” altitude is
selected by connecting jumper wires from altitude limit program pins to the program
common pin (RMP6K).
RMP6F 4000 FT Altitude Limit Program Pin (NO)
See RMP6E.
RMP6G 8000 FT Altitude Limit Program Pin (NO)

RMP6H 16000 FT Altitude Limit Program Pin (NO)
See RMP6E.
RMP6J 32000 FT Altitude Limit Program Pin (NO)

RMP7C, 7D ARINC 429 TA/RA Display No. 1 Output: [RMP7C (A), RMP7D (B)]
This is one of two ARINC 429 high speed bus outputs that supplies data to the TA/RA
display such as a VSI/TRA or EFIS. The other output (TA/RA Display No. 2) is at
RMP7G 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 J133 and J134.
RMP7E TA/RA Display No. 1 Status Discrete Input (NO)
Two display status discrete inputs are provided by the TCAS computer unit at RMP7E
(TA/RA Display No. 1) and RMP7J (TA/RA Display No. 2). A ground on either of these
inputs 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.
