Functional Description
RMP−6E 2000 FT Altitude Limit Program Pin (NO)
This pin, along with pins RMP−6F thru RMP−6J, select the “can’t climb” altitude in
2,000−foot 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 (RMP−6K).
RMP−6F 4000 FT Altitude Limit Program Pin (NO)

RMP−6G 8000 FT Altitude Limit Program Pin (NO)

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 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
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/RA Display No. 1 Status Discrete Input (NO)
Two display status discrete inputs are provided by the TCAS computer unit at RMP−7E
(TA/RA Display No. 1) and RMP−7J (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.
