Functional Description

RMP--8A, 8B ARINC 429 Data Loader Input: [RMP--8A (A), RMP--8B (B)]

These pins are used when the T

CAS computer unit is communicating with an ARINC

603 or 615 airborne data loader (ADL) through the rear ARINC 600 connector. The data

loader programs the program memory in the T

CAS computer unit per the data loader

function specified. The ADL and portable data loader (PDL) Low Speed ARINC 429

inputs (12.5 kbits/s) have separate receiver busses to allow for simultaneous connection

of the ADL and PDL.

These pins are also connected to the front (PDL) connector on the front of the unit. See

J1--1 and J1--2.

RMP--9A, 9B ARINC 429 Data Loader Output: [RMP--9A (A), RMP--9B (B)]

These pins are used when the T

CAS computer unit is communicating with an ARINC

603 or 615 airborne data loader (ADL) through the rear ARINC 600 connector. This

connection is used to transmit data to the ADL during data loading operations.

These pins are also connected to the front (PDL) connector on the front of the unit. See

J1--8 and J1--9.
