(4) When the AES ID Bus is ORTenabled, there is no requirement for the SDU to process
Labels 150 (Time) and 260 (Date).
E. MCDU Interface
(1) The ACD:
(a) Sets each of the three ARINC 429 MCDU receive interfaces, "Data from MCDU
1", "Data from MCDU 2", and "Data from MCDU 3", which are activated by the
ORT to low speed.
(b) Disables each of the three ARINC 429 MCDU receive interfaces, "Data from
MCDU 1", "Data from MCDU 2", and/or "Data from MCDU 3", when disabled by
the ORT.
(c) Transmits on the ARINC 429 "Data to MCDU 1,2,3" interface using the following
System Address Labels in Subsystem Identifier Messages:
1 307o when configured as SDU 1; OR
2 173o when configured as SDU 2.
NOTE: The SDU number is determined by configuration pin #5
(config. input pin TP04D).
(2) The ACD transmits the Equipment ID Label 377 on the ARINC 429 "Data to MCDU 1,2,3"
interface with a period of 1 s ± 100 ms and an SDU Equipment ID encoded as 41 BCD.
