The AIMS cabinets transmit data to the channel A, the channel B, and the channel C EDIU interface cards, in each EDIU.
The AIMS cabinets transmit data to the EDIUs on the same systems ARINC 629 buses that they receive data from. The EDIUs then transmit the data received from the AIMS cabinets to the left and right EECs.
APU Controller
The AIMS cabinets receive APU data from the APUC controller on the left and right systems ARINC 629 buses.
The AIMS cabinets transmit data to the APU controller on the left and right systems ARINC 629 buses.
FQPU
The AIMS cabinets receive fuel data and system status data from the FQPU on the left and right systems ARINC 629 buses.
The AIMS cabinets transmit data to the FQPU on the left and right systems ARINC 629 buses.
AMU
The AIMS cabinets receive digital audio system status data from the AMU on the left systems ARINC 629 bus.

CDU
The AIMS cabinets receive keyboard selection data and map data from the left, right and center CDUs on the left and right systems ARINC 629 buses.
The AIMS cabinets transmit data to the CDUs on the left and right systems ARINC 629 buses.
AFDC
The AIMS cabinets receive autopilot status and guidance data from the left, right and center AFDCs on the left, right and center 1 systems ARINC 629 data buses.

AIMS -AIMS INTERCABINET ARINC 629 BUSES INTERFACES
General
The left and right AIMS cabinets transmit and receive data on all
four of the AIMS communicate with intercabinet (IC) 2 bus. intercabinet the AIMS (IC) cabin buses. ets on The the CDUs AIMS
AIMS Cabinets
Data that goes between the two AIMS cabinets includes intra-function active-nonactive data and inter-function communication data.
CDU
If the systems ARINC 629 buses fail, the CDUs use the AIMS IC 2 bus. The AIMS cabinets receive keyboard selection data and map data from the left, right and center CDUs on the IC 2 bus.

AIMS -ARINC 429 INPUTS INTERFACES
General
These are the four ways the ARINC 429 input buses go to the input/output modules:
*
ARINC 429 bus goes directly to one IOM
*
ARINC 429 bus goes to two IOMs in the same AIMS cabinet
*
ARINC 429 bus goes to one IOM in each AIMS cabinet.
*
ARINC 429 bus goes to two IOMs in each AIMS cabinets.
More critical systems usually send their data to more that one IOM.
The ARINC 429 buses may be either low speed or high speed buses.
ARINC 429 inputs
These LRUs send data to the AIMS cabinet on ARINC 429 buses:
*
Autothrottle servo motors
*
Mode control panel
*
VHF communication transcievers
*
HF communication transceivers
*
Radio tuning panels
*
Satellite data unit
*
Clocks
*
Cursor control devices (Capt and F/O)
