Figure 1 Mark III CMU Front Panel

ARINC 607 defines the Aircraft Personality Module (APM) which contains all aircraft and system configuration information. The APM is external to the MARK III CMU and is a permanent fixture in the aircraft. Only one APM is required per MARK III CMU installation (one APM for each MARK III CMU mounting tray). The same APM part number is used on all aircraft in the fleet.

2.2 System Interfaces

The Mark III CMU supports an extensive set of interfaces. Many of these interfaces are specifically defined by ARINC 758. There are also a number of spare ARINC 429 ports available for additional devices as needed by the user. The Mark III CMU supports all of today’s ACARS interfaces used on today’s aircraft, with extensive capability for future growth.
