 RS-232/422 Serial Ports (4)
These interfaces can be software-configured to connect to different aircraft systems. Typical
interfaced systems include EFB, Global Positioning System (GPS), etc.
 Ethernet Ports (4)
These interfaces can be used to connect to several different systems. Typical interfaced systems
include EFB, CFDS, etc. One of these ports can also be used to provide a remote maintenance
port interface (e.g. in the flight compartment).
 Discrete Outputs (8) and Inputs (16)
Discrete inputs and outputs can be used to provide or supplement various flight crew control and
display interactions, particularly for voice functions. Discrete inputs can also be used to determine
the states of various aircraft systems when this information is not available on a databus (e.g.
Weight-on-Wheels, Doors Closed, etc.).
 Iridium Antenna (1)
An antenna mounted on the top of the fuselage is used to communicate with both the Iridium
satellite network and the GPS satellite network.
 User Media Interfaces – SIM (1), CF (1)
There are two types of media available for the user to insert or remove from the Airbus Iridium
SATCOM System. The SCM contains a user accessible Subscriber Identity Module (SIM) card
slot for storage of the Iridium communications management information. The SDU contains a
front panel accessible Compact Flash (CF).
 Maintenance Interfaces – Ethernet (1)
An RJ45 jack on the front panel provides Maintenance Port access using an Ethernet connection.
