6.5.15 Set up CMU/ACARS (option)
The AVIATOR 200/300/350 supports ACARS communication over Swift Broadband. The
connection to the CMU uses the same A429 lines as the ACU/BSU of the antenna system or
an AIS 380 Aircraft Interface Module
1
, This option is only available with certain types of
antennas, i.e. antennas controlled via modem on the coax cable or LGAs without control.
For a list of antenna that support the CMU/ACARS option see the table below.
You must have SBU software version minimum AVIATOR 200/300/350 (Level E):
1.07, AVIATOR 200D/300D/350D (Level D): 2.01, in order to support the
CMU/ACARS option.

When using the SBU/ACARS interface for SBB Safety Services (e.g. CPDLC
traffic) note that additional user traffic and interface connections to the SBU
shall be addressed in the Security Safety Assessment (SSA) of the particular
aircraft. The SBU does not comply to the ARINC-781 attachment 8, Security
Considerations. There is no segregation between the user interfaces. All
interfaces of the SBU shall be considered as 'Aircraft Control Domain'.
The setup of CMU/ACARS is divided into 3 areas:
• ACARS Aircraft Gateway (AAGW)
• Aircraft
• ACARS Ground Gateway (AGGW)
