SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
(3) CMC Interactive Mode
(a) The SDU supports configuration data in CMC interactive mode for a Boeing 777
installation. If the CMC transmits a configuration data interactive mode command
addressed to the SDU on ARINC label 227, the SDU processes the command by
supplying the first page of configuration information and then resumes automatic
mode processing. The configuration data command is used to display
configuration information for the SATCOM LRUs (SDU and HPAs). The SDU
responds to the configuration data command from the automatic mode.
(b) The SDU does not support ground test and shop faults in CMC interactive mode.
If the CMC transmits a ground test or shop faults interactive mode command
addressed to the SDU on label 227, the SDU ignores the command.
