CONFIGURATION COMMANDS
The Digital Audio Unit has a series of parameters that allow programming of the device.
These commands affect each cabin and programming parameters are stored and
controlled by the Digital Communications Platform.
3-digit commands program the Digital Audio Unit; the first digit indicates cabin number
(C) and the other two digits are the parameter to be configured or checked. Therefore,
commands for cabin 1 are 1xx, for cabin 2, 2xx, and so on.
