R (1) Digital Outputs
R The connections with the CFDIU is a type-1 system. This type of
R system has an ARINC 429 input from the CFDIU and an ARINC 429 output.
R This system is thus capable of two-way communication with the CFDIU
R (Ref.31-32).
R The radio-communication equipment receives the frequency data through
R words from the RMPs. These words have a structure and a refresh rate
R defined in ARINC 429 characteristics specification.
R On the output bus, each VHF transceiver transmits the labels 356,
R 377, 350, 354.
R
R This table contains all the output parameters in the digital form.
R They are sorted as per the numerical order of their output label.
