communicates with both IAUs using an RS-232 digital interface.

LRUs with the PFD. Each IAU contains VHF COM/NAV/GS receivers and system integration microprocessors
and is paired with the on-side display via a HSDB connection. The IAUs are not paired together and do not
communicate with each other directly.
