The standard ADP-5.5 multihole air data boom has a full-duplex RS-485 data interface. RS-485 enables the configuration of multidrop communications links. Furthermore it uses a differential balanced line pair (like RS-422 and ARINC-429), is very immune to interference and can span large distances.
The multidrop feature allows to connect multiple listeners like for example two flight control computer (FCC) to a single RS-485 TX line as it it shown on the attached diagram. This way a single ADP-5.5 air data boom can serve multiple listener devices.
