The signaling is indirect. The air data computer is connected to another box, the air data converter. The air data converter is designed for a specific type of aircraft. It converts the synchro outputs from the air data computer into the formats required by the particular aircraft. These are probably synchro outputs as well, but might need to be scaled. (I don't think there is a standard.) The converter would also distribute the signals as needed, with a connector for each device that receives the data.
