Learn more about the most common avionics databus protocols with this brief tutorial from Astronics Ballard Technology. This digital, command-response, time-division multiplexing network protocol is also used in many other military and commercial applications where fast, positive control is required. The standard defines the handshaking, data formats and timing requirements of the protocol as well as the electrical characteristics of the bus and the terminals' interface electronics. One terminal is designated as the bus controller; all others are remote terminals each with a specific terminal address. All transmissions are initiated by the bus controller transmitting a command word. Remote terminals monitor the bus and respond only to commands containing its own terminal address.

ARINC technical standard for the predominant avionics data bus used on most higher-end commercial and transport aircraft. ARINC is a data transfer standard for aircraft avionics. It uses a self-clocking, self-synchronizing data bus protocol Tx and Rx are on separate ports. The physical connection wires are twisted pairs carrying balanced differential signaling. Data words are 32 bits in length and most messages consist of a single data word. Messages are transmitted at either
