ARINC 429 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.

ARINC 429 utilizes the simplex, twisted shielded pair data bus standard Mark 33 Digital Information Transfer System bus. ARINC 429 defines both the hardware and data formats required for bus transmission. Hardware consists of a single transmitter – or source – connected to from 1-20 receivers – or sinks – on one twisted wire pair.

ARINC-429 defines the standard requirements and protocols for the transportation of digital data between avionic systems in commercial aircraft. These standards are followed by equipment manufacturers, enabling the interchangeability of avionics equipment.

ARINC 429 employs unidirectional transmission of 32 bit words over two wire twisted pairs using bipolar RZ format. This tutorial includes charts illustrating slew times and bit timing.

ARINC 429 defines both the hardware and data formats required for bus transmission. Hardware consists of a single transmitter – or source – connected to from 1-20 receivers – or sinks – on one twisted wire pair. Data can be transmitted in one direction only – simplex communication – with bi-directional transmission requiring two channels or buses.

ARINC429 is implemented as a simplex, broadcast bus. Each bus consists of a single transmitter – or source – connected to from 1-20 receivers – or sinks – on one twisted wire pair. Data can be transmitted in one direction only – simplex communication – with bi-directional transmission requiring two channels or buses.
