ARINC 429, [1] the "Mark 33 Digital Information Transfer System (DITS)," is the ARINC technical standard for the predominant avionics data bus used on most higher-end commercial and transport aircraft. [2] It defines the physical and electrical interfaces of a two-wire data bus and a data protocol to support an aircraft's avionics local area ...

ARINC 424 is an international standard file format for aircraft navigation data. ARINC 429 is the most widely used data bus standard for aviation. Electrical and data format characteristics are defined for a two-wire serial bus with one transmitter and up to 20 receivers.

The ARINC 429 Specification establishes how avionics equipment and systems communicate on commercial aircraft. The specification defines electrical characteristics, word structures and protocol necessary to establish bus communication. ARINC 429 utilizes the simplex, twisted shielded pair data bus

2023年11月24日 · ARINC 429 uses the standard Mark 33 DITS bus, which is a Simplex twisted shielded pair data bus. ARINC specifies the hardware and data formats required for bus transmission. Hardware coupled to 1–20 receivers or sinks on a single twisted wire pair makes up a single connected transmitter or source.

ARINC 429 is a two-wire, point-to-point data bus that is application-specific for commercial and transport aircraft. The connection wires are twisted pairs. Words are 32 bits in length and most messages consist of a single data word. The specification defines the electrical standard and data characteristics and protocols.

2025年2月12日 · ARINC 629 protocol is a time-based, collision-avoidance protocol in which a fixed time slot is allotted to each terminal to access the bus and transfer data to the bus.

2021年10月21日 · ARINC 429 standards is also known as the Mark 33 Digital Information Transfer System (DITS) bus. Although used mostly in the field of avionics, these buses are also used in the field of ground vehicles, weapons systems, and …

ARINC 429 is the most commonly used data bus for commercial and transport aircraft. This document explains the origins of the ARINC Corporation, the data bus specification and where ARINC 429 is used.
