ARINC Specification 485, Part 2 specifies the ARINC 485-control protocol used by the LRUs described in ARINC Specification 628 Part 2. This document defines a multi-drop bus. The point-to-point configuration is also supported. The point-to-point bus is treated simply as a multi-drop bus with only one drop. There is one master LRU and one or more slave LRUs present on the bus. However; multiple buses may be connected in parallel, where each parallel bus operates independently from each other.

The purpose of this specification is to define the general Galley Insert (GAIN)standardization philosophy, provide comprehensive equipment interfaces, and disseminate the most current industry guidance. Part 1 covers the Controller Area Network (CAN) data interface attachments, envelopes, and data content to be considered between all galley equipment using a Galley Data Bus as described within this specification. This document is intended as the successor and replacement for ARINC Specification 812. This document contains significant improvements to CAN data interfaces.

ARINC 810 defines galley equipment physical attachments, envelopes, connections, and qualification guidelines for interchangeable galley equipment. Supplement 6 defines the new Extended Size 2, intended for oven installation and other equipment suited to this type of installation.

ARINC Specification 832 defines standards for the aircraft 4th Generation Cabin Network (4GCN) Cabin Distribution System (CDS) wiring, connectors, power, identification codes, space envelopes, and mounting principles. Design guidelines are included for informational purposes as these guidelines impact the interfaces and installation of cabin equipment aboard the aircraft.

This original "ATR" packaging standard provides a system of modularized equipment dimensions used in a wide variety of avionics installations. Connector standards, mating and holdown techniques are included.

ARINC 810 defines galley equipment physical attachments, envelopes, connections, and qualification guidelines for interchangeable galley equipment. Supplement 5 defines a size 6 galley insert, intended for microwave oven installation and other equipment suited to this type of installation. Supplement 5 also clarifies reference dimensioning for all GAIN sizes defined by ARINC 810.

The purpose of this specification is to define standard cabin equipment enclosures and provisions for equipment attachment on monuments. This standard is intended to enable simpler installation and maintenance of cabin equipment, resulting in time and cost reduction.

Cabin equipment installations tend to impose loads on aircraft electrical power systems not envisioned in the original airplane design. This standard provides guidance on the design of future aircraft air conditioning and equipment cooling systems. It also describes the environment in which cabin systems, including In-Flight Entertainment equipment are expected to operate.

This standard defines a new cabin network bus. While ARINC Specification 485: Cabin Equipment Interfaces, Part 2, Physical Layer – In-seat Protocol defined a low-speed serial communications interface between electronic equipment in the passenger seat, it is design-focused on obtaining status from in-seat electronic equipment. ARINC Specification 854 is a messaging protocol but does not preclude using the bus for video streaming or multicast. Cabin Equipment has evolved from the very simple to quite sophisticated systems. The resulting communications needs have surpassed the ability of ARINC 485 to provide the necessary data capacity and response times. The basic requirements for low latency, full duplex, elimination of ARINC 485 Master/Slave polling and lower weight drives the selection of 100BASE-T1 (per IEEE 802.3) as the preferred bus format.

This document defines general system architectural philosophy and specific design guidance for the design and interface of various cabin related equipment. System performance parameters are described for connectors, electrical interfaces, operational mode control/protocols, BITE reporting, reliability, environmental conditions, and software data loading. Supplement 7 defines an IEEE 802.11n compliant Cabin Wireless Access Point (CWAP) suitable for installation a wide variety of cabins. It also provides an update to the digital overhead monitor mounting provisions and connectors for compatibility with the CWAP definition.

This document provides airlines, airframe manufacturers, aircraft equipment suppliers, and others with information that is specific to data, software, and ground tools used in aviation configuration and data management. As a starting point, this document provides guidance on: Which standard to use in specific situations The use of and how integrity checks should be applied Common terminology in airborne software management Since airplanes started using software controlled hardware, there has been a need to standardize processes and terminology. This document is the centroid to which other software standards are related.
