MIL-STD-1553B is the military specification defining a Digital Time Division
Command/Response Multiplexed Data Bus. The 1553 databus is a dual-redundant, bidirectional, Manchester II encoded databus with a high bit error reliability. All bus communications are controlled and initiated by a main bus controller. Remote terminal devices attached to the bus respond to controller commands. MIL-STD-1553B defines specifications for terminal device operation and coupling, word structure and format, messaging protocol and electrical characteristics.

AIT’s MIL-STD-1553 hardware modules for PXI, PCI, PCI Express, VME, and VXI provide advanced features and functionality to support even the most demanding test and simulation applications.

AIT ARINC 429 Products

ARINC stands for Aeronautical Radio, Inc., a private corporation organized in 1929, and is comprised of airlines, aircraft manufacturers and avionics equipment manufacturers as corporate shareholders. ARINC was developed to produce specifications and standards for avionics equipment outside the government for domestic and overseas manufacturers.

The ARINC429 Specification defines the standard requirements for the transfer of digital data between avionics systems on commercial aircraft. ARINC429 is also known as the Mark 33 DITS Specification. Signal levels, timing and protocol characteristics are defined for ease of design implementation and data communications on the Mark 33 Digital Information Transfer System (DITS) bus.

ARINC429 is a privately copywritten specification developed to provide interchangeability and interoperability of line replaceable units (LRUs) in commercial aircraft. Manufacturers of avionics equipment are under no requirement to comply to the ARINC429 Specification, but designing avionics systems to meet the design guidelines provides cross-manufacturer interoperability between functional units.

AIT’s ARINC 429 hardware modules for PXIPCIVME, and VXI provide advanced features and functionality to support even the most demanding test and simulation applications.

Avionics Full-Duplex Switched Ethernet (AFDX) is a data network, patented by international aircraft manufacturer Airbus, for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service (QoS). AFDX is a worldwide registered trademark by Airbus. The AFDX data network is based on Ethernet technology using commercial off-the-shelf (COTS) components. The AFDX data network is a specific implementation of ARINC Specification 664 Part 7, a profiled version of an IEEE 802.3network per parts 1 & 2, which defines how commercial off-the-shelf networking components will be used for future generation Aircraft Data Networks (ADN). The six primary aspects of an AFDX data network include full duplex, redundancy, determinism, high speed performance, switched and profiled network.

AIT’s ARINC 664 test instruments can be used in test and simulation applications that are required to transmit and receive data over the ARINC 664 avionics databus. AIT’s instruments use small form-factor pluggable transceivers (SFP) and support copper or fiber optic physical network interfaces.

Using an FPGA based architecture, with multiple embedded processors, the ARINC 664 instruments provide onboard support for upper layer protocol processing (A653, UDP, IP) and utilize DMA to provide optimal data throughput. All ARINC 664 protocol operations, including VL traffic shaping, redundancy management, and IP fragmentation and reassembly, are handled onboard.
