Avionics Interface TechnologiesMIL-STD-1553 Product OverviewGENERAL FEATURESThe Avionics Interface Technologies family of MIL-STD-1553 products are capable of supporting embeddedapplications as well as test, simulation, and analyzerapplications. The MIL-STD-1553 products are available inmultiple form factors, connecting to a variety ofcomputer bus designs. AIT also offers extendedtemperature, conformal coating, and conduction coolingoptions.AIT’s MIL-STD-1553 products are based on an FPGA-basedarchitecture. The FPGA design ensures compliance withthe MIL-STD-1553 protocol as well as enabling errorinjection beyond the standard protocol for testapplications. An onboard PowerPC CPU is integrated intothe FPGA, minimizing host CPU interaction by overseeinginstructions from the user host application. This enablesautonomous operation with minimal interaction to thehost CPU during time-critical embedded applications aswell as test and simulation applications.FLIGHT SIMULYZERFlight Simulyzer is a Windows-based MIL-STD-1553analyzer software for use with AIT’s boards. FightSimulyzer enables a user to easily setup: Bus Controller schedules and asynchronoussimulations Remote Terminal simulations Chronological Bus Monitor captures/recordingswith trigger and filter definitions Replay operationsThe intuitive GUI provides the ability to easily setup fullbus simulations and the bus monitor without anyprogramming. Flight Simulyzer supports all of the AITMIL-STD-1553 board operations including triggering andfilter setup and Data Corruptor TM . All setups are stored inwell-documented XML files allowing users to easily createsetups directly from program specific configurationdatabases.All MIL-STD-1553 products include an ANSI C applicationinterface and an object-oriented application interface forC++, C#, and Visual Basic. The ANSI C applicationinterface is a low-level interface that provides optimizedinteraction directly with the hardware. The objectorientedapplication interface supports C++ and .NETdevelopment environments for simplified softwareintegration using the latest development tools. Devicedrivers are included for Windows, Linux, VxWorks andother real-time operating systems.AIT has worked with National Instruments to optimizeinstrument drivers providing high level interfaces forLabVIEW, LabVIEW RT, and LabWindows applications.

EMBEDDED PROGRAMMINGThe MIL-STD-1553 SDK includes a low level C applicationinterface that is optimized for highly critical embeddedapplications that require efficient access to hardwaredata buffers. This low level application interface and itssupporting drivers are delivered with source code (forLinux, VxWorks, and others).OBJECT-ORIENTED PROGRAMMINGThe MIL-STD-1553 SDK also includes a high levelobject-oriented library that provides a C++ applicationinterface as well as a .NET application interfacesupporting C# and Visual Basic applications. These highlevel application interfaces provide an intuitive MIL-STD-1553 focused interface that simplifies softwaredevelopment when compared to the low level Capplication interface. It provides both hardware(the same PCI is common across all form factors)and development environment independenceinterface.LabVIEW, LabVIEW REAL-TIME, and LabWIndowsThe MIL-STD-1553 SDK includes high level support forLabVIEW and LabWindows applications. MIL-STD-1553instrument drivers are provided for both environmentsincluding support for operations on realtime targets(LabVIEW RT). The instrument drivers provide users with ahigh level interface that supports the setup andconfiguration utilizing configuration files created withinthe Flight Simulyzer GUI applications. The instrumentdrivers are optimized to take full advantage of theadvanced onboard functions provided by the FPGA andembedded processors of the MIL-STD-1553 hardwaremodules in order to support time critical real-timeapplications.REMOTE OBJECT SERVICES (ROS)Remote Object Services make AIT’s hardwareavailable to applications running in otherprocesses or on other hosts in the network. Itsupports heterogeneous networks of host wherethe server (hosting the MIL-STD-1553 hardware)may use a different operating system than theclients hosting the applications software. Thisservice is simple to configure and install andprovides intuitive support for distributedapplications that frees the applicationprogrammer from concern about the underlyingcommunications between the server and clienthosts.Avionics Interface Technologies3703 N. 200th StreetOmaha, NE 68022Tel: +1 402.763.9644Fax: +1 402.763.9645aviftech.com/1553sales@aviftech.comwww.instrumentation.itINSTRUMENTATION DEVICES SRLVia Acquanera 29, 22100 COMO (Italy) tel. +39.031.525391 - fax +39.031.507984 - info@instrumentation.it
