OmniBus II - PCIe Avionics Interface Cards for Multiple Protocols

Flexible Avionics Interfacing

OmniBus II PCIe cards, part of of the Omnibus family, enable computers to interface with multiple avionics databuses with flexible, modular I/O choices.

Key Features

  • Supports multiple protocols in one card
  • 3 syncs and 3 triggers per core
  • Advanced timing: IRIG, 10 MHz, and PPS
  • Built-in test: PBIT, IBIT and CBIT
Astronics OmniBus II PCIe

Applications

  • Product development and validation
  • Production testing
  • Simulation of databus and I/O system traffic
  • Data servers
  • Data recorders
  • System analysis and integration testing
  • Performance monitoring and analysis

Multi-Protocol Avionics Databus Interface

The OmniBus II PCIe card enables computers and networks to interface with multiple avionics databuses for testing, validating and simulating commercial and military avionics equipment and systems. It is highly configurable and includes two internal Cores that can be populated with a variety of databus protocols and discrete I/O modules.

The OmniBus II PCIe is the next-generation of Astronics' popular OmniBus product with faster I/O and processing capabilities. With the newest advanced set of MIL-STD-1553 and ARINC 429 modules, users can verify wave form compatibilities, test functions of bus shorts and opens, and—when combined with our CoPilot® software—perform lab, production and flight test verification and simulation right out of the box. Readily available as Commercial Off-The-Shelf (COTS) products, the PCIe interface is perfect for challenging simulation, test, interface, and data recording applications.

Hardware

OmniBus II modules used on this card feature the latest 6th generation protocol engines and bus mastering to yield high performance. Power is obtained from the backplane bus—no supplemental power is needed. All cards are standard half size and include sixteen TTL level input/output discretes and IRIG time synchronization/generation. User software can indicate status by controlling the two LEDs.

Specifications

Modular Avionics Interfaces

Each Omnibus II product includes an array of functional features to which I/O is added through the use of interchangeable modules. When ordering an OmniBus product, you can add the combination of modules to get the exact mix of I/O you need. Each OmniBus product can accept at least two modules, and each module has its own circuitry to handle the channels and protocols associated with it.
