OmniBus II PXIe Avionics Interface

The OmniBus II PXI Express (PXIe) card is designed for use in multi-slot PXIe and CompactPCI Express test systems. It enables these systems to interface with multiple avionics databuses for testing, validating and simulating commercial and military avionics equipment and systems. The card 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 PXIe is the next-generation of Ballard’s 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 the CoPilot® software—perform lab, production and flight test verification and simulation right out of the box.

Each Omnibus II product includes an array of functional features to which I/O is added through the use of interchangeable modules. A combination of modules can be added to get the exact mix of I/O required when ordering an OmniBus product. Each OmniBus PXIe card can accept up to two modules, and each module has its own circuitry to handle the channels and protocols associated with it.

  • MIL-STD-1553
    • Up to 2 dual-redundant, single- or multi-function channels per module
  • ARINC 429
    • Up to 16 Tx/Rx configurable channels per module; advanced ARINC 429 modules are also available with added test features
  • ARINC 717
    • Up to 4R/4T channels per module
  • ARINC 708
    • Up to 2R/2T channels per module
  • Serial
    • Up to 4 Serial UARTs per module
  • Avionics Discrete I/O
    • 32 programmable Input/Output per module

  • 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


OmniBus II Part Numbers
The part number for an OmniBus II product is a combination of the platform number, module number(s), CoPilot code, and options. Each platform core can accept one module. A core without a module may be used for future expansion.

NOTE: OmniBus and OmniBus II modules are incompatible and cannot be interchanged between systems.
