PXIe Avionics Interface Cards

Advanced · High Performance · Flexible

Connect Your PXIe-based Test Setup to Multiple Avionics Databuses

Ballard Logo

The Ballard 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 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.

The Highly Flexible Databus Interface Solution


Flexibility is key with the OmniBus II PXI Express avionics interface. This high-performance card includes an array of functional features and a modular I/O design. When ordering, just add the combination of modules to get the exact mix of I/O you need. When your needs change, the modules can be changed.

With the OmniBus II PXIe, you get:

  • Compatibility with both PXIe and CompactPCI Express (cPCIe) test systems
  • PXI triggers/syncs/clocks
  • Advanced timing: IRIG, 10 MHz, and PPS
  • Multiple protocols
  • Built-in test: PBIT, IBIT and CBIT
  • LabVIEW compatible hardware and driver available at

Get the Exact Interface You Need with the OmniBus II Modular Design


How it works...

OmniBus II cards include an array of functional features with the base configuration. Avionics I/O is added through the use of interchangeable modules. When ordering OmniBus II cards, you can specify the combination of modules for the exact mix of I/O you need. OmniBus II cards can accept a maximum of two modules, and each module has its own circuitry to handle the channels and protocols associated with it.

Users can develop their own software applications with the BTIDriver API. With only a few function calls, a program can operate the interface card and process messages to and from the avionics databuses. Code migrates seamlessly between BTIDriver compatible devices.


Optional CoPilot software provides easy-to-use, interactive tools for databus test, analysis, and simulation. CoPilot simplifies project development and provides added productivity through virtual instrument displays, flexible monitoring and analysis tools, and a powerful scripting engine.

OmniBus II PXIe at a Glance

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 3U size and include sixteen TTL level input/output discretes and IRIG time synchronization/generation. User software can indicate status by controlling the two LEDs.
