Databus to Network Interfaces

OmniBusBox - Ethernet/USB Avionics Interfaces

Flexibility and Power.

OmniBusBox provides the solution to networked test and simulation systems. It has the power and flexibility to operate as a simple or intelligent peripheral (USB or Ethernet) or as a stand-alone embedded computer, and is a unique alternative to plug in cards. OmniBusBox can be ordered with up to two modules to support a variety of avionics databus protocols.

Key Features

  • PowerPC processor
  • High channel counts
  • Mixed protocols
  • PowerPC® user processor
  • Ethernet and USB ports
  • CompactFlash® slot
  • IRIG time synchronization
  • Can be upgraded/reconfigured
Astronics OmniBusBox

There is a newer version of this product available:

OmniBusBox II

Protocols & I/O

  • MIL-STD-1553
  • ARINC 429
  • ARINC 708
  • ARINC 717
  • CSDB
  • Serial (RS-422/232/423)
  • Discrete I/O

OmniBus Family

OmniBus is a highly-flexible and high-performance family of avionics databus interfaces combining a selection of industry-standard platforms (PCI/cPCI, VME, PMC and Ethernet/USB) with a wide-viariety of I/O choices (MIL-STD-1553, ARINC 429, ARINC 708, ARINC 717, Serial, CSDB and Discrete). This sophisticated OmniBus design allows users to order the exact number, functionality, and mix of protocol channels that they need. It also lets users upgrade or reconfigure their OmniBus (at the factory) as requirements change.

High-Performance Architecture

OmniBus products are built using an integrated board, core, and module architecture. PCI, cPCI, and Ethernet/USB boards include 1 or 2 cores, VME boards have up to 4, and PMC boards include a single fixed core. Each on-board core has a dedicated protocol processor, IRIG timer, and 3 sync and 3 trigger lines. These cores are the support circuitry for the I/O modules, which contain the interface to the databus protocol(s). Isolating the protocol interface on the I/O module provides the flexibility to create custom, user-specified configurations for single or mixed protocols. The protocol-specific OmniBus architecture provides a better solution with greater performance than general-purpose modular systems (such as IndustryPack™).

Modular Avionics Interfaces

Each Omnibus 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 two modules, and each module has its own circuitry to handle the channels and protocols associated with it.

Available Interfaces

  • MIL-STD-1553 - Up to 2 dual-redundant, single- or multi-function channels per module
  • ARINC 429 - Up to 16 channels per module
  • ARINC 717 - Up to 4R/4T channels per module
  • ARINC 708 - Up to 2R/2T channels per module
  • CDSB - Up to 4R/4T per module
  • Serial - Up to 4 Serial UARTs per module
  • Avionics Discrete I/O - 32 Discrete I/O per module

Standard Interfaces

  • Ethernet: 10/100 auto-speed sensing
  • RS-232 ports: 2
  • DIO: 2 inputs, 2 outputs plus 3 inputs, 3 outputs per module
  • RIG A/B input and output

Standard Features

  • OmniBus Modules: 2
  • Processor: IBM PowerPC®
  • Memory: 64MB SDRAM, 4MB Flash
  • CompactFlash slot: Type I/II
  • Real Time Clock
