OmniBus VME
OmniBus VME cards provide interfaces for avionics databuses. Features include a PowerPC processor, Ethernet, serial, CompactFlash, PMC site, digital I/O, and IRIG. The cards can be ordered with
up to four modules to support a variety of avionics databus protocols.
OmniBus VME has the power and flexibility to operate as a simple or intelligent I/O board, as the VME system controller, or as a remotely controlled Ethernet peripheral. In stand-alone systems, the
on-board PowerPC processor can boot automatically and run without host intervention. Complex applications like data converters, data servers, and simulators with dynamic data generation may be
entirely implemented on a single OmniBus VME.
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™).
