1. INTRODUCTION
This manual is the user’s guide for PCIe® and PXI™ Express models of Ballard
Technology’s OmniBus® II family of products. Throughout this manual any
reference to the PCIe card applies to the OmniBus II PCIe card, reference to the
PXIe card applies to the OmniBus II PXIe card, and references to OmniBus and
OmniBus II apply generically to all the products in the designated family. This
guide gives the background for the OmniBus II PCIe/PXIe card, discusses special
features, describes the installation process, and references programming
alternatives.
1.1 OmniBus II Overview
OmniBus is a family of products that enable computer systems to communicate
with avionics databuses for the purpose of testing, simulation, and/or operation.
Each OmniBus unit can support more than one protocol and a large number of
channels. They are available as an interface card for popular computer standards
(PCIe, cPCIe/PXIe, etc.) and as a stand-alone bridge to other communications
protocols (USB, Ethernet, etc.). All common avionics databus protocols are
supported, including MIL-STD-1553, ARINC 429, ARINC 708, and ARINC
717. Other protocols (such as ARINC 575, ARINC 573, ARINC 453, etc.) are
also supported. Custom protocols are implemented upon request.

INTRODUCTION
Figure 1.2—OmniBus II PXIe card
The high-density modular design of the OmniBus family provides flexibility that
enables the user to select from many protocol, platform, and channel count com-
binations. Each OmniBus product can have at least two modules, and each mod-
ule has its own circuitry to handle the channels and protocols associated with it.
The high channel count and mixed protocol capabilities can be fully exploited
without the risk of overloading the host computer’s processor. IRIG and special
timing circuits allows channels, boards, and computers to be synchronized in
time to each other and to external devices.
OmniBus II is a newer, enhanced generation of the original OmniBus architec-
ture, and though there are similarities, components of the two generations are not
interchangeable. Figure 1.3 illustrates the modular architecture of the OmniBus II
PCIe/PXIe board.
