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.
