SNAP DNP I/O represents a lower-cost, non-proprietary, standards -based way
to aggregate instrumentation values; track energy consumption, monitor
equipment status and other variables; control remote equipment; and
otherwise bring all of a utility's most critical assets under the scope of
a DNP SCADA network, without incurring the significant cost of deploying
and maintaining traditional RTUs.

Opto 22 products are sold through a worldwide network of distributors,
partners, and system integrators.

For the past six years, FORTUNE magazine named NI one of
the 100 best companies to work for in America.

Additionally, the SNAP DNP I/O system 's modularity and distributed
intelligence allows for quick and seamless expandability, giving users the
ability to monitor and control newly added facility equipment without
reprogramming or altering existing systems.

NI Alliance Partner Radical Systems Creates PXI-Based Data
Acquisition System for Complex Aerospace Testing

National Instruments (Nasdaq:NATI) today announced that Boeing
(NYSE:BA) selected an NI LabVIEW- and PXI-based solution for
acquisition of vehicle launch environments on the ground-based
midcourse defense system vehicle flight test program.

SNAP DNP I/O is also ideally suited for remotely monitoring, controlling,
and managing auxiliary systems and equipment not typically included under
the umbrella of SCADA, such as security and access control for substations.

For this system, Boeing required an advanced data acquisition
solution that could acquire and analyze simultaneous high-speed inputs
and display them in real time on a remote computer located in the
launch control bunker. The hardware is
therefore suitable for deployment throughout the entire SCADA environment.

"Within any utility, SNAP DNP I/O is appropriate for gathering meter data
and logging performance data from equipment for the purposes of optimizing
