NetAcquire Family Overview
The NetAcquire product family
supports telemetry applications as well as a wide range of other
mission-critical aerospace applications areas. Regardless of the application,
each member of the NetAcquire product family combines three key technologies:
flexible data acquisition, real-time signal processing, and high-speed

NetAcquire systems are powerful real-time input/output controllers with integrated processing and networking. They provide interfaces between the "real world" of analog, digital, and PCM serial signals and the "network world" of interconnected data analysis and display systems. Onboard processor options offer billions of cycles of processing in ruggedized form-factors as small as hand-held.
All hardware input/output interfaces are modular to allow convenient mix-and-match system configuration to support almost any application requirement. Expansion is available up to 512 input/output channels and all I/O interfaces are software-configurable without programming. Hardware configurability allows creation of a wide range of different instruments, from telemetry gateways to spectrum analyzers and communications bridges.
A NetAcquire system is designed for autonomous "always on" operation. No keyboard or monitor connection is required. Modular network interface hardware allows remote communication with a NetAcquire system over almost any type of network.
Full-featured and well-integrated software is essential component of modern-day instrumentation in order to ensure mission-critical reliability, reduced development costs and risk, and ease-of-use in the field. NetAcquire systems include all the software needed to work "out-of-the-box":
NetAcquire systems use the proven client/server
architecture for optimized real-time data acquisition and control. An
operational system is composed of two parts: the NetAcquire server and the
client. Core real-time activities such as data capture, processing and closed
loop control are executed on the NetAcquire server close to the point of sensor
connection. The less time-critical activities, such as data display, are located
on one or more client computers running Windows, Linux, or Java.
Even in applications where a NetAcquire system is physically close to the desktop operator interface, there are important benefits to the automatic NetAcquire partitioning of an application onto two processors each running its own purpose-built software environment.
Server-side Intelligence and Real-Time Processing
NetAcquire servers are equipped with multi-core
processors. The advantages of local processing include the ability to do
real-time data manipulation and simultaneous high-speed communication. The
real-time operating system avoids the timing limitations inherent in desktop
operating systems such as Windows. Additionally, high-speed local disk recording
can preserve critical data for future retrieval.
NetAcquire networking supports standard unshielded twisted pair Ethernet, fiber optic, and even wireless connections.
NetAcquire servers support unlimited simultaneous client connections, sharing data anywhere on the network. Both server and client software use industry-standard protocols and incorporate advanced network routing, error checking, and recovery – if a packet is lost or corrupted, it can be automatically re-sent.
NetAcquire servers can simultaneously communicate in real-time using multiple protocols including TCP, UDP, publish/subscribe and CORBA distributed objects.
NetAcquire "clients" are all other machines on a network that might want to
exchange data with a NetAcquire system. Client machines often are Windows or
Linux desktop machines, but also include other types of computers like file
