Multiplexer / Demultiplexer (Telemetry Over IP)

With the NetAcquire Multiplexer Option, distributing serial and other digital data in real time has never been easier or more reliable. Now you can harness the power of real-time protocol processing to transport your specialized data and signal timing over commonly available networks.

The NetAcquire Multiplexer option, added to a NetAcquire server, reads a collection of electrical input signals and converts the resulting data streams into network packets. It then sends this aggregate data stream out over a network. A second NetAcquire server reads the data from the network and reconstitutes the data back into the equivalent electrical output signals at a remote location. It's that easy!

Reliability

The integrity of your data is maintained throughout the distribution process. NetAcquire Multiplexer preserves the relationship of the signals from the source side to the destination side. The time correlation of the source signals also is maintained and reconstituted on output.

NetAcquire Multiplexer has a unique output channel rate adaptation that prevents serial bit slips and data padding due to input-to-output timing mismatch. Other reliability features are automatic reconnect upon network infrastructure failures, quality of service channel prioritization (makes sure your most important data comes through first), automatic compensation for network delays, and the ability to re-configure most system properties dynamically so no system reset is needed. When combining the High Availability Option with the Multiplexer option, your data distribution process has the additional benefit of automatic multiplexer fail-over if a hardware or network problem occurs. NetAcquire Multiplexer protects your data from source to destination.

Unlike traditional time division multiplexer (TDM) systems, the NetAcquire Multiplexer option does not require a dedicated T1 or T3 connection, and is much more bandwidth-efficient because it uses packet-based technology. This saves network costs and frees up bandwidth for other uses.

NetAcquire Multiplexer also eliminates the restrictions of traditional point-to-point communications. Configurable packet routing supports transferring the same data to several destinations simultaneously. In addition, groups of channels from any number of different sources can be combined at a single destination. This routing flexibility reduces both infrastructure and management costs.
