The NetAcquire H50-SIO Serial Telemetry I/O systems offer a new level of price-performance in commercial off-the-shelf (COTS) network-based telemetry/command gateway products. This system combines the power of real-time serial input/output hardware with the flexibility of high-speed network communications technology.

PCM Serial Configuration

The NetAcquire H50-SIO performs as a low-cost real-time communications gateway between Ethernet networks (e.g., TMoIP) and high-speed PCM serial devices. Network clients, such as engineering workstations, can now receive and send telemetry as well as command data directly from and to range, satellite and avionics communications equipment. The NetAcquire H50-SIO also supports data format conversion operations, frame synchronization, time tagging, header generation, and decommutation, all with best-in-class low latency real-time performance. An extensive suite of real-time processing functions is available without the need for programming.

The NetAcquire H50-SIO industry-standard network interfaces and TMoIP provides communication interoperability with a wide variety of devices via RCC 218, IRIG 106 Chapter 10, and TmNS.

NetAcquire offers several companion software toolkits for use with these systems. The NetAcquire Server Extension Toolkit allows the easy creation of custom data processing operations for execution in real-time on the NetAcquire H50-SIO.
