NetAcquire Serial/Telemetry (PCM) Input/Output

NetAcquire F30-SIO

The NetAcquire F30-SIO Serial Telemetry I/O system offers a new level of price-performance in COTS network-based telemetry/command gateway products. This system combines the power of real-time intelligent serial input/output hardware with the flexibility of high-speed network communications technology.

Compact Form-Factor Option

The NetAcquire F30-SIO performs as a low-cost real-time communications gateway between Ethernet networks 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 F30-SIO also supports data format conversion operations, frame synchronization, time tagging, header generation, and optional decommutation, all with best-of-class low latency real-time performance.

The NetAcquire F30-SIO industry-standard TCP/IP & UDP network interfaces provide communication access for a wide variety of computers and operating systems on any Ethernet network. The NetAcquire F30-SIO also provides integrated support for the FI 2010 TENA network protocols.

NetAcquire offers several companion software toolkits for use with these systems. The NetAcquire Server Extension Toolkit allows easy creation of custom data processing operations for execution in real-time on the NetAcquire F30-SIO.

NetAcquire F30-SIO supports advanced real-time processing extensions by allowing local execution of user-supplied custom code. Extensions include command generation, limited processing, and custom data headers.
