iGU - instrumentation Gateway Unit
The iGU instrumentation Gateway Unit is a configurable gateway between instrumentation systems, Ethernet
networks and telemetry transmitters. The iGU contains a hardware based IEEE-1588v2 time engine, a 1PPS output from the 1588 time and IRIG Time Code Generator.
This small self-contained ruggedized unit, contains a layer 2/3 managed Ethernet switch, FPGA and quad-core ARM CPU which allows flexibility in data processing and protocol transforms. The FPGA can be customized to process proprietary Ethernet data streams and output them as Chapter 10. Also, the iGU provides built-in IRIG 106 Chapter 7 PCM conversion which allows the unit to function as an Ethernet-to-telemetry encoder and telemetry-to-Ethernet decoder.
