Customer-configurable 3U cPCI COTS System

NAI’s SIU31 is a highly configurable Rugged COTS System or subsystem ideally suited for military, industrial, and commercial applications that require high-density I/O, communications, Ethernet switching, and processing. The SIU31 uses one NAI field-proven, 3U cPCI board to deliver off-the-shelf, SWaP-optimized COTS solutions that Accelerate Your-Time-to-Mission™.

Adaptable Architecture

NAI’s Configurable Open Systems Architecture™ (COSA®) offers a choice of over 40 intelligent I/O, communication, and Ethernet switch functions, as well as Single Board Computer (SBC) options. Preexisting, fully-tested functions can quickly and easily be combined in an unlimited number of ways to meet system requirements. Individually dedicated I/O and communication processors allow mission computers to manage, monitor, and control the functions via single or dual Ethernet ports. Alternately, select one of NAI’s 3U cPCI SBC options.

All products are designed to operate under extreme temperature, shock, vibration, and EMI environments. EMI filters and gaskets meet or exceed MIL-STD-461F and MIL-STD-810G requirements.

Software Support Kit (SSK)

If required, the SIU31 offers a choice of 3U cPCI processors: NXP PowerPC™ QorIQ® P2041, Intel® Core™ i7, and ARM® Cortex®-A9, enabling customers to choose their ideal SBC. Each SBC supports NAI’s COSA architecture to maximize configurability, versatility, and field-proven reliability. Software support includes Wind River® Linux and VxWorks®, Xilinx® PetaLinux, and Windows® Embedded Standard 7. All I/O and communication libraries are available.

Eliminate man-months of integration with a field-proven, 3U cPCI Rugged COTS system from NAI.
