Over 70 different modules to choose from

Customer Configurable 3U cPCI Intelligent I/O Board

NAI's latest generation 3U cPCI Multifunction I/O and Communication Board, the 75G5, can be configured with up to three smart function modules. Ideally suited for rugged military, industrial, and commercial applications, this low-power/high-performance board delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems.

Adaptable Architecture

NAI’s Configurable Open Systems Architecture™ (COSA®) offers a choice of over 70 smart I/O, communication, and Ethernet switch functions, providing the highest packaging density and greatest flexibility of any multifunction I/O board in the industry. Preexisting, fully-tested functions can be combined quickly and easily in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.

Software Support Kit (SSK)

The 75G5 includes SSKs to support multiple operating systems. In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.

Eliminate man-months of integration with a configured, field-proven 3U cPCI board from NAI.
