NIU2A

Multifunction Nano Interface Unit with optional ARM Processor

The NIU2A is a small, rugged, low-power, self-contained, multifunction I/O system. It is powered by an integrated MIL-STD-704F (designed to meet) power supply. The NIU2A can be fitted with up to two smart NAI Configurable Open Systems Architecture™ (COSA®) function modules. The NIU2A is configured to operate as a standalone Ethernet connected Remote Interface Unit (RIU) or optionally configured with access to the ARM Cortex-A9 processors operating as an integrated SBC, fully managing the I/O and a user software application. The NIU2A is configured with standard 10/100/1000Base-T (GbE) Ethernet ports or two optional 1 Gb 850 nm fiber-optic ports. Additionally, there is an RS-232 port for maintenance / diagnostic or configuration interface. Ideally suited for rugged Mil-Aero applications, the NIU2A delivers off-theshelf solutions that accelerate deployment of SWaPoptimized systems in air, land and sea applications.

The NIU2A rugged multifunction I/O platform provides scalable Ethernet or other communications interface linked I/O enabling networks including on-board vehicle, marine and aircraft platforms to field and expand digital network architectures for networkcentric operations. With dual function module capability, the NIU2A has the capability of being programmed as an I/O and communications protocol converter. The NIU2A integrates seamlessly within NAI’s COSA® family providing the most modular, agile and rugged COTS portfolio of embedded smart modules, I/O boards, Single Board Computers, Power Supplies and Ruggedized Systems.

Software

The NIU2A 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.

Accelerate Your Time-to-Mission™ With COSA®

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.
