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-the-shelf solutions that accelerate deployment of SWaP optimized 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 network-centric 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.
