NIU3A-DCU-01
3 Function Slot MOSA Nano Data Concentrator Unit (DCU)
NIU3A-RDC-01 is a Modular Open Systems Approach (MOSA) Data Concentrator with low power high performance ARM Cortex -A53 processing. 8 GB RAM, 32 GB SATA Flash, 2 x 10/100/1000Base-T Ethernet.
The NIU3A-DCU-01 is compact rugged system solution ideally suited to support air, land and sea platforms requiring processing, monitoring, management and control of pre-integrated MIL-STD-1553, ARINC-429/575, CANBus and Discrete I/O interfaces. The NIU3A-DCU-01 takes advantage of NAI’s COSA® Architecture: a flexible, adaptable, configurable, modular and expandable solution that offers an almost infinite number of configurations while eliminating hardware and software NRE redesign. The COSA NIU3A-DCU-01configured with SC3, CD1 and TR1 modules adds support for serial, Chip Detect/Fuzz Burn and Thermocouple/RTD interfaces. The NIU3A-DCU-01 supports full remote operation over Ethernet or OS support includes PetaLinux, Wind River VxWorks HVP, DDC-I 653 Deos or GHS Integrity-178 tuMP for customer application development. Software Support Kit libraries and source code are supplied at no cost.
