UEI’s DNR-MIL chassis was selected as it was flexible enough to meet all the system’s myriad requirements, rugged enough to be deployed on the boat and at the same provided a fully COTS solution. UEI’s 10-year availability guarantee was also a primary consideration as the solution must be maintainable for many years.
Based on a robust PowerPC processor, running VxWorks with fully redundant Ethernet connectivity to the boat’s host computer, the UEI system replaces the previous controller, and provides a much smaller, easier to maintain and more reliable solution.
The VxWorks support was critical as it allowed much of the software running in the earlier system to be preserved. I/O provided by the CAMS unit includes analogue input and output, digital I/O, 16 serial ports and MIL-STD-1553 all connected through standard military style 38999 connectors. Key to the Navy’s decision to select UEI’s DNR-MIL was it met the required MIL-STD-810 and -461 environmental specifications.
