US Navy selects UEI to provide I/O Controller for LCAC SBC4 upgrade

Walpole, MA (June 4, 2016) — United Electronic Industries (UEI) is pleased to announce the US NAVY has selected the company’s DNR-MIL series I/O control chassis in conjunction with its VxWorks BSP as the new Command, Control, Computers, Communication and Navigation (C4N) SBC4 Control, Alarm and Monitoring System (CAMS) for the LCAC fleet. 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 analog 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.

About the DNR-MIL:The DNR-MIL is a new deployment of UEI’s popular RACKtangle architecture. Though the original RACKtangles are quite rugged the DNR-MIL series takes ruggedness to the extreme. Designed for use in the toughest environments, the new DNR-MIL is an ideal solution for military and aerospace deployments. The form factor is also ideal for a wide variety of commercial applications including use on oil drilling platforms and refineries, heavy machinery, outdoor test stands, wind/solar generators and any other I/O application that will be exposed to the elements.

The DNR-MIL offers the following key features.

  1. All connections via military standard 38999 series connectors
  2. Designed to meet MIL-STDs 461, 810 and 1275
  3. Waterproof with pressure relief valves to allow flight operations
  4. Extensive diagnostics and self-test
  5. Dual GigE ports operate independently or bonded/teamed
  6. Extensive software support for Windows, Linux, VxWorks, QNX and more
  7. Deployed as an I/O slave to a host PC or as a standalone device
  8. Supported by over 60 different I/O boards

Perhaps the most unique aspect of the new product is that it is a totally COTS product. Unlike most military grade products which need to be built to order, and may take many months or even years to deploy, the DNR-MIL is comprised of a COTS chassis, into which standard COTS I/O boards are installed. DNR-MIL units fully configured to precisely meet specific application needs can be delivered in 6 weeks or less!The DNR-MIL platform is supported by UEI’s popular deployment options. It will run as a slave to an application running on the applications host PC. It can also be deployed as a standalone controller running applications in either Linux or VxWorks. Finally, it can function as a Simulink target, and may run in conjunction with a Simulink host, or run the Simulink model standalone. As a member of the DNR family, the DNR-MIL is supported by over 60 different I/O boards including A/D, D/A, Digital I/O, ARINC-429/708/453, MIL-STD-1553, RVDT/LVDT, Synchro/Resolver, Serial, CAN and much more.

UEI & US Navy Continue to Work Together to Find Sustainable Solutions

UEI has been selected over and over for use in LCAC fleet applications, tackling obsolescence challenges while continuing to utilize existing cabling and more where applicable. 75 LCAC crafts needed a Control, Alarm, and Monitoring System (CAMS), as well as crucial fail-safe assurances and the ability to handle a variety of I/O signals. The Navy required a rugged and flexible commercial-off-the-shelf (COTS) data acquisition (DAQ) and control system that could easily be rehosted and deployed while running a hardened VxWorks OS supporting redundant Ethernet. The Navy selected the COTS UEI-CAMS embedded military rack system that included the required MIL-STD-1553 I/O, analog and digital I/O, RS-485, and more. UEI’s solutions helped reduce maintenance times by an impressive 75%. UEI’s 10-year availability guarantee an 3-year warranty (upgradeable to 10 years) will mitigate obsolescence and supply chain issues, securing easy access to replacement parts and compatible I/O equipment.

In fact, the Navy was so pleased with the UEI-CAMs solution that they leveraged UEI for another obsolescence protection program on their LCAC Sensor Interface Units (SIU). The Navy needed hardware that was smaller, easier to maintain, rugged, fail-safe, and sealed to IP66 specifications. UEI's modified COTS SIU system utilizes all existing cabling, making it a perfect drop-in match for the Navy’s LCAC fleet. The Navy’s Service Life Extension Program (SLEP) allows the existing LCAC fleet to be upgraded quickly, handle modern I/O demands, and remain viable for the long term with UEI’s availability guarantee and warranties, saving time and money.
