SUNNYVALE, Calif.—April 26, 2017— Real-Time Innovations (RTI), the Industrial Internet of Things (IIoT) connectivity company, today announced the availability of its safety-certifiable Data Distribution Service (DDS) implementation for the LynxOS-178 2.2.4 Real-Time Operating System (RTOS). RTI Connext DDS Cert reduces the time, cost and risk associated with integrating avionics systems by providing an off-the-shelf connectivity framework that eliminates the need to develop, certify and maintain custom communications software.

Connext DDS Cert has proven certifiability to the DO-178C avionics safety standard. It is available with a complete certification package for the most stringent DO-178C Design Assurance Level (DAL), DAL-A. Connext DDS Cert is also aligned with the FACE 2.1 Technical Standard, including optional support for the FACE Transport Service Segment (TSS) application programming interface.

"The combination of Connext DDS Cert and LynxOS-178 provides avionics manufacturers with a completely standards-compliant and safety-certifiable platform," said Niheer Patel, product manager for Connext DDS Cert at RTI. "Both products support POSIX and ARINC interfaces, are aligned with the FACE standard, and are available with DO-178C certification evidence."
