SnS Wire Fault Detection: Detect and Pinpoint DataBus Wiring Faults

For MIL-STD-1553, CAN buS, CAN bus (FD), ARINC-825-4 ,and ARINC-429

Sital’s Safe and Secure (SnS) Wire Fault Detection IP is a technology that’s applicable to all data bus interfaces. This technology provides continuous real-time detection and location of intermittent or continuous open or short circuit faults in data bus cables, bus couplers, connectors, stubs, LRUs and bus terminators.

These include both single-wire and two-wire faults, along with short circuit faults between two data bus wires or between one data bus wire and ground.

The capability to detect and locate intermittent faults enables preventive maintenance prior to faults becoming continuous, when they can render a data bus inoperative. Metrics and advanced diagnostics can be viewed on a computer screen to see how the system is running.

With Sital’s wire fault detection technology, a disconnected or shorted wire is registered immediately as is its location and effect on a system. Sital’s wire fault detection sensors provide the fastest fault detection and are the most accurate in registering intermittent faults during flight.

In addition to resolving many no-fault-found issues, it can distinguish between module and wire faults. The result is more accurate network prognostics and the ability to implement an effective repair strategy that resolves potentially mission-threatening failures.

Cyber Security

Using enhanced physical layer monitoring, Sital’s Safe and Secure (SnS) technology provides continuous real time authentication, along with the capability to detect and locate intermittent and continuous open or short circuit faults.

This capability enables the SnS sensor to provides the required security against “spoofing” (impersonation) attacks that can result in devastating results for mission execution or flight safety.
