TechSAT’s latest product development is «Tiffi», a software solution that simulates parts of the SCI (secure communication interface), which is a gateway between Airbus’s Avionics Full-Duplex Switched Ethernet (AFDX) network and the open-world Ethernet side.
The SCI is a technology within Airbus aircraft, such as the A380, A400M, and A350, that translates the maintenance and health information (from the BITE) and the software data loading protocol.
In addition to the real SCI, Airbus has used a third-party solution based on a standalone industrial Linux PC with AFDX hardware for its tests on the ground. This solution has become obsolete and is not available anymore, but there is still a need for protocol translations at many test facilities.
Tiffi is a form-fit-function software replacement for this obsolete hardware and can be installed on any Windows or Linux computer, for example on the PC that hosts the CMS (centralized maintenance system) and DLCS (data loading and configuration system) tools.
Tiffi only uses a TechSAT A664 USB-network interface controller device, which combines a two-port Ethernet interface and dongle features for licensing. No further expensive AFDX hardware is necessary.
