SSDTU | Solid-State Data Transfer Unit

Adding Speed and Ease of Use to Your Data Transfers

Supporting Universal Serial Bus (USB) and Secure Digital (SD) media, the Solid-State Data Transfer Unit (SSDTU) represents the next generation of data upload and download equipment for your aircraft.

Easily accessible, high-speed media ports are conveniently located in the faceplate allowing for quick data file transfers between a USB drive or SD card and the aircraft’s avionics systems. The SSDTU interfaces with up to eight Universal Avionics Line Replaceable Units (LRU) creating a centralized uploading / downloading center for:

• Flight Management System (FMS) databases and Internal Flight Data Recorder (IFDR) downloads
• Terrain Awareness and Warning System (TAWS) terrain, airport and obstacles databases
• Vision-1^® Synthetic Vision System databases
• Charts, checklists and E-DOCS for the Application Server Unit (ASU) and its predecessor, Universal Cockpit Display (UCD) system
• UniLink^® Communications Management Unit (CMU) databases
• Flight Data Recorder (FDR) download

Data files are transferred between the media ports and interfacing LRUs using a high-speed Ethernet data bus connection. To accommodate a variety of aircraft configurations, the SSDTU is available in fixed-mount and portable versions.

The SSDTU is designed to eliminate the dependence on obsolete floppy and ZIP disks required by the DTU and DTU-100, as well as the CD/DVD-ROM of the Accessible Data Unit (ADU).
