Powerful 429/717 Interfaces

The USB 429 family of pocket-sized USB adapters enable computers to communicate with, simulate, test, and monitor ARINC 429 and 717 equipment and systems. These rugged USB 2.0 peripherals feature extensive 429/717 functionality and are compatible with virtually all modern PC laptop, desktop, and tablet computers.

These versatile interfaces are suitable for a wide range of applications in the lab and in the field. They support maximum data throughput on all ARINC channels and have a large 32 MB built-in memory. All power necessary for operation is provided via the single USB port. Plug and Play and Hot Swap features make them easy to install and move between computers.


Models are available with ARINC 429 channels only, ARINC 717 channels only, or a combination of both. All include eight avionics level input/output discretes and IRIG time synchronization/generation. They also provide useful non-standard functionality, such as a range of data rates, use of parity as data, and error injection. Once configured, the USB hardware performs all the protocol processing. It manages the reception, transmission, error checking, time-tagging and buffering of messages—freeing your software to focus on high-level application-specific processing.


Develop software applications with the included BTIDriver API, or use Astronics' optional CoPilot software. CoPilot provides powerful, easy-to-use interactive tools for databus test, analysis, and simulation.
