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 Ballard's optional CoPilot software. CoPilot provides powerful, easy-to-use interactive tools for databus test, analysis, and simulation. See "Software" tab for more information.

The easiest way to use the ARINC 429 or ARINC 717 functionality of your USB 429 adapter is with CoPilot, Ballard's Windows-based software. CoPilot is an intuitive, interactive program that simplifies the testing and simulation of ARINC 429/717 systems. In CoPilot, you can quickly build transmit schedules and enter and display data in meaningful engineering units. The Sequential Monitor captures, records, filters, displays, and exports 429 traffic. Equipment ID and label definitions are built into the CoPilot 429 database. For ARINC 717, CoPilot allows you to view, analyze, simulate and record bus activity from an aircraft Digital Flight Data Acquisition Unit or Digital Data Recorder output databus. CoPilot features include virtual instruments, hardware and software playback modes, and scripting. CoPilot also supports MIL-STD-1553, ARINC 708, ARINC 664/AFDX® protocols and limited serial communications. You can add CoPilot at anytime. However, you will receive a discount when you purchase CoPilot bundled with the hardware.

Users can develop their own software applications with the included BTIDriver API:

  • With only a few function calls, a program can operate the USB hardware and process messages to and from the avionics databuses.
  • Functions include routines for transmitting, receiving, scheduling, recording, time-tagging, and manipulating data.
  • With BTIDriver, application code migrates seamlessly to and from other Ballard devices, reducing development time and costs.
  • A translation DLL is included to easily import applications from legacy Ballard products that are not compatible with BTIDriver.
