ARINC 429 / ARINC 717 - PC USB Interface

This board provides an interface between a PC USB port and an ARINC 429 or ARINC 717 avionics bus. It can send and receive both high and low speed 429 as well as send and receive 717 at configurable word rates. All received data is time-stamped with a 1ms resolution, and data can be logged to a file for later analysis.

The physical interfaces for both 429 and 717 can be switched from bipolar +/- 5V levels to unipolar 3.3V levels for direct connection to digital logic without requiring level conversion.

Examples of typical data captures are shown below:
