The AT-PC104 Plus-429 card enables electronic systems to interface with commercial and military avionics data buses. They provide extensive functionality and are used to communicate with, simulate, test, and monitor ARINC429 equipment and systems. This high-density high-performance card is suitable for applications ranging from test equipment to rugged deployable systems. The card is designed to transmit and receive messages up to 16 channels. Up to 8 channels for Receive (Rx) and 8 channels Transmit (Tx) mode. Each channel is software configurable for high or low speed (12.5k/50k or 100k bits per second) and ARINC429 protocol requirements. The ARINC data word can be decoded and sorted based on the Label and SDI bits and stored in FIFOs. The card is integrated with powerful software that reduces development time. All databus functionality is supported from our advanced API (Application Programming Interface).


The AT-PC104 Plus-429 software includes Drivers and APIs. The card comes with a powerful set of library functions to access the entire ARINC429 functionality. Source code is provided for samples, and detailed documentation. The drivers are designed in a modular fashion consisting of component functions & application functions. The user’s test program can be developed with few calls to the driver, by using the set of Application functions provided. Driver and high-level API libraries for Windows XP, Linux are available.
