The AT-XMC/PMC-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. A wide selection of models is available: XMC and PMC, front and rear panel I/O, various ARINC channel counts and capabilities. They all include avionics discrete, timers, and IRIG Synchronization/ generation. All modes may be used in either conduction or air cooled systems.

The card is designed to transmit and receive messages up to 32 channels (Upto 16 channels for Receive (Rx) and 16 channels Transmit (Tx) mode). Each channel is software configurable for high or low speed (12.5k or 100k bits per second) and ARINC429 protocol requirements. To provide I/O and processing expansion capabilities, I/O are available on either rear user I/O connectors or front panel VHDCI Connectors. An onboard IRIG-B time encoder and decoder allow users to accurately synchronize single or multiple modules to a common time source. The ARINC data word can be decoded and sorted based on the Label and SDI bits and stored in FIFO’s. The card is integrated with powerful software that reduces development time.


The AT-XMC/PMC-A429 software includes Drivers & APIs. The product comes with a powerful set of library functions to access the entire ARINC 429 functionality. The drivers are designed in a modular fashion consisting of component functions and 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, Windows 7 and Linux are available. LabVIEW drivers available optionally.
