The AT-PCI-429 card provides a flexible, powerful ARINC429 avionics data bus interface card for the development and maintenance of commercial avionics. The card is designed to transmit and receive messages up to 24 channels. Each channel is software configurable for high or low speed (12.5k 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 RAM and/or FIFO’s. The card is integrated with powerful software that reduces development time. All data bus functionality is supported by our advanced API (Application Programming Interface) and VIP (Virtual Instrument Panel).

 

HARDWARE

The AT-PCI-429 card can be configured up to 4 ARINC429 controllers from DDC, each containing 2 Transmit and 4 Receive channels, providing a maximum of 24 channels. Each controller has a 128 x 32 bit static RAM, four 32 (words deep) x 32 (bit) Receive FIFO’s and two 32 (words deep) x 32 (bit) transmit FIFO’s. Look-up tables loaded into RAM enable the module’s receive circuitry to filter and sort incoming data by label and destination bit as well as provide multilevel data specific interrupts or hardware triggers.

SOFTWARE

The AT-PCI-429 software includes Drivers & APIs. The card comes with a powerful set of library functions to access the entire ARINC429 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 are available. Linux, RT-Linux and LabVIEW support is also available. Sample applications are included.
