The AT-PMC-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 on up to 12 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 from our advanced API (Application Programming Interface) and VIP (Virtual Instrument Panel).

Hardware

The AT-PMC-429 card can be configured with up to 2 ARINC429 controllers from DDC, each containing 2 Transmit and 4 Receive channels, providing a maximum of 12 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-PMC-429 software includes :

> Virtual Instrument Panel

> Drivers & APIs

Virtual Instrument Panel

The AT-PMC-429 card comes with a “Virtual Instrument Panel” providing interactive control of all ARINC429 features. The control interface appears on the computer display and user manipulates these controls with a mouse or keyboard. The purpose of Virtual Instrument Panel is to help the user (mostly system integrators) to quickly setup and use the card, just like a stand-alone instrument with physical front-end knobs, controls and display without getting into programming intricacies.

Drivers & APIs

The AT-PMC-429 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, Linux, RT-Linux, VxWorks 5.5 and S 4.0 are available. Sample applications are included.
