The AT-PCI-429-Simulator card is built as a replacement to M31ABM Arinc Simulator with necessary UI to emulate the original Arinc Simulator. This 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 from our advanced API (Application Programming Interface) and VIP (Virtual Instrument Panel).

Overview

HARDWARE

The AT-PCI-429-Simulator 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 modules receive circuitry to filter and sort incoming data by label and destination bit as well as provide multilevel data specific interrupts or hardware triggers. Under reset conditions PCI-A429-V2.0 Card will be set to its nominal frequency and nominal voltage levels. The user can select the required voltage and frequencies by writing to a specific control registers in read write control logic.

SOFTWARE

The AT-PCI-429-Simulator 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 and RT-Linux are available. LabVIEW support is also available optionally. Sample applications are included.

Additional features of AT-PCI-429-Simulator

The transmission data rate and voltage level of each transmit channel can be changed in high and low rate data transmission by writing to appropriate registers in read write control logic (FPGA). The voltage and frequency that could be set using the registers for respective channels are as shown in the table below.
