ARINC 429 Interface Board Provides 24 Channels

United Electronic Industries’ DNx-429-516 ARINC 429 interface is designed for use with the company’s Cube and RACKtangle chassis. With 24 RX and 16 TX channels coupled to a high-performance FPGA, the board promises unprecedented flexibility to record, playback, process, and test their ARINC-429 traffic.

The DNx-529-516 board supports high speed (100 kHz) and low speed (12.5 kHz) operation, selectable on a channel by channel basis. The channel speed can be set to frequencies other than 100 and 12.5 kHz to support legacy devices that “push” the ARINC 429 standard. Supporting 256-word FIFOs on all channels ensures data integrity in both directions.

The board includes an ARINC 429 receiver connected to each transmit channel. This allows the application to confirm the correct information has been written to the ARINC 429 bus. The TX drivers on the TX/RX channels can be disabled on a channel-by-channel basis allowing TX channels to function as RX.

Channels may transmit asynchronously or based on a hardware-controlled scheduler supporting up to 256 unique schedules. The DNx-429-516 also provides a host of filtering capabilities including the ability to only return data from specific labels or from labels whose data has changed since the last read.

The included UEIDAQ Framework provides a comprehensive API supporting most popular operating systems and programming languages. The DNx-429-516 is also backed by the UEI’s 10-year availability guarantee and 3-year warranty. Pricing starts at $7,000 for the DNA-429-516 version and $7,150 for the DNR/DNF-429-516 versions.
