Latest high-performance ARINC Board to provide flexibility to record, playback and process

United Electronic Industries (UEI) announced the release of the DNx-429-516 ARINC 429 interface for use with UEI’s Cube and RACKtangle chassis. With 24 RX and 16 TX channels coupled to a high-performance FPGA, the board provides 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.

256 word FIFOs on all channels ensure 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 provides a host of helpful 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, easy to use API supporting most popular operating systems and programming languages. The DNx-429-516 is also backed by the UEI’s revolutionary 10-year availability guarantee and 3-year warranty.
