ARINC 429 interface board for commercial aviation avionics databus test and measurement introduced by UEI

June 13, 2019
Board features 24 receive and 16 transmit channels coupled to an FPGA to record, play back, process, and test ARINC-429 avionics databus traffic.

WALPOLE, Mass. – United Electronic Industries (UEI) in Walpole, Mass., is introducing the DNx-429-516 ARINC 429 interface board for use with UEI's Cube and RACKtangle chassis in commercial aviation databus test and measurement.

With 24 receive and 16 transmit channels coupled to a high-performance field-programmable gate array (FPGA), the board provides flexibility to record, play back, process, and test ARINC-429 avionics databus traffic.

The DNx-529-516 board supports 100 kHz and 12.5 kHz operation, selectable on a channel-by-channel basis. Users can set the channel speed 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 to enable the application to confirm correct information written to the ARINC 429 bus.

Users can disable the transmit drivers on the transmit/receive channels on a channel-by-channel basis to enable transmit channels to function as receive.

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

The included UEIDAQ framework provides an API supporting most operating systems and programming languages. The DNx-429-516 also is backed by the UEI's 10-year availability guarantee and 3-year warranty.
