United Electronic Industries Announces The Release Of Its New High Performance ARINC-429 Interface with 16 TX Channels


Walpole, MA (December 20, 2016) — United Electronic Industries (UEI) today announced that its new high performance ARINC-429 interface I/O board, the DNx-429-516, is available for purchase. This 16-channel board is fully compliant with the ARINC-429 specifications and supports both high speed (100 kHz) and low speed (12.5 kHz) operation.

The DNx-429-516 is compatible with all of UEI’s family of I/O chassis. The channel speed is software selectable on a channel-by-channel basis. Data integrity, even when all channels are set in high-speed mode is assured with the use of 256 word FIFOs on all channels. The board is part of UEI’s Guardian Series and provides a diagnostic, on-board 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. Channels may be set to transmit asynchronously or based on a hardware-controlled scheduler. Each channel supports a transmission table that allows up to 256 unique schedules. Transmission schedule resolution is 100 microseconds. There is also a TX mode where a label is transmitted only upon receipt of data from a preprogrammed label. Asynchronous (non-scheduled) data may be sent with three priorities. High priority data is sent immediately upon completion of the current transmission, regardless of scheduled messages. Data sent with standard priority is transmitted during times when no scheduled data is being sent. Finally, the lowest priority is data streamed from a 256 word FIFO that is sent when no scheduled, high or standard priority data is being transmitted. Pricing starts at $7,000 with ARO availability ranging from 2 to 6 weeks depending on volume.
