ARINC 429 Transmitter

Product Description

The DNx-429-516 are 16 channel ARINC 429 communications interfaces for UEI’s popular Cube, RACKtangle and FLATRACK I/O chassis respectively. The DNx-429-516 offers 16 TX channels. All boards are fully compliant with the ARINC 429 spec and support both high speed (100 kHz) and low speed (12.5 kHz) operation. 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 microsecond. 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 which is sent when no scheduled, high or standard priority data is being transmitted.

Software for the DNx-429-516 is included with the board. The UEIDAQ Framework provides a comprehensive, easy to use API supporting all popular Windows programming languages. Factory written and supported drivers are also included for Linux and are available for other popular real-time operating systems including QNX and VxWorks. Finally, the UEIDAQ Framework supplies complete support for those creating applications in all popular data acquisition and control packages, including LabVIEW, MATLAB/Simulink, as well as any application which supports ActiveX or OPC servers.
