DNx-429-516-024, DNA-429-516-024, DNR-429-516-024, DNF-429-516-024

The DNA/DNR/DNF-429-516-024 are ARINC 429 communicationsinterfaces for UEI’s popular “Cube” / RACKtangle / FLATRACK I/O chassisrespectively. The DNx-429-516-024 offers 16 TX/RX channels and 8dedicated RX channels. (The 8 dedicated RX channels are a new featureand are available on “-024” designated boards) The TX drivers on theTX/RX channels can be disabled on a channel-by-channel basis. To use aTX/RX channel as RX simply disable the TX driver on that channel.

All boards are fully compliant with the ARINC 429 spec and supportboth high speed (100 kHz) and low speed (12.5 kHz) operation. Thechannel speed is software selectable on a channel by channel basis. Thechannel speed can be set to frequencies other than 100 and 12.5 kHz tosupport legacy devices that “push” the ARINC 429 standard.

Data integrity, even when all channels are set in high speed mode isassured with the use of 256 word FIFOs on all channels. and in bothdirections. The board is part of UEI’s Guardian series and provides adiagnostic, on-board ARINC-429 receiver connected to each transmitchannel. This allows the application to confirm the correct informationhas been written to the ARINC-429 bus.

Channels may be set to transmit asynchronously or based on a hardwarecontrolled scheduler. Each channel supports a transmission table thatallows up to 256 unique schedules. Transmission schedule resolution is100 microsecond. There is also a TX mode where a label is transmittedonly upon receipt of data from a pre-programmed label. Asynchronous(non-scheduled) data may be sent with three priorities. High prioritydata is sent immediately upon completion of the current transmission,regardless of scheduled messages. Data sent with standard priority istransmitted during times when no scheduled data is being sent. Finally,the lowest priority is data streamed from a 256 word FIFO which is sentwhen no scheduled, high or standard priority data is being transmitted.

The DNx-429-516-024 series provides a host of helpful filteringcapabilities. The board may be set to only return data from specificlabels. Data from up to 255 labels may be read or the board can beset to read data from all labels. A “new data only” filter compares thereceived label data to the most recent previous reading and onlyreturns data if something has changed. Data may also be filtered basedon the SDI bits.

Software for the DNx-429-516-024 is included with the board. TheUEIDAQ Framework provides a comprehensive, easy to use APIsupporting all popular Windows programming languages. Factorywritten and supported drivers are also included for Linux and areavailable for other popular real-time operating systems includingQNX and VxWorks. Finally, the UEIDAQ Framework supplies completesupport for those creating applications in all popular data acquisitionand control packages, including LabVIEW, MATLAB/Simulink, as well asany application which supports ActiveX or OPC servers.
