DNA-429-5xx series 12 channel ARINC 429 Interfaces


United Electronic Industries (UEI) is pleased to announce the release of the DNA-429-5xx series of ARINC 429 Avionics bus interfaces. The DNA-429-566 offers 6 Tx / 6 Rx channels, the DNA-429-512 provides 12 Rx channels while the DNA-429-548 has 4 Tx / 8 Rx. All boards are fully compliant with the ARINC 429 spec and are software selectable for high speed (100 kHz) or low speed (12.5 kHz) operation.

Receive channels include automatic Label filtering so only data from selected channels is captured. The filter may be set to forward data from between one and 255 Labels, or may be disabled so all data is captured, regardless of source. Each received word may also be time stamped with the date and time of reception. Transmit channels may be set to transmit asynchronously or based upon a hardware controlled scheduler. Each channel supports a transmission table that allows up to 256 unique schedules. Asynchronous (non-scheduled) data may be sent with three priorities.

Software for the DNA-429 series is provided as part of the UEIFramework. The framework provides a comprehensive yet easy to use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, RTX, RT Linux and more. Finally, the framework supplies complete support for those creating applications in LabVIEW, MATLAB/Simulink, DASYLab or any application that supports ActiveX or OPC servers.

“The PowerDNA, UEILogger and UEIPAC cubes are very popular in aviation applications used for measuring and controlling parameters including pressure, stress/stain, vibration, temperature and a host of other physical phenomena. The addition of ARINC 429 allows the same I/O system to now monitor and/or control avionics” according to UEI President Shaun Miller. “It is now possible to combine analog and digital measurement with ARINC 429 in a single compact and robust system. It’s a perfect match for all types of flight test applications, many ground based applications and also an ideal platform to control flight simulators.”

About ARINC 429
ARINC 429 is a communications protocol that has become the primary communications interface on commercial aircraft worldwide. The ARINC 429 bus is used as the communications link by virtually all commercial avionics. It is also used as the link between avionics and flight control computers and actuators and system monitors throughout the aircraft. Aircraft from Boeing, Airbus, Bombardier, BAe, Embraer, Canadair, Cessna, Lear, Gulfstream, Hawker, Raytheon, Adam Aircraft, ATG, Spectrum, Bell, Piper and many more all rely on the ARINC 429 bus as their primary communications link.
