DNx-1553-553, DNA-1553-553, DNR-1553-553, DNF-1553-553

The DNx-1553-553 is a high performance, two channel MIL-STD-1553 interface. Each channel operates fully independently and provides a complete dual, redundant 1553 interface. Each channel may be set as 1553a or 1553b, and the "b" interface fully implements specification notices 1 and 2. Each channel is transformer coupled, though direct coupling is available as an option.

Most 1553 functions are implemented by the on-board FPGA. This greatly reduces the burden placed on the Cube CPU and ensures the DNx-1553-553 does not interfere with the functionality of other I/O boards installed.

Each channel may be independently configured as Bus Controller (BC), Remote Terminal (RT) or Bus Monitor (MT). As a Bus Controller, the board supports all standard BC-RT, RT-BC and RT-RT transfers and Mode Code, One-shot, and Broadcast messaging. The Remote Terminal support allows the board to be set at a single RT address, or to emulate up to 31 different RTs on the bus. The RT implementation supports single, double, and circular message buffering. Bus Monitoring (MT) mode provides the ability to monitor all activity, or select activity based upon RT address or Mode Code. In addition to monitoring data, MT mode monitors time tags, errors status and RT response time. Finally, each DNA-1553-553 channel may be set to simultaneously act as an RT and an MT.

The DNx-1553-553 is well suited for the harsh environments sometimes encountered in flight testing applications. The board is specified for operation from -40° to +85°C, from 0 to 60,000 feet. The system is also fully tested for operation at 5 g vibration and up to 50 g shock.

The DNx-1553-553 includes our 1553 API, which has been designed to offer simple, easy-to-use controls and yet maintain the ability to access all 1553 functionality. The software driver is compatible with all popular operating systems including Vista, Windows, Linux as well as many real-time OS's including INtime, QNX, RT Linux and more. Software support is also included for all popular programming languages and applications packages including LabVIEW.

UEI's Technical Master Class Series: Introduction to MIL-STD-1553: Getting started with programming

In this introduction to UEI’s 1553 offering, we provide an overview of the I/O board and begin to answer the question, "How do I use a variety of programming languages to access the full functionality of UEI’s MIL-STD-1553 I/O components?"

UEI Technical Master Class: MIL-STD-1553 RT/SAs

In this session, we cover the Remote Terminal/Sub Addresses element of 1553 system. This includes learning how to set data words in the RT/SA for a RT-BC command, and how to read data words from the RT/SA after a BC-RT command.

UEI Technical Master Class: MIL-STD-1553 Bus Controller

In this session, we take a detailed look at the Bus Controller in a 1553 avionics system. This includes the Frame-based vs Multi-rate commands, FIFO base bus writer and how to modify the code to get the data you want.

UEI Technical Master Class: Understanding the MIL-STD-1553 Bus Monitor

In this continuation of our MIL-STD-1553 Master Class, you will learn all the ways our Bus Monitor can help you with your applications. We will cover adding a Bus Monitor to a channel, 2 ways to use the Bus Monitor to help debug missing words and commands from the bus, Raw Mode vs Full Message Mode and a COTS application for recording what the Bus Monitor sees.

1553 One Time Command | UEI Minute Video

The 1553 major minor frame scheduler is designed to run cyclic, multi-rate commands over and over again at preselected frequencies. Sometimes you need to send a command, or series of commands, just once. We've developed a technique to help you accomplish this.

Optional Event Notifications

UEI's MIL-STD-1553 API can be used to set up events that notify your application of important things happening in the system.

1553 Timing Precision

High-speed, precise timing on a UEI MIL-STD-1553 I/O board is not determined by the API you use but by the FPGA on the board itself.

Using LabVIEW to Interface with MIL-STD-1553

UEI hardware is designed to be software flexible which means it works with a variety of different languages and programs including National Instruments' LabVIEW.

1553 Status Word Error Injection

UEI's MIL-STD-1553 IO board not only runs all the components of a 1553 system, but also allows engineers to stress that system by injecting errors.

In a previous video we detail how you can also stress the system with bus errors: https://ueidaq.wistia.com/medi...

MIL-STD-1553 Error Injection

While UEI’s MIL-STD-1553 allows users to simulate a complete and fully functioning 1553 system, it also provides you the ability to inject errors to fully test your system’s real world error handling capabilities.
