Embedding 1553 and ARINC-429 Directly in the Cable


NLINE - Embedding 1553 and ARINC-429 Directly in the Cable

In the dynamic landscape of data communication, businesses and industries demand reliable and efficient solutions to ensure seamless connectivity. Alta Data Technologies, a leader in the field, has consistently delivered cutting-edge products, and their NLine series stands out as a testament to their commitment to excellence.

Alta’s NLINE avionics converters are the first and most unique Ethernet appliances in the industry. A real-time UDP server engine (no IP software stack like most other products on the market) provides direct data buffer and transmission control of MIL-STD-1553 and ARINC-429 interfaces.

The NLine products from Alta Data are a family of high-performance network interface cards (NICs) designed to meet the rigorous demands of data-centric applications. These cards are engineered to offer unmatched functionality and ease of deployment for aerospace platforms.alta data nline

These 1553 products for real-time Ethernet, Thunderbolt and USB 3 provide incredible system design choices for customers. The Alta Data team did an amazing amount of R&D to develop new packaging techniques to embedded their 1553 design directly into MIL-810G/461F qualified cable assemblies, meaning customers can literally just connect-up and go.

Almost every avionics or communication system implements an Ethernet topology, but most 1553 Ethernet converter products are processor/Linux based with unsecure IP network stacks that greatly slow down Ethernet communications. The NLINE designs are FPGA hardware-based UDP thin servers that provide real-time Ethernet/1553 bridging/conversion, reducing threats of viruses or internal hacking.

These products provide all the advanced controls of traditional 1553 interfaces, and can simultaneously auto bridge time-stamped 1553 UDP packets without any programming. There is a fast auto-boot feature where 1553 and MIL-1760 RX controls can be managed through standard socket communications as implemented in almost every OS, even DO-178 compliant systems.

For deployed systems, NLINE products provide an unmatched breadth of 1553 integration options. From saving card slots, or removing worriers about future hardware and OS versions, these products simplify 1553 integration. The Thunderbolt product will allow PCI Express capability, which means even real-time hardware interrupt applications can be done via a cable. And there is signal capture, which is an o-scope capability built-in to help troubleshoot cabling and possible security issues.
