Ethernet connectivity for multichannel embdedded MIL-STD-1553 and IN-LINE thunderbolt™ products

Ethernet connectivity for 1553 Interface Advances Designs of Embedded and Portable Avionics Platforms

Alta Data Technologies (Alta) announces the release of a mini embedded mezzanine board for MIL-STD-1553 networks: MEZ-E1553™.  The MEZ-E1553 product provides 1-2 dual redundant 1553A/B/C channels with an Ethernet backplane interface on a small 3.6×5.6cm PCB. The product is available now for immediate delivery in Dual (BC/BM or MRT/BM) or Full Function (BC/MRT/BM) models.

“We’ve had several customers asking us to provide the inner workings of our popular, real-time Ethernet-1553 converter, ENET, for their embedded systems, and this resulted in the new MEZ-E1553 product. Customers can quickly integrate this small mezzanine PCB into their system. At the same time, they can utilize the AltaAPI SDK software, often without even recompiling its application. For new customers, the Berkley socket layer means the MEZ-E1553 will work with almost any operating system. The MEZ-E1553 compliments our Mini PCI Express embedded cards (MPCI2-1553) for systems like Com Express” states Harry Wild, VP of Sales for Alta.

Jake Haddock, CTO of Alta adds, “We offer a design reference card with complete schematics, STEP 3-d files, and break-out cables for bench testing. The customer can connect the MEZDEV-E01 board to the development computer via Ethernet. Then write their application while designing the hardware. The MEZ-E1553 is ideal for any rugged, custom requirement. The product also includes signal capture (o-scope) capability for troubleshooting 1553 cable issues and cybersecurity signal modeling.”

Generally speaking, almost every avionics or communication system implements an Ethernet topology. But most 1553 Ethernet converter products are processor-based with unsecure IP network stacks that greatly slow down communications. ENET, NLINE, and MEZ-E1553 designs are FPGA hardware-based UDP thin servers that provide a real-time 1553-Ethernet connection and reduce threats of viruses or hacking. These products provide all the advanced controls of traditional 1553 interfaces. Simultaneously, it can auto bridge time-stamped 1553-UDP packets without any programming.  There is a fast auto-boot feature. Therefore, standard socket communications can control data structures as implemented in almost every OS, even DO-178 compliant systems.

Details of NLINE-T1553™

Along with the MEZ-E1553 mezzanine board, Alta Data Technologies, LLC (Alta) announces the release of a MIL-STD-1553 Thunderbolt interface appliance: NLINE-T1553™.  The product embeds the industry-leading MIL-STD-1553 protocol engine, AltaCore™ directly into the Thunderbolt cable assembly.  With this new product, a customer has full-featured controls for 1-2 channels of 1553 BC, RT and BM functions via a Thunderbolt USB-C connection.  Combined with the standard AltaAPI™ software development kit (SDK), and advanced signal capture o-scope capabilities, this product offers unmatched 1553 functionality and ease of deployment for aerospace platforms. The NLINE-T1553 is available now for immediate COTS delivery.

Details of NLINE-U1553

Alta Data Technologies announces also a new MIL-STD-1553 USB 3 SuperSpeed adapter: NLINE-U1553™.  In detail, the product embeds the industry-leading MIL-STD-1553 protocol engine AltaCore™ technology directly into the 1553-USB cable assembly.  With this new product, a customer has all the advanced 1553 BC, RT, and BM controls of card-board-based products via USB connection.  With PCMCIA, PCCARD and Express Card interfaces of portable computers, Alta’s NLINE, USB and Thunderbolt™ products provide the best solution for mobile 1553 and ARINC applications. The NLINE-U1553 is available now for immediate COTS delivery.

About the products

To better define the product, Harry Wild, VP of Sales for Altam, has a statement about it. “The NLINE is a logical extension to the very successful real-time Ethernet ENET™ product line, and recently released 1553 Thunderbolt™ and USB 3 appliances.”  For deployed systems or lab usage, this product opens up many 1553 integration options.  Any example? The customer can take an application developed for desktops or servers. Then, use this exact same application on a notebook with an NLINE-T1553.  And there is signal capture, which is an o-scope capability to help troubleshoot cabling and cybersecurity issues.

Additionally, the new NLINE-T1553 product provides 1-2 channels of full 1553 network controls via a rugged in-line cable. Alta’s team did an amazing amount of R&D to develop new packaging techniques to embed our 1553 design directly into MIL-810G/461F qualified cable assemblies, even with operational, water immersion, and 60K altitude with the NLINE-E1553 Ethernet product.  Now customers can literally connect up and go.

“With our new manufacturing technology, we can design and build in-line 1553 and ARINC products to the utmost rugged capability with 38999 or custom connectors. The Thunderbolt interface provides full PCI Express (PCIe) functions of a 1553 interface board, even hardware interrupts. In most cases, you can use the exact same application code of a PCIe card to the NLINE-T1553. The customer can now decide to burn a PCIe card slot. Or use an external device via an in-line USB-C cable.” (Jake Haddock, Alta CTO).
