PRODUCT OF THE WEEK: Alta Data Technologies, LLC

Innovative packaging embeds 1553 network controls directly in the cable

This week’s product, the NLINE-U1553 MIL-STD-1553 USB 3 SuperSpeed adapter, brings users all the advanced 1553 bus controller (BC), multi-RT (mRT), and bus monitor (BM) controls of card-board-based products via USB connection. It comes in a small, rugged cable assembly that enables the customer to easily connect with standard 1553 jack connectors, or make their own custom cable with a Lemo break-away standard.

With NLINE Alta has combined the 32-bit 1553 FPGA protocol engine, AltaCore, with a real-time IP/UDP thin server bringing the MIL-STD-1553 protocol engine directly into the 1553-USB cable assembly. The customer can implement their application with the same feature-rich application programming interface, AltaAPI, as used with standard cards – often without even recompiling.

Alta’s new packaging techniques have made this possible. With its own injection molding capability, the company produces a wide variety of cable requirements for programs. If the customer has a particular cable or connector requirement, it can be quickly provided. Later this year, Alta will release Thunderbolt and ARINC-429 versions.

The NLINE-U1553 implements the USB 3 SuperSpeed technology for 1-2 dual redundant, independent 1553 channels. O-scope signal capture is also available on the first channel to troubleshoot bus signals. It is USB 2 backward compatible (but not recommended – as USB 3 offers superior throughput performance).

Combined with the standard AltaAPI software development kit (SDK), and advanced o-scope capabilities to troubleshoot 1553 signals, this product offers 1553 functionality and ease of deployment for aerospace platforms.
