After a successful multi-year collaboration and product distribution partnership, National Instruments will no longer distribute AIT's MIL-STD-1553, ARINC 429, and ARINC 664 PXI instruments after August 17, 2018. Despite the conclusion of this product distribution partnership, AIT is committed to the long term supply, support, and maintenance of all of our products including our PXI and PXI Express avionics interface instruments. AIT will continue to offer test instrumentation both directly and through multiple valued distribution channels and partnerships. (For a list of our North American Sales Representatives Click Here. For a list of our international distribution partners Click Here). AIT will always provide full applications support and maintenance services for all of our PXI products, including any AIT products purchased from National Instruments. We are also currently in the process of establishing new product partnerships and distribution channels for our PXI and PXI Express products, expect more details and a big announcement soon!

Avionics Ethernet

The use of Ethernet is becoming the more and more common in avionics network applications. As a result there are several adaptions and profiles of Ethernet, specifically for avionics applications that are becoming standardized in order to increase interoperability. This post is intended to provide a brief overview of the most common Ethernet adaptions currently utilized in avionics systems.

Bridging between legacy data buses and Ethernet

As more and more avionics systems begin to employ the use of Ethernet, there are an increasing number of application requirements for devices to operate as a bridge between Ethernet networks and MIL-STD-1553 bus systems. A few of the types of applications for MIL-STD-1553 to Ethernet bridges are:
