Customer Spotlight

A leading military contractor performing diagnostic testing and calibration functions on aircraft wanted to reduce the number of physical connections required for their test computer. The contractor was using a combination of Ethernet, serial and digital I/O interfaces between their test computer and aircraft transport rack (ATR). The contractor wanted to limit the costs associated with a custom design by leveraging as much off-the-shelf material and products as possible.

Sealevel provided a solution that reduced the connections to the test computer to one USB cable and one Ethernet cable. A standard 2U Relio industrial computer chassis houses off-the-shelf SeaI/O data acquisition modules and a common industrial Ethernet switch.
