To connect instrumentation back to the DAQ system in the control room, strain and voltage cable bundles are laid inside the covered trenches along the east and south side of the test bay. The bundles come out of the trenches and terminate into connection boxes at several locations throughout the bay perimeter to provide easy hook-ups for the sensors attached to specimens.

NEEShub is a web-based centralized data repository for managing, sharing, storing and publishing data. A complete listing of MAST sensors and calibration information is also available in the NEEShub Sites Map section.
