Introduction This manual describes the necessary safety precautions and gives a brief overview of the functionality of the Nest Rack. The STRYDE system is a seismic acquisition system for professional use, and the Nest Rack is used to recharge the batteries of the Nodes in this system. For operation and detailed description of the entire system, please refer to the STRYDE Operation Support Product File. 4. Product Overview The Nest Rack is a charging and data harvesting device that is used to charge up to 540 Nodes simultaneously. A total of six Nest Racks can be fitted in the STRYDE MLDU container. The rack is powered by a single-phase supply. Recharging of the Node battery and harvesting of the seismic data is performed by loading each of the six Nest Rack Shelves with a magazine of 90 Nodes. The Nodes are then charged wirelessly using the QI charging standard. The rate of charge is regulated by an Integrated Circuit on the Node and will automatically cease once the battery charge reaches a pre- determined level. Data harvesting is performed by a bespoke optical communication link, which is initiated by the rack-mounted touch screen, the harvested data is sent over ethernet via a series of ethernet switches, where finally it is ou…
