The current DASS is an upgrade to the Campbell Scientific CR10X data logger.  Additional memory for data storage and Ethernet connectivity will be added to enhance the CR10X’s ability to serve the user’s need.  The prototype that will be issued to Davidson Laboratories is expected to collect data and issue Campbell Scientific command listings to the CR10X via the Ethernet connection, whether remotely or locally.  This is the most basic functionality that the system can offer and meeting these minimum requirements is the team’s top priority.  In addition, the DASS will monitor its own temperature and voltage input levels, allowing for emergency protocol that will minimize data loss in the event of a failure due to exterior conditions.  The User Interface for this system will be done through a web browser.  An easy method for the user to download data and upload command files, the webpage interface will be the key method for communication to the DASS.  The DASS will connect to the CR10X via a RS-232 DB-9 style connection.  An optical isolator will also be built into the system so that connecting the CR10X to the DASS requires no additional equipment.  A battery backup system is still in the planning stages but is still considered a viable part of the final implementation.
