System Architecture

Hardware Architecture

Employing industry standard networking

technologies, HiQnet™ hardware is ready to be integrated into any system. By using Ethernet

as its main interface, HiQnet™ assures that products will operate within existing and new

infrastructures and provides all the remote access, connectivity, and control required.
