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.
