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.
Software Architecture Far more
than just a messaging protocol, HiQnet™ is a software
architecture for real-time control and monitoring com-
bined with streamed audio. e HiQnet™ architecture
is truly the first to allow the system not to be tied to an
underlying physical medium. Whether a simple RS232
control command or fully streamed CobraNet audio and
HiQnet™ control over Ethernet, our architecture is flexible
enough to handle any situation.
System Applications e range of
HiQnet™-compatible devices offers previously unattain-
able benefits in diverse real-world systems:
