This allows the network designer to isolate network traffic from each other. For example,
when using wireless devices to control IQ components, the bandwidth limitation of wireless
devices will not allow them to reside on the same network with CobraNet. As a result, the
use of an IP router and a separate network allows the wireless controllers to access the IQ
components through the router using IP addressing. The IP address appears as four num-
bers (0-255) separated by periods, such as:
192.168.0.1
IQ or HiQnet Address: HiQnet or TCP/IQ components will be addressed with a unique
number from 1 to 64,000 and are assigned within the software. The Subnet Mask is four
numbers (0-255) separated by periods. For example, a subnet mask of 255.255.25.0 and an
IP address of 192.168.0.127 says that all IP addresses in that LAN are in the IP address
range of 192.168.01 to 192.168.0.255.
If a controller is on a different network than the audio components, communications must
occur through an IP router. discovery requires the use of broadcast Ethernet data packets
onto the network. These broadcast commands cannot be done through an IP router, there-
fore a Discovery Proxy is required. The establishment of this proxy is done in by naming the
