This allows the network designer to isolate network traffic from each other. For example, in
the case of the use of wireless devices in the control of IQ components, the bandwidth limi-
tation of wireless 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 numbers (0-255) separated by periods, such as:
192.168.1.241
IQ Address: TCP/IQ components will be addressed with a unique number from 1 to
65,535 and are assigned within the IQ software. A separate utility is then run which queries
the network and establishes what IQ components and their associated MAC addresses are
present. An IP Address and IQ Address can then be assigned to each IQ component.
The MAC address does uniquely identify each TCP/IQ component and can be used to estab-
lish the physical location of the unit. The binding of the MAC address to the IQ address
through the use of the TCP/IQ Utility assures that each TCP/IQ component is physically in
the right position. The use of the IP address establishes the Local Area Network (LAN) and
what components reside within that LAN. The Subnet Mask associated with each IQ Compo-
nent tells what IP addresses can be assigned to a particular LAN. The Subnet Mask is also
