MAC address: Short for Media Access Control, MAC is an address for an audio compo nent
that is burned into fi rmware in the component by its manufacturer, and cannot be changed.
Every component in a network has its own unique MAC address. The MAC address is printed
on a label outside the component. It is shown in hexadecimal format as 6 two-byte octets such
as:
00-0A-40-00-DC-2F

HiQnet Address: When you set up a network with System Architect soft ware, you assign an
address to each component. Each component has its own address, numbered from 1 to
64,999.
Internet Protocol (IP) Address: When you set up a network, you assign an IP address to
each component. The IP address identifi es each component. That way, certain data can be

sepa rated by periods. Each of the four numbers must be 0 to 255. For example:
192.168.0.1
Part of an IP address the network ID, and the remaining part is the host ID. The host ID is
either:

• A subnet number and a device address.
• A device address (if there is no subnet in the network).

To identify which part of the IP address is the network ID, you assign a Subnet Mask to the
network. A Subnet Mask is four numbers (0-255) separated by periods. "255" means "this
part of the address is the network ID". For example, if the subnet mask is 255.255.0.0, and the
IP address is 192.168.0.127, the network ID is 192.168.

To communicate between different networks, you need an IP Router. Any control data or
monitor data that is sent to the other network must go through the IP Router.

Wireless Access Point
The IP address allows components and computers on multiple networks to communicate with
each other through the use of an IP Router as shown in Figure 9.2.
Here is an application for a router. Wireless devices, because of bandwidth limitations, can not
be on a CobraNet network. However, the wireless devices can be on a non-CobraNet net work,
and access CobraNet devices through a router using IP addressing.
Discovery is the process where System Architect fi nds all the devices on an audio network
and lists them on the computer screen. Discovery cannot be done through an IP router, so a

Discovery Proxy is required. If you need to control or monitor components that are on
another subnet, you will need to specify ONE component on the remote network that can act
as a Discovery Proxy. Currently, all networked Crown products except the PIP Lite can
function in this capacity.
To add a Proxy, select Setup > Network Setup > Proxy addresses. Choose any one of the
components listed above, type its IP address in the box under Proxy Addresses, then click the
Add button. To remove a Proxy, select the IP address in the list and click the Remove but ton.
