Network Topology

These distributors are called hubs or switches.

A hub sends all the signals to every connection.

A switch is more intelligent and sends the data packets only to the

destination where they are needed.

star network.


26/39

Network Topology

There are more complex networks (e. g. ring topologies)

that are possible. These must be realised with managed

switches. With these networks, higher safety andredundancy is possible.

Keywords in these types of networks are Rapid Spanning

Tree protocol, V-lan, Wireless Lan.

Network structures for typical stadium

sound systems

From the nonredundant minimum

solution to the maximum redundant

network.

Specifics to Observe with CobraNet

The audio data is distributed via Bundles. In one bundle, amaximum of 7 audio channels with 24 bit audio or 8 audio

channels with 20 bit audio can be transported .

CobraNet is a supplement to Ethernet.

Because of the popularity of Ethernet, all components are

cheap and available in a wide variety. Way to move audio

data over Cat5(6) or Fiber networks.

Script FilesScript files as advanced programming are extentions of the

operating elements in the IRIS program for use of multiple

commands coming from a single element.

EV NetMax can be interconnected via data

interface, GPIOs and supervisioned audio lines

User tailored operation, supervision andadministration from e.g. paging consoles, PC or

touch TFT screens and media control systems

Status and failure signalization in both worlds:Life safety Paging and ProSound
