Network TopologyThese 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.

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 and redundancy is possible.

Keywords in these types of networks are Rapid Spanning Tree– protocol, V-lan, Wireless Lan.

Specifics to Observe with CobraNet

The audio data is distributed via Bundles. In one bundle, a maximum 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.

CobraNet

The CobraNet-bundle

Specifics to Observe with CobraNet

The capacity of units working with Cobranet is measured in these bundles (for example, the N8000 can receive 4

bundles and can transmit 4 bundles)

It is important to calculate the necessary bandwidth before starting a project. For that there is the PC program

CobraCad.

In NetMax we have the possibility to exchange data with a PROMATRIX – system

The following features can be realised:

announcement/alarm into different Areas

announcement/alarm into different sectors of a PROSOUND area

audio signal from local or networking (RS485) DPM 4000

transmission of different BGM sources into the ELA areas

Transmission of all audio signals via fiber optics, CobraNet, network

Transmission of the RS 485 – signals for networking DPM 4000 via fiber optics.

Script Files

Script 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 with IRIS-NET software is the integrating tool for audio and control

• EV NetMax is the linking component to use distributed ProSound installations as life safety standard conform integrated systems

• EV NetMax can be used as audio expansion for Dynacord ProAnnounce systems

• EV NetMax can be interconnected via data interface, GPIO‘s and supervisioned audio lines

• User tailored operation, supervision and administration 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
