Out 1 potential free for fault signalisation

Out 2..4 referenced to ground,

+5V output can be used to operate external
relays or LEDs with max 200 mA.

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.

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.

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.

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.

-
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
