RS 232-Ports For connection of the N8000 with
external devices like multimedia systems,
building management systems, or PROANNOUNCE

GPIO Control Port 4 inputs 0 .. 10 V freely
programmable Can be used as digital (on/off) or
analog (e. g. volume control) input Digital
inputs 0V low, 10 V high Analog inputs via
potentiometer 0 .. 10 V or from multimedia system.

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
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.

Redundant networks

• From the nonredundant minimum solution to the
  maximum redundant network.

CobraNet
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.
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 .
31
The CobraNet-bundle
32
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.
33
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

36

• EV NetMax can be interconnected via data
  interface, GPIOs 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
  worldsLife safety Paging and ProSound
