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.
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.
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.
From the nonredundant minimum solution to the maximum redundant network.
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 .
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 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 can be interconnected via data interface, GPIO‘s and supervisioned audio lines
