Frontpanel LEDs / USB-port

LEDs Frontpanel AUDIO CHANNEL LEDs: Volume monitor for input and output signals SIGNAL: green, >-25 dBu PEAK: red, 18 dBu, 3 dB space. Frontpanel LEDs NETWORK LEDs: ACTIVE: blinking or permanent on means data transfer via Cobranet MASTER: one of the network partners is automatically the master of the network. SYSTEM STATUS LEDs: Show status of unit and system READY is on after booting and shows satisfying operation FAULT shows error in unit or system. USB-connector: Connection to a PC when unit is assembled in a rack. POWER LED: Shows the unit is switched on.

Rearpanel Mainframe Connections

Rearpanel Mainframe Connections Ethernet Interface: RJ45 Ethernet connector for 100 BASE-TX / 10 BASE-T networks. RS 232-Ports: For connection of the N8000 with external devices like multimedia systems, building management systems, or PROANNOUNCE manager ASCII-string protocol easy to implement Configuration of ports via IRIS - Software Direct communication with PC via terminal program possible. Remote-CAN Bus: Connection to EV Remote Controlled Amplifiers or other units with CAN interface Connectors are in parallel STATUS led: shows activity at the CAN bus. 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. GPIO Control Port: 4 logical outputs, relay contacts SPST 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. 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. Keywords in these types of networks are Rapid Spanning Tree– protocol, V-lan, Wireless Lan.

Redundant networks

Redundant networks

Specifics to Observe with 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 .

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.

The following features can be realised: 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.
