[. . . ] The N8000 can be equipped with expansion cards in different ways: · · 4 Slots (module slots) for the expansion of the system with analog/digital inputs (AI-1, MI-1, DI-1) or outputs (AO-1) 1 network module slot for the installation of a network module, e. g. CM-1 CobraNetTM Module NetMax N8000 System Controller Owner's manual 15 Preparations · 1 DSP expansion module (DSP-1) for the expansion of the storage capacity and signal processing ATTENTION: It is essential to switch off the N8000 if you want to install or change a module. You will find detailed instructions in the data sheet of the corresponding module. System expansion with analog/digital inputs or outputs There are four slots at the rear of the N8000 which are intended to expand the systems with analogue or digital inputs or outputs. These slots have the marking AUDIO SLOT 1 to AUDIO SLOT 4 (see the figure on page 12). Any combination of the following types of expansion cards can be installed: · · · · AI-1 with 8 analog inputs MI-1 with 8 microphone inputs DI-1 with 8 digital inputs AO-1 with 8 analog outputs You can choose any slot for the installation of the expansion cards as the slot is automatically detected by the N8000 after the installation. System expansion with a network module An audio network interface for CobraNetTM can be installed in the network module slot on the rear panel of the N8000. The CM-1 module that is used for this purpose has two Ethernet connections (Primary and Secondary) so a redundant network can be established. Up to 32 digital audio input signals and 32 digital audio output signals can be transmitted simultaneously. Expansion of the DSP performance of the system The N8000 system controller has efficient DSP modules with a total computing power of 300 MIPS and a working memory for a maximum delay of 21. 8 seconds. If this does not meet the requirements of your application, the processing power as well as the working memory of the N8000 can be increased by installing the DSP-1 NetMax DSP expansion module. This allows the execution of more complex DSP programs and the use of longer delay times or additional delay lines. 16 NetMax N8000 System Controller Owner's manual Preparations 3. 3 Interface description Ethernet Interface By connecting the N8000 system controller via the Ethernet interface, the communication between the N8000 and one or several PC is possible. This allows the configuration of N8000 via IRIS-Net software. Furthermore, the whole connected system (consisting of N8000s and EV Precision Series Remote Control Amplifiers) can be operated and monitored. By using appropriate network hardware it is even possible to operate the N8000 via a wireless network (WLAN). The Ethernet interface on the rear of N8000 is a RJ-45 connector (8P8C). Both 10Base-T and 100Base-TX Ethernet standards are supported. The connections of the Ethernet interfaces can be seen in the following figure and table. Pin Assignment of Ethernet jack Pin Name 1 2 3 6 Tx+ TxRx+ Rx- Description Transmit+ TransmitReceive+ Receive- Pair 2 3 Colour T568A Green striped Green Orange striped Orange T568B Orange striped Orange Green striped Green The pin assignment of the Ethernet connector is shown in the following figure. The connector is viewed from the contact side. Pin Assignment of Ethernet plug NetMax N8000 System Controller Owner's manual 17 Preparations The maximum length of a connected cable segment is 100 meters in both Ethernet standards, in which two twisted pairs are used in one cable. Category 3 (unshielded CAT-3) can be used for 10Base-T communication. Category 5 (CAT-5) must be used for 100Base-TX. Cat-5 cable is compatible with 10Base-T as well. If the N8000 is connected via a patch cable to a hub/switch, the wiring of the cable at pin 1 of the first connector has to be connected with Pin 1 of the other connector; this is the same regarding the other pins as well. There are the T568A and T568B standards for the colors of the different wires used. However, T568B standard is more widely-used. [. . . ] In the following figure a star topology from three independent CAN bus systems is given as example. The three CAN buses are connected via two repeaters.

System with 5 power amps and 1 N8000 at the beginning of the bus. Termination plugs at the N8000 (first unit on the bus) and at amp 5 (last unit on the bus). . System with 2 amp-racks and 1 N8000/PC in the middle. [. . . ]
