The configuration, operation and monitoring of a P 64 system are effected by the PC Software IRIS-Net - Intelligent Remote & Integrated Supervision.

The P 64 Audio Matrix includes up to 32 audio channels, mixer and matrix functions, signal processing and extensive control and monitoring functions. Several P 64 can be connected via a CobraNet™ audio and control network so that a large, decentralized audio system can be assembled.

The P 64 also manages the DYNACORD remote amplifiers including its speaker and system monitoring functions. The connection is directly effected via CAN to the P 64.

The P 64 meets all relevant safety requirements. All audio connections, interfaces and processor systems are monitored and displayed in case of fault. By using CobraNet™ redundant networks can be assembled.

Introduction

1.2 P 64 features

The P 64 is an all-purpose digital audio Matrix Manager with outstanding performance features. A high quality system design provides excellent audio quality and clear sound, which is achieved by the application of high-end 24 Bit A/D and D/A converters with 120 dB volume range, highquality input and output circuits in the analog domain and digital signal processing with optimized 48 bit double-precision algorithms. Hence, the P 64 is even particularly suitable for demanding applications in theatres, concert halls, big churches etc.

The P 64 is highly flexible due to the modular hardware design which renders many other applications possible. Four slots with 8-channel audio modules at the rear of the device offer up to 32 local audio channels. Each slot can be equipped either with an audio input module or an audio output module. So, various configurations (e.g. 8-in/8-out, 8-in/16-out, 8-in/24-out, 16-in/ 16-out, 24-in/8-out) can be realized in only one single device. In addition, P 64 can be equipped with a CobraNet™ network module. Therefore, several P 64 can be integrated in a network and be connected to a large, sophisticated system.

The signal processing in the P 64 is effected on powerful audio signal processors where, depending on the stage of expansion, up to 8 DSPs are available. The software contains a multitude of freely programmable signal processing components. Among other things, these are filters with all possible characteristics, parametric and graphic equalizer, crossover network, matrix router and matrix mixer, delays, dynamic functions, etc. Diverse configurations can be created by combining and connecting these DSP blocks. The programming is done via the PC software IRIS-Net. With that, you choose the desired components from a signal processing library , place them in a working a rea on the screen and wire them to a signal flo w chart. Thus, the resulting DSP configuration has only to be transferred to the P 64 and is ready for immediately use.

The powerful signal processing allows complex configurations for the adjustment and control of the sound system, depending on the application or type of event. Thus, the sonic quality of PA speakers, monitor speakers, front fill systems as well as of the sound reinforcement of adjoining rooms, lobbies, areas for the staff etc. can be optimized and tuned individually. In other words, the P 64 copes with every application - even with large and complex systems - absolutely exactly and reliably.

In addition to the audio processing, the P 64 is equipped with diverse control functions. The scheduling with calendar function makes it possible to program one-time or recurring eve nts . The recurrence can occur annually, monthly, weekly, daily, hourly or even within smaller time intervals. Furthermore, daily programs can be set up and can also be combined to weekly operations. With the event control, reactions to certain events or system states can be configured, e.g. in case of overstepping or undershooting of threshold values. Faults in the device or in the complete P 64 system are detected automatically and can be displayed on the PC screen or transmitted to external sites if necessary.

Faults and other events are recorded in an internal log file with date and time. Furthermore, it can be defined which types of errors or events should be recorded. The log can be read out and displayed on the screen at any time. In P 64 individual functions can be integrated into complex operations. For example, several parameters can be set with various values or states in a scene and can be changed manually or automatically at any time.

Introduction

The P 64 is equipped with all relevant interfaces by default in order to provide the connection to the network and external components. The Ethernet port makes the connection to existing building networks (intranet) and communication via the Internet possible. Ethernet is also the common connection between one or more P 64s and a PC with IRIS-Net software for the configuration, control and monitoring of the P 64 System. Two RS-232 serial port s can be used in order to control the P 64 from external multi-media systems, e.g. Crestron™ or AMX™. For that, an open interface protocol is available. The remote CAN-bus serves as connection to DYNACORD remote amplifiers. Up to 100 amplifiers can be attached via CAN to one single P 64. Together with additional P 64s and amplifiers they can also be integrated in a complex and powerful audio system. The P 64 also has a control port which offers freely programmable control inputs and outputs. Switches, potentiometers or external control voltages can be connected to the control inputs (GPIs). Any logic and analog functions can be programmed. External elements which can be used to signal certain states can be attached to the control outputs (GPOs). A PC can be connected to the USB port on the front faceplate if the P 64 has been installed in a rack and the Ethernet port cannot be reached easily. V ia the USB interface t he network parameters of the P 64 can be edited and files containing the entire P 64 configuration can be transferred.

The highest standards regarding construction and mechanical working have been followed. The chassis is extremely robust and, therefore, effectively protects the electronics against outside influences. A temperature controlled fan provides thermal stability and also constant ambient conditions inside the device. All audio interfaces are electronically balanced and have Phoenix screw terminal connectors.

By reading this instruction manual you will get to know many additional features and functions of the P 64. Please read on attentively and keep this manual in order to be able to consult it at any time.

Introduction

1.4 Installation instruction

The P 64 has to be set up and installed so that both air supply and ventilation are ensured on both sides of the device. The direction of ventilation is from left to right when you look at the front faceplate. Devices with an opposing routing of air flow should not be installed in the same rack. When installing the P 64 in a rack, a free air duct between the sides of the P 64 and the side panel of the rack to the upper rack ventilation must be observed in order to ensure sufficient air ventilation. There must be at least 100 mm free space for ventilation above the rack.

ATTENTION: The maximum ambient air temperature of +40°C should not be exceeded in order to ensure failure-free operation.

Standard installation rails should be used when mounting an P 64 in transport racks in order to prevent twisting of the front faceplate.

The P 64 must be protected against: dripping/splashing water, direct solar radiation, high ambient air temperature or direct impact of heat sources, high moisture, heavy vibrations and dust deposit.

If these conditions cannot be ensured permanently, maintenance is obligatory at regular intervals in order to prevent any breakdowns which are mainly due to negative environmental influences.

If the P 64 is transported from a cold to a warm environment, moisture may condense at the core. The device should not be started up before warming to the changed temperature (approx. after 1 hour). If a solid or liquid is in the housing, cut the device off from the mains power at once and have the device checked by an authorized service center before re-using it.

1.5 IRIS-Net

The IRIS-Net (Intelligent Remote & Integrated Supervision) PC software is used to configure and operate the P 64 Audio Matrix. The configuration of the P 64 can be done offline (i.e. without connection between the PC and the P 64) on the PC. After the connection between the PC and the P 64 has been established via Ethernet, the configuration can be transmitted to it. In addition to configurations, IRIS-Net can also be used for extensive supervision, control and monitoring of P 64 Matrix Managers (and DYNACORD Remote Amplifiers which are connected to them).

The latest version of IRIS-Net is available at www.dynacord.com.

Control Elements and Connections

2 Control Elements and Connections

2.1 Front Faceplate

The front faceplate of the P 64 has level and status displays and it offers also the possibility to connect a PC via a USB interface. SIGNAL / PEAK-LEDs exist for all 32 audio channels. The channels are combined to groups of 8 and assigned to the audio-slots 1 to 4 at the rear. Additional LEDs inform about the states of the network, system and device and give a quick overview of whether the system is working faultlessly or if a problem has occurred.

SIGNAL / PEAK-LEDs

These LEDs serve as level meter display for input and output signals. The SIGNAL-LED begins to flash at -25 dBU and indicates if a signal generally exists at the input or at t he output. The PEAK-LED flashes when the P 64 is operated close to the level meter’s limit. The limit is approx. at

+18 dBU. The maximum level meters is +21 dBu so that there is 3 dB of head room until the final clip limit is reached. The PEAK-LEDs should only flare up sporadically in case of dynamic peaks. If the PEAK-LED of an input flashes constantly or very often, you should reduce the corresponding input signal slightly. If the PEAK-LED of an output flashes constantly, the internal gain should be reduced or else the connected device will be permanently overdriven.

NETWORK-LEDs

If the P 64 is operated on an audio network, e.g.

CobraNet™, these LEDs show the status of the network.

The ACTIVE-LED flashes or twinkles when audio data is

sent or received via the network. If the LED is off, no

communication via the audio network is taking place. The MASTER-LED is on when the P 64 serves as clock-master - in case of CobraNet™ it is also named the conductor. There is always only one master in an audio network, i.e. the MASTERLED will only be illuminated on one P 64 within the network. If the unit currently functioning as clock master breaks down or is removed from the network, another P 64 will take over this function automatically.

P 64 Digital Audio Matrix

Control Elements and Connections

SYSTEM STATUS-LEDs

These LEDs indicate device or system states. The READY-

LED is on when the device has booted after switch-on and

when it is ready for operation. An illuminated FAULT-LED

indicates an internal error in the P 64. During the

configuration of the P 64, it can be specified which errors should be displayed. If the FAULT display is on, the error should be identified promptly. This can be done using the detailed diagnostics within the IRIS-Net PC software. The source of the fault has to be remedied immediately.

POWER-LED

This LED is permanently green when the P 64 is powered

on. If the ON indication is not illuminated, even though the

device is switched on, this device may not be connected to

the power supply system or the primary fuse may be faulty.

USB Interface

A PC can be connected at the front panel via the USB

interface. Thus, it is possible to connect the P 64 with a PC

even it is already installed - i.e. when the Ethernet interface

at the rear panel is perhaps no longer accessible. Via the

USB interface the network parameters of the P 64 can be

edited and files containing the entire P 64 configuration can be transferred. You can find the necessary USB driver in the subdirectory \Driver\USB Netmax Driver in the IRIS-Net setup directory. Please see chapter Interface description for more information on technical details concerning the USB interface and the other interfaces of the P 64 which are described in the following section.

Control Elements and Connections

2.2 Rear Panel

There are all connections for analog and digital audio signals, control interfaces and the power supply at the rear panel of the P 64.

AUDIO SLOTs

The AUDIO SLOTs 1 - 4 a re module slot s for th e inst allation of P 64 audio modules. There are both analog and digital input and output modules available. Also, a module for microphone input sensitivity is optionally available. Each slot can accept any module so you can equip those inputs and outputs which you need for your specific application. The P 64 detects the type of the module automatically and offers the corresponding configuration possibilities.

ATTENTION: The P 64 has to be switched off if you want to change or install a module. You will find detailed instructions in the data sheet of the corresponding module.

Network Module Slot

This slot is provided for the installation of a network module,

e.g. CM-1 CobraNet™ module. There are all 64 audio

channels - 32 inputs and 32 outputs - internally available at

this slot. The CM-1 allows up to 32 digital audio input signals

and 32 digital audio output signals to be transmitted via a

CobraNet™ network simultaneously. Thus, several P 64 matrix managers can be connected to create a large, distributed audio system. The P 64 automatically detects an installed network module. The module can be configured in the PC software IRIS-Net.

ATTENTION: The P 64 has to be switched off if you want to change or install a module. You will find detailed instructions in the data sheet of the corresponding module.

Control Elements and Connections

ETHERNET Interface

A computer and/or other P 64 devices can be connected via

the Ethernet interface for 100Base-TX / 10Base-T Ethernet

networks. Normally this connection is established via a

standard (straight throug) Ethernet cable and an Ethernet

hub or a switch. If the P 64 is to be connected directly with a computer or another P 64, a crossed Ethernet cable (crossover cable) must be used.

RS-232 Interfaces

The P 64 can be connected to external devices, such as

multimedia system (AMX™, Crestron™) or facility

management systems via the two RS-232 interfaces. All

P 64 functions and parameters can be controlled and

monitored via RS-232. Communication is done using an

ASCII parser which is easy to implement. Thus, a P 64

system can be easily combined with media and touch panel

control systems. A PC can also be connected to the RS-232

port to access P 64 parameters using a terminal program like Hyperterminal. A special instruction set is available in order to establish a connection to a

PROMATRIX according to their corresponding application via the IRIS-Net PC software.

System DPM 4000 matrix manager. The two RS-232 ports can be configured

REMOTE CAN BUS

DYNACORD remote amplifiers and other devices with CAN

interfaces can be connected to the P 64 via the CAN

interface. Up to 100 remote amplifiers can be connected

with a single P 64. All connected components are linked to

the P 64 monitoring and control platform.

The STATUS-LED is provided to monitor the communication

on the CAN bus. If the CAN interface is not in use, the LED

is deactivated. In normal mode the LED flashes every 2 seconds. The duration of the flashing within these 2 seconds depends on the bus load. The higher the bus load is the longer the duration of the flashing within these two seconds will be.

Control Elements and Connections

CONTROL PORT

The CONTROL PORT contains four freely programmable

control inputs, three freely programmable control outputs,

one ready/fault output as well as reference connections for

ground, +5 V and +10 V.

The control inputs IN1 - IN4 are DC inputs, which internally

are connected to ground via pull-down resistors. From

external sources voltages between 0 V and +10 V are

possible. Either switch-mode functions or variable functions

can be programmed for the control input via the IRIS-Net PC software. Examples of use are: power on/standby switching, preset switching or parameter control.

The control outputs OUT2 - OUT4 are relay contacts, which are open circuits in off-state (off). When the output is in on-state (on) the outputs are connected to ground. The outputs are able to signal internal states and they can directly operate LEDs, indicator lights or relays. The +5 V reference voltage is able to energize the externally connected elements with up to 200 mA. Operating states (critical temperature, overstepping or falling below of defined limit values, faults, etc.) can be relayed to central operation stations or other systems (fire alarm systems, life safety systems) even without use of a PC via the control outputs. You will find detailed information regarding configuration of the control ports in the IRIS-Net documentation.

Mains Connector and Power Switch

Please use the enclosed power cable in order to connect

P 64 to the mains power supply. The P 64 is compatible with

a supply voltage between 100 V AC and 240 V AC.

Therefore, a supply voltage switch is not necessary.

Internally, there is a mains fuse which is normally only blown

in case of a fault. The fuse should only be replaced with an

equivalent fuse with identical values for current, voltage and

actuating characteristics by an authorized service center. The P 64 can be switched on and off with the power switch on the rear of the device. The ON-

LED on the front panel is immediately illuminated after switch-on. The P 64 boots and initializes all parameters with those values that had been previously active. The initialization takes some seconds. As soon as P 64 is ready for operation, the READY-LED is also illuminated.

You will find a program introduction in the online help of IRIS-Net and the corresponding quick start guide in the menu: > .

3.2 Installation of expansion cards

The options for expanding the P 64 controller through the use of expansion cards are explained in this chapter. The P 64 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, DO-1)

• 1 network module slot for the installation of a network mo dule, e.g. CM-1 CobraNe t™ Module

P 64 Digital Audio Matrix

Owner’s manual

Page 16

Preparations

• 1 DSP expansion module (DSP-1) for the expansion of the storage capacity and signal pro-

cessing

ATTENTION: It is essential to switch off the P 64 if you want to install or change a module. Y ou wil l 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 P 64 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

• DO-1 with 8 digital outputs

You can choose any slot for the installation of the expansion cards as the slot is automatically detected by the P 64 after the installation.

System expansion with a network module

An audio network interface for CobraNet™ can be installed in the network module slot on the rear panel of the P 64. 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 P 64 audio matrix 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 P 64 can be increased by installing the DSP-1 or DSP-2 DSP expansion module. This allows the execution of more complex DSP programs and the use of longer delay times or additional delay lines.

3.3 Interface description

Ethernet Interface

By connecting the P 64 audio matrix via the Ethernet interface, the communication between the P 64 and one or several PC is possible. This allows the configuration of P 64 via IRIS-Net software. Furthermore, the whole connected system (consisting of P 64s and DYNACORD Remote Control

Amplifiers) can be operated and monitored. By using appropriate network hardware it is even possible to operate the P 64 via a wireless network (WLAN). The Ethernet interface on the rear of P 64 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 t he following figure and table.

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 P 64 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.

If a crossover cable is used in order to connect a P 64 with a PC directly, pair 2 has to be interchanged with pair 3 on one side of the crossover cable. Thus, the necessary swap of the sending and receiving lines that is internally processed in a hub/switch takes place.

CAN Interface

The network for the DYNACORD remote power amplifiers is based on the CAN-bus standard, which has become widely accepted in the automotive, industrial and security sector. The CAN-bus is a balanced serial interface to transmit commands and data. 100 power amplifiers or other devices up to a maximum cable length of 1000 meters can be connected per CAN-bus.

Each bus member has 2 RJ-45 connectors for the remote CAN-bus. The connectors are connected in parallel and serve as input or output (for a

loop-through) of the remote network. The CAN-bus has to be terminated with a 120 Ω terminating resistance at both ends. Therefore, two terminating connectors CANTERM 120 Ω are included with the P 64. Please plug these terminating connectors in the free RJ-45 connectors of the first and the last device at the CAN-bus.

In addition to the CAN-bus, a balanced audio monitor signal is carried in the network wiring in order to monitor the input and output signals of all remote networks. This monitor bus makes it possible to monitor the input and output signals of all power amplifiers existing in the remote network via the software without the need for additional wiring work. At the P 64, the monitor bus can be gripped at a CAN connector (pins 7 and 8), it can be connected with an audio input and routed to a monitor box (e.g.) for monitoring purposes.

The CAN-bus makes it possible to use different data transmission rates, in which the boud rate is indirectly proportional to the length of the bus. If the network is only slightly extended, higher baud rates up to 500 kbit/s are possible. In case of larger extensions, the baud rate has to be lowered (to a min. transmission rate of 10 kbit/s). The following table explains the relationship between baud rate and length of the bus or extension of the network. In principle, bus lengths over 1000 meters should only be realized with repeaters.

USB connection

The USB interface on the front panel of the P 64 uses the USB 1.1 standard. Accordingly, the low speed (1,5 MBit/s) and full speed (12 MBit/s) transfer rates are supported. According to USB specifications, the cable which is connected to this interface must not be longer than 5 meters. The USB interface of the P 64 is a USBB (female) connector.

CONTROL PORT

The control port on the rear of P 64 is divided into two parts. Two Phoenix connectors (6-pin) are included in delivery in order to be able to connect external components.

Control Inputs

The upper part, which is marked as INPUTS 0-10V on the device, provides four freely programmable control inputs for voltages between 0 volt and 10 volts. The inputs are numbered in order from 1 to 4. The P 64 provides its own voltage supply for externaly connected monitoring elements, e.g. potentiometers or switches. The voltage supply is available at the 10V REF and GND connectors of the control port.

ATTENTION: The maximum allowable current at the 10 V REF is 100 mA.

The following figure shows an example application for the "analogue circuit" on the control inputs of the P 64. A voltage which can be changed via a potentiometer is connected at the control input

Control port with potentiometer

An example for a "digital circuit" on a control input of P 64 is shown in the following figure. The control input 2 is connected to ground via a switch (normally open contact). In IRIS-Net the P 64 can be so configured that, for example, an audio input or output channel can be muted by operating a switch. The threshold voltage for high/low which are used for this purpose are freely configurable for any input.

Control port with switch

Control Outputs

The lower part of the control port, which is marked as RELAY OUTPUTS on the P 64, provides different outputs. There are three freely programmable control outputs which are numbered in order from 2 to 4. These control outputs are designed as relays contacts (normally open), i.e. they are open when they are inactive (off) and closed towards ground when they are active (on). A voltage source at the 5V/200mA connection is available in order to operate the externally connected elements.

ATTENTION: The maximum allowable current at the 5 V output is 200 mA.

Preparations

The two left connections of the RELAY OUTPUTS are the READY/FAULT output of the P 64. This floating output is closed when the P 64 is ready for operation and no error has occurred. It is possible in IRIS-Net to configure which kind of error causes the contact to be opened. Due to this feature, this contact is especially suitable for the integration of the P 64 in life safety systems (closed current principle). An example application for the circuit of a control output is shown in the following figure. An operating state of the P 64 (e.g. the overstepping of a temperature limit) is indicated via a pilot light.

Analog audio connecting cable

It is advisable to choose balanced cables (2 signal conductors + shield) with XLR connectors as analog audio connections. Although all P 64 analog audio inputs and outputs can be used unbalanced, balanced audio cable is the better choice. A balanced differential audio circuit can prevent the injection of external noise into the audio path and is strongly recommended, particularly for long cable runs.

4.1 Introduction

The P 64 Matrix Manager can be connected to a TCP/IP-network via the Ethernet interface at its rear panel (see page 13). For further information on the principles of Ethernet and TCP/IP please see the chapter Ethernet principles on page 33 in the appendix of this document.

The P 64 comes with the following network configurations from the factory:

Parameter Value

IP address 192.168.1.100

Subnet mask 255.255.255.0

Gateway 192.168.1.1

DHCP deactivated

An IP address must be unique, it must only be allocated to one single device (host) in a network. In case a new Ethernet network is designed for the operation of the P 64, it is recommended to retain the subnet mask and network ID which had been set at the fa ctory. If t he P 64 is integrated in an existing Ethernet network, the network configuration of the P 64 must be adapted.

The preset IP address of the P 64 can be retained if and only if

• only a single P 64 with factory-set configuration is connected via Ethernet and

• the network ID 192.168.1 can be retained and

• no other devices have the Host-ID 100.

If at least one of these three conditions is not fulfilled, the preset IP address of the P 64 has to be changed.

Network configuration

Example:

The following illustration shows an example application with four P 64 in a closed network. These are networked with a PC via a central Ethernet switch. Thus, the factory preset IP address

192.168.1.100 would exist four times in the network. Because of this, the preset IP address of three P 64s must be replaced with a unique address.

Example of an Ethernet network with four P 64

It is advantageous and strongly recommended to list all devices used in the Ethernet network and IP addresses for changing the preset IP addresses of the P 64s. An example of such a list for the example system shown in the above illustration is given in the following. You will find an empty form in the appendix. Please enter the description of the device, an unambiguous description and the IP address which has to be assigned to the device for every device used in the network in this list. If the device is displayed in IRIS-Net, you can also use the description that is used there.

Device IRIS-Net Device Name Location/Description IP-Adresse P 64 main office main office 192.168.1.100 PC - main office 192.168.1.1 P 64 administration administration building 192.168.1.101 P 64 production production building 192.168.1.102 P 64 multi-purpose mult-purpose hall 192.168.1.103

When the example system is put into operation, the IP addresses which are given in the overview table, should be assigned to each device. The assignment of the IP address can be made via IRIS-Net and via the P 64 browser interface. In IRIS-Net the assignment is possible both over the USB interface and the Ethernet interface of the P 64. Information about the exact proceedings are given in the IRIS-Net online-help. For the assignment of the IP address over the P 64 browser interface open the browser interface using the current (preset) IP address of the P 64. Information about the exact proceedings are given in the P 64 browser manual.

5.1 Application Example

Installation in a multi-purpose hall

The following figure shows an example for the application of a P 64 Matrix Manager in a multipurpose hall. Four microphones, one CD player and one tuner are the connected signal so urces. Both active and passive speakers are used for the sound reinforcement. The ElectroVoice and DYNACORD Remote Amplifiers which are used for the operation of the passive speakers are connected with the P 64 via the CAN Bus in addition to the audio connections.

Two different methods are designed in order to operate and control the system. The first possibility is a conventional PC where the IRIS-Net (Intelligent Remote & Integrated Supervisio n) software is used to operate the P 64 and the remote amplifiers. It is not only possible to operate and control the system via IRIS-Net, but also to monitor the whole system. The P 64 and the PC are connected via Ethernet. Connecting a touch panel (e.g. AMX™, Crestron™) to the RS-232interface of the P 64 is the second possibility for the operation of the system. The desired functions of the system can be accessed via the special operating interface of the touch panel.

Appendix

Check Network Configuration of PC:

Check the network configuration of the used PC. Remember that the network part of the used IP addresses that is used and the subnet mask of the PC and the P 64 have to be identical.

Ruling Out Duplicate IP-Adresses:

It is possible that the same IP address is allocated twice if there are more devices in an Ethernet network and if the IP addresses are allocated manually. Switch off the P 64 and try to ping the IP address of the off-state P 64 via a command line prompt (see page 30 of this manual). If the ping is successful, another device has the address of the off-state P 64. In this case, change the IP address of the device which is now answering or of the P 64 with the duplicate address (then you also have to change the IP address of the P 64 in IRIS-Net).

Check Physical Connectivity Problems:

When the PC and the P 64 are connected physically via the Ethernet, the following points have to be checked:

• Is the network cable undamaged and plugged in correctly?

• Is - if necessary - a crossover cable used?

• Do the indicator lights of the network socket of the PC, the P 64 and (if available) of the network devices between the PC and the P 64 glow after the network cable(s) has/have been plugged in?

• Is a problem indicated on the used network interface in the system control devices of the operating system?

Connect directly:

Establish a direct connection between the PC and the P 64 via a crossover cable in order to rule out internal problems in the network devices between the PC and the P 64. If an IP address had been set up automatically (DHCP) via a network device which is now no longer connected, this address has to be set up manually again.

5.3 Ethernet principles

The P 64 matrix manager can be connected to an Ethernet network via the Ethernet interface (RJ-45) on the rear panel. Ethernet is a computer networking technology for local networks. It is possible to connect two devices (hosts) directly via a crossed Ethernet cable (crossover cable) if this is necessary. If more than two devices have to be connected, they have to be connected via normal Ethernet cables (straight through cables) and a central node (hub or switch). For this purpose the central hub or switch has an extension (port) for every network member. The Ethernet interface of the P 64 is compatible with the following Ethernet standards:

• 10Base-T (IEEE 802.3i): Four wires (two twisted pairs) of CAT-3 or CAT-5 cables are used for this connection. The transfer rate is 10 MBit/s and the maximal length of a segment is 100 meters.

P 64 Digital Audio Matrix

Owner’s manual

Page 34

Appendix

• 100Base-TX (IEEE 802.3u): Two twisted wire pairs are used for the connection (see above). However, in this case, a CAT-5 cable has to be used. 100Base-TX has a transfer rate of 100 MBit/s and is the standard Ethernet implementation nowadays.

IP addresses

Diverse network protocols can be used for the communication of the devices connected to the Ethernet network. The P 64 uses the TCP/IP protocol, thus, it is an IP network device. IP addresses are used for the logical addressing of devices in an IP network. The P 64 uses version IPv4 (Internet protocol version 4) for the addressing. Therefore, the length of an IP address is 32 bit (= 4 Byte). 4.3 billion unique addresses are theoretically possibl with this protocol. Normally IPv4 addresses are given in the dotted decimal notation, i.e. the four bytes are written as four decimals separated by dots. Thus, the general notation of an IPv4 address is AAA.BBB.CCC.DDD. An example of an IP address is 130.009.122.195. Zeros which stand in the first place can be omitted. That is the reason why the exemplary address can also be written as:

130.9.122.195.

The following table shows address sequences that should be used in private networks.

Class Adress space Subnet mask CIDR Number of IP addresses

A 10.0.0.0 -

10.255.255.255

B 172.16.0.0 -

172.31.255.255

C 192.168.0.0 -

192.168.255.255

Link local 169.254.0.0 -

255.240.0.0 172.16.0.0/12 1048576

255.255.0.0 192.168.0.0/16 65536

255.255.0.0 169.254.0.0/16 65536

Private IP addresses are especially of interest in networks which are connected to the Internet. Private IP addresses are not routed in the Internet. Thus, it is necessary to make an address conversion with NAT (Network Address Translation) or PAT (Port Address Translation = NAT and additional change of the port number) in order to be able to access the Internet. An benefit of this is that it is possible to connect several devices via a router with the Internet even when your Internet provider has only allocated one IP address. Additionally, the real IP address of the devices can be hidden from hackers by NAT/PAT (Security through Obscurity).

Subnet mask

An IP address is always divided into a network part (network address/ID) and a host part (host address/ID or device address). Devices are in the same network if, and only if, the network parts of their addresses are identical. Devices can interact directly with each other if they are in the same network. Ancillary equipment (e.g. a router) is necessary if devices in different networks should interact. Within one network host addresses may not be allocated twice.

P 64 Digital Audio Matrix

Owner’s manual

Page 35

Appendix

For example, a network could e.g. split the 4 Byte (32 bit) of an IP address in a 3 Byte long network part and in 1 Byte long host part. The exact partitioning between network part and host part is given in the form of subnet masks. In this case, the partitioning of the first 24 bits or the last 8 bits would be made because of the subnet mask 255.255.255.0.

The CIDR notation which is designed to display a subnet mask is an alternative to the dotted decimal notation. So called suffixes are used in the CIDR notation. The suffix indicates the number of 1-bits in the subnet mask. Thus, the subnet mask 255.255.255.0 in dotted decimal notation would correspond to the suffix /24 as the first 24 places (in binary description) of an IP address are chosen as network address.

It is possible to impact the maximum number of the devices addressable within a network by choosing the subnet mask which results in different partitioning of the IP address in network part and in host part. For the exact number it has to be considered that the host part may neither be completely zero nor completely 1 in the binary description.

Example: In case of the above-mentioned example IP address 130.9.122.195 the network part would be 130.9.122.0 by using the subnet mask 255.255.255.0. So, each device (or interface) in the considered network uses an address of the type 130.9.122.DDD. As the values 00000000 and 11111111 are excluded for the host part DDD in binary description, the corresponding decimal values 1 to 254 for DDD are allowed. Thus, a maximum of 254 different devices can be addressed in a network and the corresponding addresses are 130.9.122.1 to 130.9.122.254.

Automatic/Manual Allocation of IP Addresses

IP addresses can be allocated both automatically and manually to a device in a network. If the address is allocated automatically via DHCP (Dynamic Host Configuration Protocol), the operation of a DHCP server in the network is necessary. This server makes it possible to dynamically allocate an IP address and additional configuration parameter to hosts in a network. The use of a DHCP server is especially useful for networks in which devices are often connected and removed.

If DHCP is used, certain incidents (e.g. the reboot of a device) can result in the change of the IP address of this device. If this device is a P 64 matrix manager, its configuration in IRIS-Net has to be modified to reflect the changed IP address. For that reason it is not advisable to use DHCP for the dynamic configuration of P 64. Instead, of that the network configuration of the P 64 should be done manually.

When a new Ethernet network which will not be connected to the Internet is established, any network part of the IP addresses can be defined. By choosing the appropriate subnet mask it is possible to adapt the number of the addressable devices to your requirements.

Please contact your network administrator regarding details on the correct network configurations if one or several P 64 is/are integrated in an existing Ethernet network (with or without DHCP server) or if the network is connected to the Internet.

5.4 CAN-Bus Principles

The network topology used by the CAN bus is based on the so-called “bus or line topology”, i.e. all participants are connected via a single two-wire cable (Twisted-Pair cable, shielded or unshielded) with the cabling running from one participant on the bus to the next, allowing unlimited communication among all devices. In general, it does not matter if the bus member is a power amplifier, a P 64 or a UCC1 USB-CAN converter. Thus, the P 64 can be connected at any place of the CAN bus. In total, up to 100 devices can be connected to one CAN bus.

The CAN bus has to be terminated with a 120 Ω terminating resistor at both ends. If the termination is missing or an improper resistor value is used, network errors can occur as a signal is reflected on the bus at both bus ends. Because of the superposition of the reflection with the original signal, the original signal is blurred. This may result in the loss of data. In ord er to prevent or minimize reflections at the bus ends, terminators are used as they "absorb" the energy of the signal.

Since the CAN interfaces of all EVI Audio appliances are galvanically separated from the rest of the circuitry , network cabling also carries a common ground conductor (CAN_GND) ensuring that all CAN-interfaces in the network are connected to a common ground potential.

Bus Topology of the CAN bus

By using a CAN bus repeater a connection between two independent and self-contained CAN bus systems can be created. Thus, the following can be achieved:

• Increase of the max. number of members A maximum of 100 devices can be connected to one CAN bus. This number can be

increased up to 250 by connecting several CAN bus systems. This limitation of exactly 250 devices results from the addressing scheme used by the CAN bus. The addressing scheme allows the allocation of a maximum of 250 different CAN device addresses.

• Improvement of signal quality With CAN bus systems, whose bus length exceeds 1000 meters, a CAN bus repeater should

be used. The CAN bus repeater accomplishes a signal processing and a reinforcement of the

P 64 Digital Audio Matrix

Appendix

bus signals. The internal running time of the repeaters of approx. 150 ns corresponds to an extension of the bus over approx. 45 meters.

• Creation of alternative network topologies By using one or several repeaters, not only the above-mentioned bus topology, but the

creation of other network topologies are also possible. 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.

Performance Specifications

According to the ISO 11898-2 standard, CAN-bus data transfer cabling has to be carried out using Twisted-Pair cables with or without shielding providing a characteristic impedance of 120 Ω. Both ends of a CAN-bus need to be terminated with 120 Ω termination-plugs. The maximum bus-length depends on the actual data transfer rate, the kind of data transfer cable being used, as well as the total number of participants on the bus. The following table shows the most essential requirements for CAN-networks consisting of up to 64 participants.

Rate

* With longer cables and many participants on the CAN-bus, termination resistors with higher impedance than the specified 120 Ω are recommended to reduce the ohmic load of the interface drivers and therefore the voltage drop between the two cable-ends.

The following table is meant for first assessment of necessary cable diameters for different bus lengths and bus-participant numbers.

32 64 100

Number of Units on the CAN-Bus

Additionally, the length of branch lines - for participants that are not directly connected to the CAN-bus - is also of importance. For data transfer rates of up to 125 kbit/s, the maximum length of a single stub cable should not exceed 2 meters. For higher bit rates a maximum length of only

0.3 meter is still permissible. The entire length of all branch lines should not exceed 30 meters.

General Note:

• As long as only short distances (up to 10 meters) are concerned, common RJ-45 patch cables with a characteristic impedance of 100 Ω (AWG 24 / AWG 26) can be used for the cabling inside of a rack mounted system.

• The previously outlined guidelines for network cabling are mandatory as far as the rack mounted shelve interconnection or fixed installations are involved.
