5. Installation

5.1. Location, assembly and ventilation

MIMO7272DN has been specially designed to be placed in 19" rack structure, occupying one unit.

It is very important that, as a heat generating element, MIMO7272DN is not completely enclosed or exposed to extreme temperatures. Fresh air should be allowed to pass through the ventilation holes in the chassis, leaving at least one free rack unit between each piece of equipment and those installed above and below it in the rack frame.

If the installation consists of several amplifiers in the same rack or is carried out inside cabinets closed by means of doors, it is highly recommendable to equip them with forced upward ventilation, installing fans at their lower and upper ends. This upward flow of ventilation will favour the dissipation of the heat generated in its interior.

5.2. Mains connection and power on

MIMO7272DN operates on alternating voltages from 90 to 264V and 47 to 63 Hz. This device is equipped with an oversized power supply capable of adapting without any type of adjustment to the mains voltage of any country in the world.

On the rear panel, next to the IEC power connector, there is an on/off switch for the unit. On the front panel there is an LED indicator that illuminates when the unit is in operation.

Do not allow the network cable to run parallel to the shielded cables carrying the audio signal, as this may cause humming.

5.3. Balanced analog audio inputs

MIMO7272DN has on its rear panel 8 analog signal inputs (IN 1 to 8), balanced and supporting line or microphone levels. The selection of the input signal type and its management is done from the EclerNet Manager application. Refer to the EclerNet Manager Application manual for more information.

The signal input connectors are Euroblock type. The assignment of the connection is as follows:

• Live or direct signal > Terminal +
• Cold or inverted signal > Terminal -
• Ground > Terminal ⊥

For UNbalanced connections, short-circuit the terminal - to earth.

5.4. Balanced analog audio outputs

The rear panel of the MIMO7272DN has 8 analog signal outputs (OUT 1 to 8) and 2 additional "MONITOR" monitoring outputs, balanced and with line level.

The signal output connectors are Euroblock type. The assignment of the connection is as follows:

• Live or direct signal > Terminal +
• Cold or inverted signal > Terminal -
• Ground > Terminal ⊥

For UNbalanced connections, leave the terminal - unconnected.

5.5. Digital audio inputs and outputs over IP DANTETM/AES67

(Ports for primary and secondary networks)

MIMO7272DN allows the reception of 64 channels of digital audio DANTETM/AES67 and the sending of 64 channels of digital audio DANTETM/AES67 through an Ethernet network compatible with the transport of digital audio over IP through the DANTETM/AES67 protocol.

The routing of the digital audio signals DANTETM/AES67 through the Ethernet network, as well as the network configuration of the ports DANTETM/AES67 (IP addresses, mask, etc.) of the MIMO7272DN, is managed by the software application Dante Controller. For more information, please refer to the developer's documentation: https://www.audinate.com/products/software/dante-controller

MIMO7272DN features two ports with RJ45 interface in its rear panel that allow the sending and reception of digital audio DANTETM/AES67, labelled as primary (PRIMARY) and secondary (SECONDARY). MIMO7272DN can work with these ports in two possible modes:

• Redundant Mode: there are two simultaneous network connections (each with its own IP address, both different) so that the information Ethernet packets DANTETM/AES67 are transmitted via both connections. Each port (primary and secondary) must be connected to a different physical Ethernet local network, or to a different virtual local network (VLAN), correctly configured and isolated from each other. The digital audio DANTE™™/AES67 is therefore sent and received using two distinct and independent paths, with no possible communication between the primary and secondary ports. In case one of them fails, MIMO7272DN will automatically switch to the other, recovering the audio transmission almost instantaneously. Obviously, to achieve total redundancy, all DANTE™™/AES67 devices that are part of a system of this type must have primary and secondary DANTETM/AES67 ports, connected respectively to the same two independent networks as MIMO7272DN.

Note: in this mode, if (by mistake) the primary and secondary ports connect to the same Ethernet network, Dante Controller will no longer have access to the network configuration control and routing DANTE™™/AES67 of the MIMO7272DN ports. This control is recovered when one of them is disconnected from the same network as the other.

Note: DANTETM/AES67 redundancy requires that the primary and secondary ports of all DANTE™™/AES67 devices connect using the same network connection speed. For example, if the primary port connects to a network with a 1 Gbps link, the secondary port must also connect at 1 Gbps.

• Switched mode: in this mode, only a single network connection is actually enabled (and therefore only one IP address exists), with the primary and secondary ports behaving as ports of a network switch integrated within MIMO7272DN, to which devices forming part of the system's DANTETM/AES67 network, or Ethernet switches forming part of that network's infrastructure, can be directly connected.

Note: in this mode both ports primary and secondary, should never be connected simultaneously to network switches, as this would create a loop that would cause network conflicts and disruption of the digital audio DANTETM/AES67 traffic.

5.6. Programming and control Ethernet port

The RJ45 connector labelled ETHERNET allows the connection of the equipment to an Ethernet local network (LAN), being compatible with the following purposes:

• Management from the EclerNet Manager application, by direct connection (CAT5 cable or higher) of a computer with a MIMO7272DN unit or using an Ethernet network as a link between both. Refer to the EclerNet Manager Application manual for more information.
• Connection to third party control equipment. (Crestron, AMX, Extron, Medialon, etc. are registered brands from their respective owners). Protocol used: Ecler TP-NET. Refer to the TP-NET PROTOCOL chapter for more information.
• UCP: EclerNet project remote control service using customisable graphical control panels. MIMO7272DN can act as a server for these panels, included in an EclerNet project, and also be remotely controlled by UCP panel client devices (WPNETTOUCH, Android® or iOS® mobile devices, Windows® devices, etc.).

5.6.1 Factory Preset Network settings

The factory default network settings for EclerNet Manager compatible devices are as follows:

• IP: 192.168.0.100
• Mask: 255.255.255.0
• Gate: 192.168.0.1
• UDP Port: 2210

5.7. Control remote RS-232 port

The RS-232 port with DB9 connector built into the rear panel allows an external device to communicate with a MIMO7272DN unit via serial connection. This connection will use the syntax of the TP-NET protocol so that the external device can obtain the value of some of the parameters of the MIMO7272DN unit (by means of "GET" commands) and/or modify these values ("SET" commands). Refer to the TP-NET PROTOCOL chapter for more information.

The serial connection must comply with the following characteristics:

• Baud rate: 115200 (fixed, no auto negotiation)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None

5.8. Remote control GPI ports

The MIMO7272DN rear panel has 8 GPI inputs for direct voltage control, 0 to 10 VDC. Each of these inputs can be connected to an external physical device (a potentiometer, a contact closure, a variable 0-10V DC voltage, etc.) and associated with a MIMO7272DN function, for example:

• Remote control of an input channel volume, output or matrix crossover using a physical potentiometer or a remote control WPa series from Ecler.
• Activation / deactivation of a MUTE or SOLO by means of a push-button or contact closure.
• Retrieval of a preset by means of a pushbutton or contact closure.

The GPI connectors are Euroblock type. The assignment of the connection is as follows:

• Positive, + 12 VDC > Terminal +
• Variable voltage, 0-12 VDC > Terminal ↑
• Ground > Terminal

Jumpers position: ALOG / LIN → LIN position, +12/+10 → +12 position

WPaVOL connection to MIMO serial GPI ports

Jumpers position: ALOG / LIN → LIN position, +12/+10 → +12 position

WPaVOL-SR connection to MIMO serial GPI ports

5.9. Remote control GPO ports

MIMO7272DN has on its rear panel 8 relay outputs NO / NC (normally open / normally closed). Each of these outputs can have its status change associated with a trip by means of a specific function programmed through EclerNet Manager, such as a calendar event or the pressing of a key available on a UCP control panel. In this way, it is possible to interact with external equipment, such as motors for projection screens or movable partition walls, lights, sirens, GPI inputs from other equipment, etc.

The connection cables can be up to 500 meters approximately, using a minimum cross-section of 0,5 mm².

Consult your ECLER distributor or at www.ecler.com about the serial remote-control wall panels WPa series and other accessories available for connection to REMOTE / VCA ports.

6. Observations

6.1. Ground loops

It must be ensured at all times that the signal sources that reach the matrix, as well as all the devices that are connected to its output, do not have the grounds interconnected, that is to say that the grounds never reach them by two or more different paths, since, in this way, buzzes could be produced that would even interfere with the quality of the sound reproduction.

The shields of the cables, if they are connected to a chassis, must never be connected to each other. This way we avoid the formation of ground loops.

6.2. Background noise

MIMO7272DN has been designed to obtain the lowest possible background noise. Regardless of the electronic design, the background noise will depend directly on the correct use and installation of the unit.

It is not the same, for example, to have the GAIN control of a channel at 2 and the VOL of the output to which it is routed at maximum (case 1), to have a correct gain setting on the input signal and the VOL level of the output channels to which it is routed at an intermediate position (case 2). In the first case, the signal that reaches the mix amplifier, which intrinsically has its own background noise level, is weak, so the signal-to-noise ratio is low (low signal). When the output amplifier raises indistinctly the whole set we will have a very high background noise level at the output.

In the second case, when the input gain is correctly adjusted, the signal received by the matrix is large and therefore with a large signal / noise ratio as well, so when this signal reaches the output channels and is amplified, it will have a better ratio than in the previous case.

Processing

12. TP-NET Protocol Introduction

The TP-NET protocol lets a client device (control device) get and/or set the values of several parameters of the EclerNet compatible devices (MIMO and MIMO SG series digital matrices, DUO-NET PLAYER, NXA digital audio manager series, NZA amplifier series, NPA amplifier series, etc.), like volumes, mutes, alarms, etc. It's as well available for eMIMO1616 digital matrix, HUB series digital zoner, MIMO7272DN and MIMO4040CDN digital matrix.

The communication with these digital audio devices can be established using Ethernet and the UDP/IP transport protocol, always by means of the 5800 UDP port.

A second option for this communication is using the RS-232 interface that some of these compatible devices do also have (MIMO series, DUO-NET PLAYER, NXA series, etc.). In this case, the serial connection must fulfil the following specifications:

• Baud rate: 57600 (fixed, no autonegotiation) for all the devices, except for DUO-NET PLAYER, eMIMO1616, HUB series and MIMO4040CDN, which use 115200 baud rate)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None

In case the Ecler device has an Euroblock connector for the RS-232 interface, the serial cable wiring, from the device's connector to a standard DB9 serial interface connector, must be the following:

The protocol is simple and direct, making it easy to read, write and modify the generated code. It is based on messages with no begin and end delimiter: each message is self-delimited by the UDP packet size, which is defined with a maximum of 80 characters. All the messages must be written in capital letters.

To let some control systems (like CRESTRON®, EXTRON®, AMX®, RTI®, VITY®, MEDIALON®, etc.) process the messages more easily, the EclerNet device adds the character LF (0x0A) to the end of each message. This way the client can buffer the messages to process them, if it's required. The EclerNet device can also handle several messages received in a single message packet by using the LF delimiter.

The available messages are built with one or more fields separated with blank spaces ( = blank space):

<TYPE> [PARAM1] [PARAM2] [PARAM3] [PARAM4][LF]

The first field (TYPE) defines the message type and then, the required parameters for it (each kind of message requires a given number of parameters). The field TYPE can have these values:

• SYSTEM
• GET
• SET
• INC
• DEC
• SUBSCRIBE
• UNSUBSCRIBE
• DATA
• ERROR

At the end of this document you'll find all the available messages and their parameters for each model of the EclerNet compatible devices.

The SYSTEM, GET, SET, INC, DEC, SUBSCRIBE & UNSUBSCRIBE messages can be sent from the client to the EclerNet device. The DATA & ERROR messages can be sent from the device to the client. The only exception is the SYSTEM PING message, that is a SYSTEM type message that is sent from the EclerNet device when the initial message from the client to the device was SYSTEM CONNECT PINGPONG.

The communication (using UDP or RS-232) starts when a client sends the message SYSTEM CONNECT to the EclerNet device. As far as the UDP communication requires no connection (unlike the TCP), the EclerNet device stores this client's IP address, and then uses it as the destination IP address for the messages that it generates (DATA & ERROR). After receiving the SYSTEM CONNECT message, the device dumps its entire configuration using several consecutive DATA messages.

Note: if the configuration data dump process (usually a huge list of parameters & values) wants to be avoided after a SYSTEM CONNECT message, a SYSTEM CONNECT ONCE message can be used instead.

The communication can be terminated by two methods:

• Manually: when the client sends the SYSTEM DISCONNECT message, cancelling all the subscriptions and stopping the DATA & ERROR messages.
• Automatically: in case the initial message was SYSTEM CONNECT PINGPONG and the client didn't get any SYSTEM PONG message in a period longer than 10 seconds (presuming a communication breakdown).

The SET messages don't have an automatic acknowledgement with a DATA message sent from the EclerNet device after it has processed the SET command. The client must update the values itself and must send the needed GET message if it requires confirmation from the device.

NOTES:

• The numerical values are always integer numbers without +, −, comma or dot symbols.
• [PINGPONG] is an optional parameter used to configure the device-client communication with a periodical check, to see whether the client or the device have terminated it. When configured this way, the device sends a SYSTEM PING once per second, and the client must answer with a SYSTEM PONG message. If anyone doesn't get these messages along a 10 seconds period, the communication will be considered terminated.
• [ONCE] is an optional parameter used to start the device-client communication without a full data dump process (usually a huge list of parameters & values).
• <Input Channel> & <Output Channel> are numerical values that identify an input or output channel of the EclerNet device. It can be within a [1...40] range for MIMO7272DN.
• <Preset Number> is a numerical value that identifies one available Preset stored in the EclerNet device's memory.
• <Level>, <Pre Vumeter Level> y <Post Vumeter Level> are numerical values in the [0..100] range that define values in a scale equivalent to [-inf..0] dB.
• <GPI> & <GPO> are numerical values within the [1..8] range for MIMO7272DN.
• <GPI Value> is a numerical value within the [0..100] range that indicates the value of an analogue GPI input. For a digital input only 0 or 100 are the possible values.
• <GPO Value> is a numerical value within the [0..1] range: it can only be 0 or 1 (opened or closed GPO).
• <Rate> is a numerical value within the [1..10] range that sets the VU-meter refresh rate, or the number of times the vumeters' values are sent per second (by default = 3).
• "<Device Name>" is the device name inside double quotation marks, to allow for names with blank spaces.
• <Error ID> is a numerical value for an error code.
• "<Error Description>" is a text chain inside double quotation marks, containing an error description.
• <Virtual Control> is a numerical value that identifies a Virtual. It can be within a [1..160] range for MIMO7272DN model.

13. MIMO 7272DN Digital Matrix

IMPORTANT NOTE: The communication must be started with the client sending the first message SYSTEM CONNECT or SYSTEM CONNECT ONCE to the EclerNet device. Otherwise, the commands from the client to the EclerNet device will be ignored. See TP-NET PROTOCOL INTRODUCTION chapter for additional information.

Note: INC and DEC commands are replied with a DATA command from the device with the resulting LEVEL value, after it has been increased or decreased. When the INC or DEC command tries to adjust a LEVEL value beyond its minimum or maximum limits, no reply (DATA command) will be produced.
