Device Description

Congratulations on your purchase of a DD4MR-FX Optical Digital Network Device with Cat5 based SANE, MADI,
video Ethernet and data interfaces. The DD4MR-FX manual will quickly demonstrate the advantages of the
device and help to ease your day-to-day workload in a professional audio-visual environment.

The DD4MR-FX is a digital I/O unit and interface to the OPTOCORE and SANE DIGITAL NETWORK
SYSTEM. The unit provides two coaxial MADI input and two coaxial MADI output ports, allowing the transmission
of up to 128 input and 128 output digital audio channels. Device can operate in sample rates up to 192 kHz
(sample rates above 96 kHz are available upon request). Each MADI port can be adjusted by OPTOCORE
CONTROL software to handle different formats according to the standards AES10-1991/AES10-2003. BNC
coaxial cables are used at the MADI ports. It is perfectly suitable for 3rd party equipment integration, especially
with AVID and DiGiCo digital consoles as well as recording and playback machines.

Redundant fibre Optocore connections can be established using the two provided SFP-based LC multimode or
singlemode optical LINK-interfaces. The dual redundant ring structure provides maximum safety in a network with
an outstanding low latency. It facilitates the use of the advantages of fibre optical transmission in all sorts of
temporary and permanent applications, especially when long distance connections and high-quality audio are
required.

The DD4MR-FX enables connectivity to the SANE network via RJ45 ports. It is possible to use SANE as a Cat5
based cost-efficient extension to the optical core system. SANE ports may be used as point-to-point MADI over
Cat5 or as a bridge interface between SANE and OPTOCORE, providing in total up to 128 input and 128 output
additional channels.

Two built-in Ethernet ports can be used to establish 100Mbit Ethernet LAN through the OPTOCORE and SANE
networks. The DD4MR-FX together with R-Series devices, YG2 and DD6NE behaves like one 100Mbit Ethernet
switch. SANE ports can be used for Ethernet transport as well, so up to four ports can be used to provide Local
Ethernet connection via single DD4MR-FX.

The DD4MR-FX provides both word clock input and output. It includes also bi-directional composite video
interfaces. Additionally four RS485 ports allow the transport of a wide range of standards such as RS422, DMX,
MIDI, and CAN-Bus (bi-directional, requires special firmware version). In addition to the audio signals, video and
data signals are transmitted through the common fibre connection. The dual power supply unit, with automatic
switchover, permits a redundant power supply and safeguards against malfunctions in the event of a power
supply failure.

The DD4MR-FX is the perfect I/O unit for a wide range of professional audio devices with MADI inputs and
outputs such as digital consoles and I/O systems. The high number of channels exchanged by one DD4MR-FX
makes it the ideal and most cost effective interface for digital console systems. The number of input channels can
be defined in groups of eight by the OPTOCORE CONTROL software. Only this number of channels is allocated
for transmission via fibre optical connection. This keeps the system highly flexible in order to build the network
exactly suiting the application needs. A DD4MR-FX, for example, can transmit 128 channels to a digital console
system from various Optocore devices such as DD32R-FX, X6R-FX or V3R-TP. If only eight return channels from
the console are required, only those eight channels instead of 128 inputs can be received at the DD4MR-FX and
transmitted via fibre optical connection, leaving the other channels to be shared by the other network devices.
Networks with several DD4MR-FX and other Optocore devices allow the transport of a huge amount of digital
data, e.g. 768 audio channels with a sample rate of 48 kHz, 32 RS485 channels and three video channels.
Depending on the type of fibre optic transceiver, distances from 700 m up to 120 km can be covered.

The dual optical interfaces with data transfer rates up to 2 Gbps are equipped with LC-connectors, commonly
used and absolutely reliable in permanent installations. For rough applications such as touring and live
productions the 1U OptoCon panel, with rugged and secure fiber optic connectors can be added to the rack.

All Optocore devices are designed and built using the latest programmable microprocessors and FPGA (field
programmable gate array) logic circuitry. This allows the devices internal logic to be updated, in the field, ensuring
a continual state-of-the-art device.

Optocore devices, and complete networks, are configured and operated using the OPTOCORE CONTROL
software. The software provides access to all configuration parameters and controls needed to operate the
system, including: naming channels, setting gains and phantom power, routing as well as recall and capture of
partial or full system configurations. The software can be operated offline as well as online with level meters for all
channels on the network.

Device Details

Optocore Fibre Optic Connection

The device is equipped with the Optocore FX communication module. The OPTOCORE ® OPTICAL DIGITAL
NETWORK SYSTEM utilizes Time Division Multiplex technology (TDM) with a Fibre Channel based 8B10B-NRZI­coding. Static time slots guarantee a synchronous transmission of all channels, at all times, without the use of
dynamic bandwidth or latency. All signals connected to the intercom, audio, video, word clock and auxiliary ports
of the device are transmitted simultaneously on one fibre while the second fibre of the LINK-Interface receives
data from the network. The second LINK-Interface pair is identical to the first one, and can optionally be used for
network redundancy.

MADI Ports

MADI (Multichannel Audio Digital Interface) was first standardized by the AES10-1991 for the transmission of 56
digital audio channels in one frame. The revision AES10-2003 enhanced the number of channels to maximal 64
digital channels. The DD4MR-FX supports the formats according to both standards. If an external device cannot
handle a 64 channel MADI frame the ports can be set to the ‘older’ AES10 standard with OPTOCORE
CONTROL.

The DD4MR-FX is equipped with two MADI input ports and two MADI output ports, each transmitting or receiving
up to 64 audio channels. This amounts to a total number of up to 128 input channels and 128 output channels per
device. The interfaces are BNC connectors..

The number of input and output channels exchanged at each port and transmitted on the fiber optical connection
can be defined with OPTOCORE CONTROL. This keeps the matrix easy-to-handle and the quantity of channels
per device in the network flexible. Using one DD4MR-FX does not automatically mean that 128 channels are
allocated on the fiber connection. The user is free to decide how many channels are needed for the transport of
MADI in groups of eight. LEDs on the front panel of the DD4MR-FX indicate the number of channels received at
the MADI input ports. The MADI output ports always transmit the complete frame with 56 or 64 audio channels
according to the standard. The inactive channels have all bits set to zero.

SANE Ports

The device is equipped with two RJ45 200MBit SANE Ports, capable of transmitting 64 channels of synchronous
audio and 100MBit Ethernet. SANE 2 port is compatible with MADI over Cat protocol.

RS485 Auxiliary Ports

The auxiliary ports provide four RS485 interfaces to establish a maximum of four half-duplex or two full-duplex
connections between the devices. A wide range of bi-directional and unidirectional standards can be connected,
such as RS485, CAN-Bus (bi-directional, requires special firmware version), or RS422, DMX, MIDI
(unidirectional). The ports automatically sense whether they are sending or receiving control data.
The ports and their destinations are configured in the OPTOCORE CONTROL software.

Word Clock

Devices with Optocore/SANE modules are equipped with an internal, high quality, low jitter clock generator as
well as Word Clock inputs and outputs. Any device on the network can act as the master of the network and pass
Word Clock to networked Optocore/SANE devices.

The internal/networked Word Clock is available at the Word Clock output connector of each device on the network
to synchronize non-networked devices.

In standalone network configurations external synchronization is not required.
The Word Clock input termination can be switched on using the OPTOCORE CONTROL software’s Local

Settings. External termination is not required to avoid cable reflections.
Word Clock master negotiation after any Word Clock source failure is done automatically

Video Ports

A video in- and output is integrated for the transmission of composite video signals. Up to three video channels
can be transported through the Optocore network depending on configuration.

Ethernet Ports

DD4MR-FX supports Optocore and SANE Ethernet transport. Two LAN interface with all other LAN and
SANE/LAN ports in the Optocore and SANE Network creating a large unmanaged virtual 100Mbit Ethernet switch.

DD4MR-FX

rev. 2.1

Power Supply

The device is optionally equipped with two power inputs and power supply units. If one power supply fails, due to
malfunction of the feeding power line or the power supply unit itself, the device will automatically switch over to
the other power supply unit. In order to make the power supply redundant, both power inputs must be connected
to the mains supply, if possible to different phases, power supply systems, or even better, one of them to an
uninterrupted power supply (UPS).

The power supply units operate with mains voltage of 100 ... 240 V and frequency of 50 … 60 Hz. Thus the
device can be used throughout the world without any modifications or transformers.

Transmission Delay

The Optocore system delay including the matrix is fixed to 41,6 µs @ 48 kHz for all channels. The additional
transport delay per Optocore unit (<200 ns) in the network is insignificant in comparison. Overall system delay is
dependent on the converters used and the length of network cables in the system. Assuming ‘normal’ cable
lengths of <700 m per link, the additional delay is considered marginal.

The transmission delay is constant between any points in the network.

Control

All system and device parameters are configured using the OPTOCORE CONTROL software.
The system can be configured and controlled centrally, over the Optocore network, with the exception of the initial
configuration of the unique identifier (ID) of the device.

The OPTOCORE CONTROL software is capable of running multiple instances on the same PC or by using the
OPTOCORE CONTROL software’s Client/Server mode.

Optocore bandwidth allocation

The standard bandwidth allocation of an Optocore network is as follows:

Audio

256 Channels @ 48 kHz – 1 Gbit network
768 Channels @ 48 kHz – 2 Gbit network

RS485 Data 32 Channels
Video 3 CVBS Video Channels *
Ethernet 100 MBit Fast Ethernet *

* If the network is used for transport of Ethernet compatible data the capacity is reduced to one CVBS video
channel plus 100 Mbps Fast Ethernet.

Please note:

Optocore R-Series devices equipped with 2Gbit fibre transceivers are required for
2Gbit network operation.

Please note:

Please refer to the Optocore Quick Start Guide for the basic system configuration and
setup.

For more detailed setup please refer to the Optocore Software Manual

Important:

The switched-mode power supplies operate at very high voltages.
Coming into contact with the power supplies can lead to considerable electric shock,

which may result in death.
To prevent electric shock, do not remove any covers of the device.

simply by "daisy-chaining" the units and monitoring the three status LEDs of each device, as revealed through the
signal flow in diagram below. There is no need to worry about the sequence of neither IDs nor which of the two
LINKS of a device is used for connection. The only condition is that an optical input must be connected to an
optical output. During the self-configuring of the network the system word clock master will be automatically
determined as indicated down under Optocore Network Setup – General . If the DD4MR-FXs and other Optocore
devices are previously configured, the network is ready to work. With a PC connected to any unit in the loop and
by running the OPTOCORE CONTROL software, the network may be analyzed, supervised, parameters may be
changed and the matrix can be accessed for signal-routing.

A second redundant reverse loop can be additionally created with only one more connection from the last unit of
the chain back to the first, as demonstrated by the signal flow diagram in Fig. 2.

Fig. 2: A redundant network with one DD4MR-FX unit

In case an interruption occurs at position “a” as illustrated above, this will only result in a loss of redundancy. This
also applies to the very unlikely case of a device failure. The redundancy of the ring can be reestablished simply
by connecting the in and out fibre with the help of an adapter and a new device can be integrated at any time.

Network Examples

DD4MR-FX devices can be used as a fibre optic extender for BNC MADI based devices or as a extender for
consoles which use BNC based MADI (e.g. AVID – requiered special firmware version). Configuration below
shows how to transport MADI stream from console or other MADI interface to remote located recording system
using redundant fiber connection.

Connection diagram below shows how to use OPTOCORE devices as a I/O for 3rd party producers consoles.
DD4MR-FX can pick up the channels directly from the stage and integrate them with the console using BNC
MADI connectivity.
