V3R-FX-INTERCOM-IC444 with 4Line Level inputs and outputs, 4GPIO and an auxiliary power output.
The IC422 and IC485 provide four-wire intercom ports with line level audio inputs and outputs along with serial
data links on RJ45 connectors for communication between intercom matrices and auxiliary devices.
Serial control is routed with the audio, requiring audio to be routed to and from each port in order to establish bi-
directional audio and serial communication between matrices, user key-panels and/or interfaces.
The ICAES provide four-wire intercom ports with AES/EBU audio inputs and outputs with control embedded on
RJ45 connectors for communication between intercom matrices and auxiliary devices.
Each IC422 and IC485 four-wire intercom port can be used as an independently routed line level input / output
using an adaptor from RJ45 to a connector such as XLR. ICAES intercom’s AES I/Os can be used as
independent digital inputs and outputs with special RJ45 adapter.
The IC422, IC485 and ICAES RJ45 four-wire intercom ports are duplicated with reversed wiring so that either
matrices (TO MATRIX) or intercom key-panels (TO PANELS) can be connected to the unit using standard CAT
cables, making cabling simple and cost-efficient.
The IC444 provides line level audio inputs and outputs, GPIO (General Purpose Inputs and Outputs) and auxiliary
+5V DC and +12V DC power outputs, to power external circuits, on 37 pin D-Sub connectors.
GPIOs are routed with the corresponding audio inputs and outputs, requiring audio to be routed to and from each
port in order to establish bi-directional audio and GPIO link.
What do the product names refer to?
V3 refers to the channel capacity of the device. Where V is the Roman 5: 5+3=8.
X6 refers to the channel capacity of the device. Where X is the Roman 10: 10+6=16.
Rrefers to the Optocore Revolution series hardware platform.
FX specifies that the device is equipped with Optocore fibre connectivity.
IC422/IC485/ICAES/IC444: specifies the connectivity option of the device.

X6R/V3R-FX-INTERCOM 12 / 33 rev. 2.8
The low latency, synchronous, Optocore network provides the capacity to transport and route up to 1024 audio
inputs into thousands of outputs over a redundant network. Redundant fibre connections are established using
the two LC multimode, or single mode, 1Gbit or 2 GBit optical transceivers. The dual redundant ring topology
uses the advantages of fibre optical transmission in temporary and permanent applications, especially where long
distance transport and high-quality audio are required.
Additionally, the Optocore FX module includes 64 channel SANE synchronous audio ports on Cat5 connectors
with Ethernet, 4 RS485/422 ports, 100Mbit Ethernet switch and a Word Clock input and output.
Extensive networks of Optocore FX devices and SANE TP devices can be created using devices with different
connectivity options to route and transport intercom, audio, serial data, composite video and Ethernet.
Word Clock input and output connectors allow the Optocore network to be synchronized from an external source
as well as for Word Clock be distributed around a facility using the Optocore network. All Optocore and SANE
devices are capable of being system masters using their internal clock.
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.
The X6R/V3R-FX-INTERCOM units can be operated and controlled via the OPTOCORE network with
OPTOCORE CONTROL software without the need for any external data cable. For control in stand-alone
applications, LAN, USB or RS232 ports on the front / rear panels can be used.
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.
The X6R/V3R-FX-INTERCOM is designed for rack-mounted applications.
The LEDs on the front panel of the X6R/V3R-FX-INTERCOM units allow an instant overview on the status of each
channel, indicating if audio is present, if peak level is reached and if nothing is routed to an output.

Device Details
IC422 and IC485 - Intercom Ports
Each four-wire intercom port is complete with a line level input, line level output and a bi-directional RS422 or
RS485 (device specific) serial communication link, allowing seamless integration with Clear-Com or RTS intercom
systems.
The intercom ports are duplicated with a reversed pinout (TO MATRIX and TO PANEL) to allow connections to
intercom matrix frames, user key-panels and interfaces using straight Cat5 cables.
ICAES - AES3 Duplex Ports
Each duplex port provides one fully 32-bit transparent AES3 input and output on a single RJ45 connector,
allowing seamless integration with AES-based intercom systems. Intercom matrix and INTERCOM-ICAES
devices must synchronise to the same system clock.
IC444 - Line Level I/O and GPIO
The IC444 module is populated with 37 pin male and female D-Sub connectors. The female connector has 4 line
level inputs and 4 optically isolated General Purpose Inputs (GPI). The male connector has 4 line level outputs 4
General Purpose Outputs (GPO). Auxiliary +12V DC and +5V DC power is available on both connectors, allowing
up to 100mA of current to be drawn from each IC444 module. The V3R-FX-INTERCOM unit can be equipped with
one IC444 module, while X6R-FX-INTERCOM can be equipped with two IC444 modules.
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-NRZI-
coding. 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.
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
The auxiliary ports provide four RS485 ports to establish a maximum of four half-duplex or two full-duplex
connections between devices. A wide range of bi-directional and unidirectional standards can be connected to the
ports, such as RS485, CAN-Bus (bi-directional, requires special firmware version), or RS422, DMX and 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.
Transmission Delay
The Optocore system delay, including the matrix, is a fixed 41,6 µs @ 48 kHz for all channels. The additional
transport delay per Optocore unit on the network (<200 ns) 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.

X6R/V3R-FX-INTERCOM 18 / 33 rev. 2.8
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.
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 Ethernet transport the system is reduced to 1 CVBS video channel.
SANE bandwidth allocation
The standard bandwidth allocation of a SANE link is as follows:
Audio
64 Channels @ 48 KHz
Ethernet
100 MBit 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.

connectors.
Connect intercom matrix to ports labelled TO MATRIX and intercom user key-panels and interfaces to ports
labelled TO PANEL.
Optical Connections
Multimode transceivers connected using a 50 µm OM3 fibre cable can be used for applications requiring cable
lengths of up to 700 m (worst case).
Single mode transceivers connected using a 9 µm fibre cable can be used for applications requiring cable lengths
of up to 70 km (worst case).
The total optical loss should be less than 6dB between transceivers.
For portable applications, such as touring and other temporary installations, ruggedized HMA Expanded Beam
Connectors, mounted on 1 RU panels and portable cables on cable drums are available.
Please refer to the Product Brochure available at www.optocore.com.
SANE Ports
Use standard, fully wired, twisted pair cable (Cat 5, Cat 5e, Cat 6) terminated with RJ-45 connectors. SANE
utilizes all four pairs of the Cat 5 cable, two pairs for standard Ethernet transmission and two pairs for the SANE
synchronous audio transport. A SANE cable shall not exceed a total cable distance of 100 m.
Auxiliary Ports – R485/GPIO
Each of the four channels requires a shielded twisted pair cable.
If two or more channels are wired to the same cable, a common braided shield should enclose the pairs.
RS232 Connection
Use a standard shielded RS232 cable.
Connector Hood Specification
Locking screws for D-Sub connectors should be compatible with 4-40 UNC. Care should be taken in selecting the
right type of connector hoods in order to fulfil the requirements of EMI-radiation directives. Full metal connector
hoods should be used, approved acc. to VDE 0871, FCC 20780 and EMC directive 2004/108/EG, providing
attenuation > 40 dB between 30 MHz up to 1 GHz. The shield of the cable should have contact to the connector
hood.
USB Connection
Use a USB-A to USB-B cable between the PC and the Optocore device.

X6R/V3R-FX-INTERCOM 20 / 33 rev. 2.8
Hardware Connection
Example 1 – Remote intercom key-panels, interfaces and wireless base stations
The following example demonstrates the use of X6R/V3R-FX-INTERCOM devices with intercom matrix systems.
An X6R-FX-INTERCOM is connected to eight four-wire ports of a central intercom matrix. The four-wire ports,
along with RS422 or RS485 control signals (device dependent), are distributed over the fully routable Optocore
redundant ring topology network to remote locations.
Intercom key-panels and various interfaces can be connected to the system at the remote locations.
