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). Aux12V 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
µ
s @ 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.
