Device Details
Optocore Fiber 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
Principal Ports for AES/EBU
According to the AES/EBU standard each physical channel contains two audio channels - with the 32 digital of
the four principle ports 64 audio channels are available. The ports feature the unique possibility to define them
freely as AES/EBU inputs or AES/EBU outputs in groups of four.
OPTOCORE CONTROL software should be used to enable, disable and configure 32 digital channels as inputs
or outputs in groups of four. For more details refer to the Optocore Control Software Manual.
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..
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
DD32R-FX supports Optocore and SANE Ethernet transport. Two LAN ports interface with all other LAN and
SANE/LAN ports in the Optocore and SANE Network creating a large unmanaged virtual 100Mbit Ethernet switch.
Please note:
DD32R-FX principal AES/EBU ports are NOT equipped with Sample Rate Converters,
Every 3
rd
party device must be locked either to the Word Clock embedded in AES3
frame or to the External Word Clock output of DD32R-FX
