Device Description
Optocore TECHNOLOGY
Optocore™ is a technology platform for sending large amounts of audio, with very low latency around a fiber-based
network. This transport (and management system) is of very high quality, suitable for concerts, recording studios,
and broadcast applications. SANE™ is a spin-off technology that adapts this same technique to a smaller network
(Ethernet) and at a lower cost. The SANE connections are used to provide expansion units at any fiber node.
ProGridinterfaces use both Optocore and SANE technologies to provide a high quality low latency media transport
system. ProGrid will interface with all other OEM products utilizing the Optocore technology, for example Yamaha,
DiGiCo and AVID.
The PG2-MADI-C-FX is a digital I/O unit and interface to the ProGrid Signal Transport Solution. The unit provides
two coaxial optical MADI input and two coaxial MADI output ports, allowing the transmission of up to 128 input and
128 output digital audio channels. Sample rates up to 192 kHz are possible. 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.
Redundant fiber connections can be established using the two provided SFP based LC multimode optical LINK-
interfaces. The dual redundant ring structure provides maximum safety in a network with an outstandingly low
latency. It facilitates the use of the advantages of fiber optical transmission in all sorts of temporary and permanent
applications, especially when long distance connections and high-quality audio are required.
The PG2-MADI-C-FX enables you to connect 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, giving up to 128 input and 128 output channels
additionally.
Two built-in Ethernet ports may be used to tunnel 100Mbit Ethernet through the OPTOCORE and SANE networks.
The PG2-MADI-C-FX together with ProGrid R-Series devices and YG2 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 PG2-MADI-C-FX.
The PG2-MADI-C -FX provides both word clock input and output. It includes bi-directional composite video
interfaces. Four RS485 ports allow the transport of a wide range of standards such as RS422, DMX, MIDI, and
CAN-Bus. In addition to the audio signals, video and data signals are transmitted by the fiber connection. The dual
power supply unit, with automatic switchover, permits a redundant power supply and safeguards against
malfunctions of the unit if one power supply fails to run.
The PG2-MADI-C-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 huge amount of channels exchanged by one PG2-MADI-C-
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 fiber optical connection. This keeps the system highly flexible in order to build the
network exactly suiting the applications need. A PG2-MADI-C-FX, for example, can transmit 128 channels to a
digital console system from various ProGrid devices such as PG32-AES-FX, PG16-FX or PG8-TP. If only eight
return channels from the console are required, only these eight channels instead of 128 inputs can be received at
the PG2-MADI-C-FX and transmitted via fiber optical connection, leaving the other channels to be shared by the
other network devices. Networks with several PG2-MADI-C-FX and other ProGrid 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 fiber optic transceivers distances from 700 m up to 70 km can be covered.
The dual optical interfaces with data transfer rates of 2 Gbps are equipped with LC-connectors, commonly used
and absolutely reliable in permanent installations.
Due to SMD production the PG2-MADI-C-FX fulfills the demand of highest digital standards occupying only one
