Sync Source; Madi Link Connections - Solid State Logic C100HDSS Installation Manual

Section 5

Sync Source

The Blackrock processor must be provided with a source of sync input in order to function. Suitable sources of sync are:
The sync input provides internal 75Ω termination.
RIO – MADI Fibre Links
The Blackrock processor is supplied with four MADI ports as standard but may be expanded to provide eight ports (as
shown opposite). The RIO unit is always equipped with four ports.
Connections between the Blackrock and RIO units are made using industry standard multimode (50 micron) duplex LC
fibre cable assemblies. Multimode fibre is suitable for cable runs of up to 550m. Suitable fibre cable assemblies are widely
available from cable suppliers.
Singlemode fibre multiplexers can be specified for the Blackrock and RIO as a cost option. These will require matching
singlemode connectors and cable assemblies. Singlemode cable is suitable for distances of up to 2km.
The first MADI connection between the Blackrock and any RIO will provide 62 channels of bi-directional audio (two
channels are used to transfer sync and status information). Subsequent connections added to the same RIO will extend
the capacity by 64 channels for each lead.
A maximum of four RIO units can be connected to a Blackrock processor.
For additional security, a redundant fibre link can be connected between the Blackrock nd the RIO. The backup fibre cables
should be connected to the port directly above the primary port (1 and 5, 2 and 6 etc.)
RIO – Sync Output
The 'Sync' connector fitted to the front of the RIO interface card provides an output of Wordclock at the system's clock
rate.
RIO – Ethernet
The Ethernet connector on the RIO interface card is non functional so does not need to be connected to either the SSL
or TCP/IP networks.
