Larger quantities of audio input and output can be
accommodated by using the RIO rack.
Up to four RIOs can be connected to each C10 system.
All connectors are accessed from the front of the chassis
making it suitable for installation into equipment racks where
space is limited. The unit is cooled from front to back using
temperature controlled low-noise fans so space for ventilation
must be provided behind the rack. A standard 600mm rack
would provide adequate ventilation.
RIOs can be fitted with one or two removable power supplies.
A single PSU unit has sufficient capacity to supply a fully fitted
RIO thus full PSU redundancy can be achieved by fitting two
units.
The RIO is equipped with slots for six plug-in cards. The uppermost slot is always fitted with the RIO Interface card. This
card is equipped with four, 64-channel MADI interface ports for connection to the console surface.
Each MADI link to the console has capacity for up to 64 audio channels (at 48kHz). However, the first console-to-RIO link is
limited to 62 audio channels only because two channels are reserved for sync and status information; the remaining three links
can access all 64 channels of bi-directional audio data. The maximum I/O capacity for a single RIO unit is therefore 254 audio
channels.

Gp i/o

The RIO interface card is equipped with 24 circuits of opto-isolated input and 24 relay-closure outputs. Connectors are
all 25-way D-type female.

iBRe onnection
RIO units are connected to the console processor using duplex fibre optic cabling. The connectors required at each end
are duplex LC type – flat end, not APC.
The fibre interfaces are available in two versions: singlemode and multimode. The fibre specification chosen determines the
maximum distance that a cable can be run without loss of data. Singlemode and multimode interfaces and connectors are
almost identical in appearance but are operationally incompatible – the standards must not be mixed within a system.
RIO and console interface adaptors are fitted with the multimode version. Singlemode adaptors are at additional cost.
Each RIO unit is supplied with one 2m multimode fibre cable for connection to the console surface. It is the responsibility of
the facility to provide longer fibre cables necessary to remotely locate the RIO units or the additional cables that will be required
to support higher numbers of audio channels.

The RIO chassis provides SNMP data over the fibre MADI connection to the SBC computer in the console surface.
